After Matrix drops Sully off the cliff and returns to Cindy she asks him, "What happened to Sully?" At this point, Matrix has never referred to Sully by name within earshot of Cindy, so she would have no way of knowing his name.
The scene where Bennet and Matrix are fighting towards the end of the movie, before Matrix kills Bennet they have each others throat in their hands and one of their backs is against the furnace. While they are grunting and groaning, if you listen carefully, you can hear one of them say "switch" just before they change positions.
When Arnie sets his stop watch to count down from 11hrs, each second that the watch ticks over there is a loud 'beep'. This is consistent with when he looks at his watch later in the mall, when it reads 9hrs 40mins to go, his watch is still beeping every second. Therefore, Arnie's watch should have been beeping every second of the movie in between these two scenes, but we never hear it. Also, when Arnie and Cindy arrive at the Sunspot Motel (7hrs 57min to go) and when Arnie's in the back of the police wagon, at 5hrs 2min to go, the watch no longer beeps with each passing second.
Matrix, a former Army Special Forces commando, secures his grenades to his tactical vest by tying the pins to a metal loop on the vest. No soldier with even a minimum of combat training with ever do this, due the hazard of the pin being accidentally pulled out, and killing yourself.
The airstairs at Val Verde Airport say "Aire Servicio", which is an incoherent, word-for-word translation of "Air Service" into Spanish. (Translated back into English, it would mean something like "Service. Skies.") The correct translation would have been "Servicio aéreo".
The police are marching Matrix out of the gun shop, they didn't even put hand-cuffs on him! I think I would put hand-cuffs on a guy who just smashed open a gun shop and was stealing all the guns he could get into his hands.
In shots of the seaplane near the island you can see the struts of the landing gear indicating that the gear is extended to the down position. However, in a water landing the wheels would remain retracted. The wheels would only be extended if they planned on taxing the plane up a ramp onto dry land.
At 52:05 John Matrix looks at the coordinates which are N33°13' W119°18' and says "these coordinates are somewhere near Santa Barbara. Those coordinates are nowhere near Santa Barbara, they're at San Nicholas Island, 87 miles (140Km) off its coast. However, when he finds them on the map, he points right to San Nicholas island.
During the big shoot-out near the end of the film, Matrix is using an M-60 machine gun which repeatedly acquires more ammo (the ammo belt is replenished) even though Matrix has no spare ammo with him, nor any time to reload.
When Matrix is raiding the surplus store, and enters the hidden room full of guns, he grabs the rocket launcher off the wall and hands it to Cindy. After he says "Go!" and she leaves the room with the rocket launcher, the next shot of Matrix shows it hanging on the wall again.
When Matrix is viewing the barracks with his binoculars, he is seen moving the binoculars from right to left. However, when the view switches to show through the binoculars, they are clearly moving from left to right.
When Matrix is gearing up to go and find Jenny, he paints his arms and face with camouflage paint and then puts on his combat vest and you see his chest is unpainted. Yet later on when he gets caught in the grenade blast and takes it off, his chest is painted.
At the end, when the helicopters and the sea plane land at the beach, you can see a cruise ship in the background in a wide shot. A later wide shot shows the pier and open sea, but no ship. Then in a final shot, you see the pier and the cruise ship.
When Matrix bulldozes the entrance to the surplus store, there is debris blocking the entrance. Cindy needs to step over this debris on her way, yet is able to roll a shopping cart full of weapons and ammo out the same path on her way out.
When Matrix jumps from the landing gear of the plane, he lands in water and gets his trousers and some of his jacket wet. Although he takes his jacket off, in the next scenes, his trousers are completely dry again, only a minute or so after getting out of the swamp.
When Matrix is "shopping" he puts many guns in the cart but he grabs the pistol and the shotgun shells after he tells Cindy to leave with the cart. Then he is arrested and the weapons that he grabbed after Cindy left are obviously confiscated, yet when he suits up on the beach for battle the pistol is one of the weapons he has and during the shootout the shotgun is fully loaded.
At the beginning of the movie when Arius' henchmen shoot at Matrix's home, Matrix has a cut on the side of his forehead which keeps appearing and disappearing in between shots while he's talking to Kirby's soldier, Jackson.
When Matrix arrives on the island and exits the dinghy in the water before pulling it ashore, you can see that he has white swimming trunks on which magically turn black in the next scene (4.3 version is better as the screen appears closer).
Immediately following the kidnapping of his daughter, Matrix is confronted by the thug who tells him he must cooperate if he wishes his daughter to be returned. Matrix is holding a G3 assault rifle, but when he shoots the thug it is clearly a pump action shotgun in his hand. In the next shot Matrix is holding the G3 again.
When Matrix arrives at the airport, Bennett is in a Mercedes. The passenger door can be seen to have no rain guard along the top. When Matrix sticks his head in the door to talk to Bennett, a rain guard is clearly visible. As Matrix walks away, the rain guard has disappeared.
During the fight scene with Cooke in the Motel room, Matrix grabs Cooke's arm with the gun and rams it through the glass panes by the shower. While doing this, they knock down the lampshade, which miraculously reappears in the next scene.
After Matrix and his daughter are first shot at and crawl into their house, Matrix is talking to the soldier/guard to see if he's okay. The blood on Matrix's forehead appears and disappears between shots.
When Sully buys the passports in the mall restaurant, he puts them in his pocket, but when he leaves to see whats happening outside in the mall the bag with the passports are clearly sitting on the table.
Shortly before Matrix enters the mall, we can see a white pick-up truck and a grey Renault LeCar stuck in the traffic. At this time, the right headlight and the front bumper on the LeCar were broken. During the chase scene, shortly after leaving the mall, we can see both cars again. Except that the car has been fixed.
Just before Bennett breaks through the door of Jenny's holding cell, you can see about 40 yards up the corridor, which is empty. However as soon as he breaks through the door barely a second later, a group of soldiers run past the door from right to left.
As Matrix exits the shed and picks up the M60 machine gun, he fires at infantry to the right of him. In the next scene, a close up of Matrix's torso, shows a strap across his chest which was not there when he exited the shed.
Right after Matrix and Henriques take their seats on the plane, the orange curtain behind Matrix switches from closed to open between shots. Shortly after that, as the fly hostess closes the curtain, she repeats the same movement twice.
After Matrix is merely scratched by a grenade and seeks refuge in the tool shed, He comes out with the machete and ax in each hand correctly, yet when he swings the ax up into the soldier's groin it is in his hand with a reversed grip.
When Matrix begins his decent in the Blazer (which is a 1973 or 1974 model with the Cheyenne trim package)the front grill is a 3 bar black insert (from a 1977-79 Chevrolet C/K series or G-series van) and the truck has black 4 wheel drive front hubs. A second Blazer (a base 1973 or 1974 model) is used during the shoot but has a basic gray grill (1973/74 Chevrolet C/K series), white front hubs and much smaller front tires.
During his final fight with Bennett Matrix can only use his left arm due to an injury on his right shoulder. However, when Bennett threatens him with the machine gun, he grabs a steam pipe with both arms and even throws it into Bennets chest with his right arm.
When Matrix is driving the red car and trying to run Sully's yellow car off the road, watch the front bumper of the red car. At some points it is hanging off the car, and at others is it attached onto the car.
At the very end of the film. When the 3 helicopters and the seaplane come into land, it is quite a wide show, with no boats visible. A few minutes later, when the seaplane takes off again, a big white boat is near the coast. Even if the boat was off camera during the landing scene, a few minutes was surely not enough to get that far, and that close to the shore.
At the start of the film we see two guys on the bin wagon. The one on the left of the screen already has his Uzi in his left hand, yet in the next shot we see him lean into the back of the bin wagon to pick it out.
When Arnold lets go of the landing gear he lands in the water. A few seconds later we see him walking up towards the beach, and we can now see that he is only wet from his waist down. It's not likely that he would have been able to land standing on his feet and not not becoming completely soaked.
Rae fires a rocket at the police van, first she fires it back to front then the second time she fires it correctly only this time she is knocked back by the recoil, why wasn't she affected the first time and pushed forward? Also there should be no recoil with a rocket launch.
When Matrix first rips out the seat of Cindy's car and sits in its spot, his body sits very low to the the bottom of the car. You can even see in the next scene that his head is clearly lower than Cindy's. However, during the chase scene, his head is level with Cindy's.
The style of Cindy's car changes when Matrix and Cindy are tailing Sully. Note the front grille with the center emblem that suddenly appears, the style of the headlight chambers that surround the headlight casings, as well as the two bumper guards that disappear and reappear. Obviously different vehicles.
When Matrix and Cindy are about to take of in the pontoon plane it is dark. Then as the plane takes off it is dusk with a little sun left, yet at the same time the view from the cockpit shows it is unbelievably dark.
While on the compound, there is a scene where some army guys are driving at Matrix in a jeep. They drive past some random army supplies and are about to surprise Matrix when he turns around and nails them with his rocket launcher. Or he sort of nails them. Actually, the army supplies that they had just passed have suddenly relocated and are crashed into by their jeep. Rewind and play repeatedly for full humor effect.
When Sully flees the mall in his Porsche he runs into Matrix, knocking him up and over the car but also knocks off his wing mirror in the process. In the driving scenes that follow the mirror is back on the car.
In the fight scene where Matrix and Bennett are trying to force each other against the furnace, watch Bennett's hands as he struggles with Matix. In one shot Bennett has his hand pressing against Matrix's face, in the reverse shot he is holding Matix by the back of his head/hair. His hands switch back and forth several times.
After Matrix throws the police officer into the bunch of officers at the mall, he runs at Sully, and you see the guards are beginning to get back up on their feet, but then you see them again a few seconds later, and they are back on the floor again.
When Matrix is infiltrating the base (just before he blows everything up), and just after he has cut a soldier's throat and planted a bomb, he is confronted by two more soldiers walking along with rifles slung. Seeing Matrix, the two frantically start un-slinging their rifles. Matrix throws two knives at them. Next we see the two soldiers falling with knives in their throats... and the one on the right has his rifle fully slung again.
When Matrix and Cindy follow Sully from the airport to the shopping mall the front license plate of Cindy's car is missing. When they arrive inside the mall parking ground it is back again. Later, when they follow Sully from the mall to the point where they intercept him, the plate is gone again.
In the beginning when Arnie starts pushing his truck it is a 1973 Chevy blazer that has a very distinct raised plastic grille that was only used on that year, but before the first jump it changes to a 1974 blazer which has a thin aluminum grille, and also has damage to the front left quarter.
When the chopper is about to land, Matrix says "I'm not going anywhere", and stares at his (off screen) daughter in an 8 o'clock position. Yet a frame later, with her on-screen, he is looking downwards.
As we see Matrix enter his gun shed, he picks up a pistol and tucks it into his pants. He then runs back to the house and kills the guy in the chair. As he leaves the house, the gun is now tucked into his belt.
As the two garbage men are shooting the guy at the start of the movie, we see from the side shot that they are standing parallel to each other a few feet apart and they stay still as they shoot him. Then when the camera changes angles to the front shot after the dead guy falls, we see the bad guy on the right has moved a few feet forward.
During the attack on El Presidentes house Matrix is seen using the belt fed machine gun. One shot shows him firing it apparently left handed (the film has been flipped as mentioned before) with a strap diagonally across his chest. The shots immediately before and after this he does not have the strap. A couple of shots later he is seen picking up a gun with a strap and putting it over his head. The next shot is the same one as previous but flipped back to its correct way.
When Matrix first abducts Cindy and is talking to her in the car, both of their windows are rolled up. When she backs the car out, the passenger side window is rolled down. In the next shot, as they exit the parking garage and pay the attendant, both windows are rolled down.
During the ridiculously overdrawn action sequence at the end, Arnie has a belt-fed machine gun which becomes lefty and righty through certain shots. Since Arnie isn't lefty, and it's unlikely that the army would just have a lefty belt-fed gun lying around, it's safe to say that the picture was reversed.
In the hotel fight scene between Matrix and Cooke, Cooke is knocked on the ground and shoves a red suitcase out of his way, and it lands near the door to the adjacent hotel room. When Cooke is knocked to that exact spot a few seconds later and grabs the gun, the suitcase is gone.
When Cindy and Matrix are following Sully, there is a shot from inside Sully's Porsche and there is a big green what looks to be a lorry following 2 cars behind. The camera cuts and it is no longer there.
In the final fight scene Bennett opens a furnace door into John's face, knocking him to the ground. When he opened the door it was two half-doors that opened together, yet in the next shot when he rips the door off to throw at John, only the bottom half is still there.
The rocket launcher. It has 4 barrels. Which means 4 shots. Cindy uses 2 rockets to save Arnie from the police truck. When he is using the rocket launcher when he is saving his daughter, he fires 2 rockets. 1 at the jeep behind him and 1 at the large impassable door. But when you see him fire these 2 rockets, they both come out of the same top right barrel. Why would he need 4 barrels if the rockets come out of a single barrel?
Halfway through the movie, Matrix is checking out the house where they keep his daughter. We then see a shot that shows what he is seeing through his binoculars, as he looks from the left to the right. Strangely, the landscape seems to move in the same direction as he is moving the binoculars, whereas normally the landscape would be moving in the opposite direction.
At the beginning of the movie when Matrix is driving his truck down the mountains after the bad-guys, there are two mistakes. The first is that just before Matrix's truck crashes, the two cars he's chasing (the car and the van) are very close to one another, and Matrix drives right between the two cars without hitting either of them. This is because after you see the shot of the two vehicles close to one another, the next shot you see the van that was following the car is way behind and totally misses Matrix's truck. The next mistake is just before Matrix's truck falls off the little cliff, you see many trees in front of him (where the cliff was supposed to be), however, once the truck actually falls off, the cliff is there with no trees around it.
At the end when Alyssa Milano is standing next to Arnold, in the wide shot you can see it's him, but in the close-up of Alyssa the person standing next to her has blond hair on his chest while Arnold is well "shaved clean".
When Matrix and Cindy are getting into the plane, the guys on the docks are shooting at the plane. You see several bullets make holes on the right side of the door. Later when you see the plane, the holes are gone.
When Arnold is crashing into the gun shop in the caterpillar you can see the camera to the rear (a black round one) and then also the camera at the front can be seen as a yellow box, attempting to be disguised as part of the engine block. These quickly disappear in subsequent shots.
During the motel room fight scene when Cooke crashes into the other room, the door separating the rooms changes between shots. When he first crashes through the door it's just a wooden door with a large brass knob, but when he lands on the floor in the other room the door is now surrounded by a white frame and the knob is visibly smaller.
In the dealership, Cooke never shifts the Cadillac into reverse, and yet instantly starts backing up after he says he likes "the price." The car would have had to be in Park or Neutral in order to be cranked up and would not start in gear.
Matrix's camouflage make-up changes style between shots (watch the thick line to the right side of the nose), furthermore, sometimes it's brilliant and shiny, others mat and dry, with no continuity at all.
During the fight at the end of the movie between Matrix and Bennett when Bennett calls Matrix a "dead man" and he responds with "Bullshit" you see him come off the wall with his left hand. He is throwing a left hook, but in the very next shot when the punch comes in contact with Bennett his fist is going from right to left in a backfist motion, rather than a left to right hook.
Right when the fight between Matrix and Bennett begins, the Uzi submachine gun vanishes from Bennett's right shoulder (it was on a strap). Then suddenly at the end of the fight (after the fell down over the railing and to the next level down, the Uzi reappears when Bennett picks it up and attempts to shoot Matrix. Bennett lost it on the upper level nowhere near the railing, and it somehow appeared on the lower level away from the railing.
When Arnie is escaping from the aeroplane at the start, he has a cut on the right hand side of his forehead. When Arnie (or his stuntman) climbs out onto the landing gear, the cut is on the left hand side of his forehead.
During the machine gun scene at the en Matrix has a belt fed M60 machine gun. When the fight starts, he has plenty of bullets. A few seconds later he has about 20 cm length of the bullet belt left. Scene switch - and he has more bullets. This switch between low and high ammo a few times.
As Matrix and his daughter are eating their sandwiches at the start of the film we see Matrix holding his sandwich looking out the window when he hears the chopper. Then, as the camera angle changes, the sandwich is now back on the plate.
After Matrix lands on the island and kits himself up, the camera zooms out to show him fully geared up; pay attention to the binoculars hanging from his neck - they are different to the ones he uses a minute or two later.
When Matrix boards the plane towards the beginning of the film, it is early evening - the sun is shown to be low in the sky, casting long shadows. Once he has escaped from the plane and is making his way back across the runways into the airport building, the shadows are smaller and more intense, showing the sun is more directly overhead - therefore it has suddenly become much earlier in the day.
In the mall, before the girl enters the bar, a guy in a blue and white shirt is half a metre away from passing next to her. Camera shot on Arnold, then back to the girl, and now the walker, plus the passers by around, have stepped backwards several metres and repeat their movements again.
During the long shoot-out at the compound, Arnold shoots down a whole army of bad guys. When he reaches the fountain, he shoots at about 3 or 4 people from a bird's eye view. If you watch closely, you can see one of the guards dive on the ground and play dead before Arnold's stream of bullets reaches him. Given what was happening at the time, that may have not been a bad idea.
After Matrix kills Sully he tips the yellow Porsche back on its wheels and we see the hood ornament is gone. As he and Cindy drive away it's magically reappeared. Then as they go through the city it's gone again.
At the end of the film, when the Army are arriving on the island, the amphibian plane is beached, with the nose facing the beach and the camera. In the next shot, when we see the same plane again, it has been moved out about 50ft, and turned round.
After killing Henriques on the plane, Matrix asks the flight attendant how long the flight to Val Verdes is. When he asks her the question, her hand is on the curtain separating first class from economy, but in the next shot her arm is by her side when she answer's Matrix's question.
When Matrix is in the gun shop, you see him take the missile launcher off the wall, but then in another scene, it is back on the wall again. Also, watch how easily Cindy runs with the missile launcher to the shopping cart. I guess those things don't have any weight to them.
At the end, where Matrix kills Bennett by throwing a pipe through him (OK sure, but let's just pretend). The pipe goes through Bennett, and into a steam pipe behind him. Then steam pours out of the Pipe that Matrix threw. Now what happened to all of the flesh, bone, skin, and blood that was inside of the pipe?
After Matrix tears the passenger seat out of Cindy's car and gets inside, the car door window is clearly visible, but in the following shot where Cindy pulls out of the parking space, the window is down.
When Matrix gets captured at the beginning of the movie the M-16's shoved into his chest by the baddies have the old-style three prong flash suppressor on the barrel. After Bennett reveals himself, a newer A1 flash suppressor (well, newer for that time anyway) is shown.
When Matrix escapes from the aircraft during take-off, he leaves doors open and breaks down sealed curtains. This would set off alarms in the cockpit and leave the aircraft unpressurized in flight; and therefore unable to complete an 11hr flight.
When Matrix crashes his car while chasing Sully, neither Matrix nor Cindy are affected by the crash even though neither are wearing seat belts (Cindy isn't even in a seat!), and the crash was powerful enough to severely damage the front end.
When Matrix is following the kidnappers with his sabotaged truck he goes down the forest in a straight line. The guys he's chasing use the road, which has several turns. He would actually overtake them after the second turn. Yet every time we seem him he is about the same distance away from the cars he's chasing.
The scene where Arnold is nearly killed by a hand grenade. The grenade is an M-67 frag grenade. It has a kill radius of five meters. That's roughly 15 feet. It explodes just as he is diving over a bush. The blast appears to be much closer than fifteen feet from him. In reality, he would not have survived.
When Matrix gets his weapons from the shed during the attack that ends with his daughter being kidnapped, we see him pull back the loading handle on his rifle - however, the weapon is a Heckler & Koch HK91 which fires from a closed bolt, meaning that to make it ready to fire you actually have to slap the cocking handle into the forward position (after inserting a loaded magazine). Note: It's the same action you see Keanu Reeves perform on a H&K MP5K submachine gun (basically the compact submachine gun version of the H&K rifle) during the "lots of guns" scene in... The Matrix.
Towards the end of the movie when General Kirbys female enlisted clerk comes in and says "General Kirby, you'd better get out here, we have your message on the teletype", this would never happen, as nobody would ever tell a general "you'd better get out here "unless it was another General speaking to them.
A flight attendant tells Matrix that the plane will land in Val Verde in "exactly 11 hours" and makes no mention of a refueling stop somewhere en route, either during that conversation or in the public address announcement made moments before. However, the aircraft in question is a McDonnell-Douglas DC-10-10, which has a maximum range of 3,800 miles or about 7 hours.
The shot of Matrix landing in the swamp after jumping from the plane isn't consistent with the free fall. The final shot indicates he has not fallen more than a couple meters. On top of that, after jumping from a DC-10 doing over 150 mph, he has no forward momentum when he lands.
If the access hatch to the nose wheel well on an airliner was opened at any time during the flight, every alarm panel in the cockpit would light up like a Christmas tree. In this case happening within seconds of takeoff the pilot would immediately declare an emergency, turn around and land at the airport he had just left.
The explosives that Matrix places by the buildings on the island are Anti-personnel Claymore mines. You can see on the back, it says "APERS MINE" (APERS MINE = Anti-Personnel Mine). They spray out steel balls designed to take out enemy troops. The relatively small amount of explosive in them is used to propel the steel balls to lethal speeds. There's nowhere near enough explosive in them to demolish those buildings the way that was shown in the movie. In regards to the point about explosives being inside the buildings and being "ignited by the blast of the mines". There's no way Matrix could have known about the explosives inside the buildings. He was OUTSIDE the buildings, so he would have no logical reason to place the explosives there. Also, some of those buildings were barracks for the troops. There would not be explosives stored in them.
A DC 10-10 (the Western plane that Matrix is forced to board) has a fully-loaded maximum range of 3,800 miles, but an 11 hour flight into South America would be closer to 6,000 miles. Even if the plane flew empty, it would barely be able to cover that distance, and many passengers and pallets of cargo are seen on board.
When Cindy and Matrix are in the warehouse, Cindy instantly knows that 250 gallons would get the plane to the island and back. It would be unlikely that she knows the rate of fuel flow, and, indeed, the weather conditions and type of engine, to allow her to figure this out.
When Matrix drives the car head on into the telephone pole, he gets out of the car with no injuries. It looks like he was driving at least 40 miles per hour. They weren't wearing seatbelts either, so both of them should have flown through the windscreen.
Towards the end there's a firefight between Matrix who wields a shotgun and El Presidente who is armed with a Steyr AUG. The weapon sounds used for the Steyr AUG however are from a MAC 10 or an UZI and don't sound a bit like it.
As noted elsewhere, it is simply not credible that Cindy, a trainee pilot, could land an seaplane so neatly, but it should also be pointed out that she banks into a low level formation on three helicopters - a very tricky maneuver, and then immediately after take off banks tightly into a high speed flyover of the squad on the beach. Both of these stunts would demand a very high level of skill from a pilot, especially one flying a lumbering old seaplane.
Matrix reads coordinates N33° 13' W117° (or possibly W119°) 18'. Neither LAT or LONG has seconds; just degrees and minutes, but he says, "These coordinates are somewhere near Santa Barbara". Even if you fill in 59" for the latitude north, it's still quite a ways south of Santa Barbara. If you fill in 119° it takes you farther west out to sea: that much further from Santa Barbara. The closest island to those coordinates is San Nicolas Island, and since they did go to an island later, that must have been it. Still a far cry from Santa Barbara. The handwritten coordinates would be much easier to read on Blu Ray.
Rae Dawn Chong sees a receipt for some aircraft fuel and comments that its "type 4" the kind used for amphibian aircraft. Well I've not heard of "type 4" and surely fuel used is differentiated by the type of engine not by the type of aircraft, JP4 is kerosene for jet engines and avgas for piston engines. (The plane they take has piston engines).
When Cindy first gets into the seaplane, she asks 'where are the LCD readouts? - I learned in a Cessna' as well as saying 'this plane is older than I am.' Any Cessna she learned to fly in would almost certainly be older than her, but even worse, Cessnas used for initial flight training (150s, 152s or 172s) certainly do not have LCD displays.
When Arnie enters the plane's cargo hold at the start of the film, he is confronted with a black dog in a cage barking at him. As he slides past the dog it seems to pay no attention to Arnie, but seems to be more interested in barking at someone else who is out of shot. Trainer perhaps?
Matrix enters his house through a door on the penthouse and a dead soldier by the edge collapses. His feet and legs should be blocking the door and the entrance, but instead, from the angle inside, it swings freely.
At the mall when Sully first sees Matrix, he grabs at Cindy's handbag wanting a quarter. It's amazing that Cindy first would have a quarter just laying around in there, but it's also amazing how quick he finds it without looking! What if he got to the phone and it was a nickel? He never even looks at it.
In the opening scene, Matrix is in the woods in a wife beater, but as he approaches his house, all the chimneys are pouring smoke as if there's a fire in each fireplace (or the furnace is going), which would indicate that the weather is cold. Jenny is also dressed in short pants.
During the fight with Cooke in the motel, Matrix mocks the fighting abilities of the Green Berets, which is the nickname of the U.S. Army's Special Forces. Everything in the film indicates Matrix himself is a former Green Beret, including wearing an Army Special Forces belt buckle.
Matrix is taught to be super stealthy and has deadly instincts like being able to smell his enemy downwind, so it doesn't make sense that he would rip the seat out of Cindy's car, causing a lot of noise and making Cindy gasp in shock, when he's trying not to draw Sully's attention that he got off the plane. Surely it would've made more sense to just keep Cindy quiet and recline the seat far enough to disappear from view, or hide in the back seat instead.
If Cindy doesn't know where the island is, how would she know how long it would take to fly there? Also she states that "Type 4" fuel is for an Amphibian (sic) plane. There is no such animal as Type 4 aviation fuel.
The red car was chasing the Porsche. The Porsche was destroyed on the driver side when it was flipped in the accident. When Arnold took off in the Porsche after he turned it right side up, the car was perfect.
When Matrix swings across the mall, his face is obscured by his arms. However you briefly see the stuntman's face as he lands, before the camera cuts to show Matrix preparing to jump from the top of the elevator. In the meantime you can clearly see the stunt man's wig fly up when he lands on the elevator;
When Matrix and Cindy are about to take off in the plane, the daylight varies: when they are filmed from outside it's about to get dark, from inside it's the middle of the night and then it's about to get dark again.
In the fight scene in the motel room, Matrix grabs Cooke's arm and forces it through the glass tiling in the bathroom. The tiles wobble and fall away without resistance and in a closer shot you can see that there is no cement or other bonding material holding the individual tiles together.
When Matrix and Cindy are flying towards the island and are discovered by the coast guard they dive towards surface to avoid radars; you can see the pitch changes - yet the vertical speed indicator is in a neutral position, indicating no dive at all.
Near the beginning after Cooke is on fishing boat leaving the harbor, you can see wires hanging from the back of the boat going back to the shore as it's trolling out. Wires presumably used to blow up boat.
When Matrix hits the button to blow up the village, you can clearly see that there are only cardboard stand-ups of men next to the buildings blowing up. Also, for some reason the top of the watch-tower blows up when Matrix never put a bomb there.
In the siege at the end, there is a shot where you can hear the squibs (small charges that explode on a stuntman to make it appear he was shot by a bullet) going off on one of the soldiers as Matrix shoots him.
Just before the guard in his tower gets killed and falls out, you can see the wooden sides have been precut. When he supposedly falls through the wood it parts along the cut line but remains hanging on string.
During the scene where Matrix is attempting to push his truck down the hill, pay close attention to the shot where the truck starts rolling and Matrix jumps into the cab - the cable controlling the truck is visible to the right of the rear tire.
When Matrix fires the multi-bazooka at the jeep, just before it explodes, a bunch of boxes covered with bushes suddenly appears right in front, most likely to hide all the stuff to allow for the explossions and chaos that follows.
During the stunt where the police van flips over (as a result of the rocket launcher attack) you can see the telegraph pole section used to flip the van over. It rolls down the road. (Stunts involving flips rely on a mini pile driver under the vehicle, as opposed to using an explosive charge by itself which can be too unpredictable).
At the end of the fight between Matrix and Bennett, Matrix throws a pipe through his body into the steam duct behind him. However, immediately after he is pierced by the pipe, we see Bennett slide about half a foot down the wall, which would be impossible with the pipe lodged in behind him.
The scene with the shack has many mistakes, but only if you play it in slow-mo. First, he throws the circular saw at the guy in the window, the saw is moving on wires and he has a hairpiece someone just pulls off with a wire. The next guy he stabs with a pitchfork, and Arnie just lightly stabs him and the guy falls forward holding onto the pitchfork to make it look as though he was stabbed. Arnie then throws a saw at a guy hitting him in the chest. The guy actually just catches the saw in his arms in a way to make you think he got hit. Then Arnie swings some sort of gardening tool into the gentiles of a man, but he actually stops it before it hits the guy and the thug just holds onto the handle. Finally, Arnie hacks off the forearm of a another man. You can tell that his arm was fake from the elbow on.
When Matrix reaches Arius' mansion (in actuality the Harold Lloyd Estate), he is rushed at by several soldiers of Arius' private army and starts shooting at them with his RPK. In one shot from Matrix's rear we can see him shooting four soldiers at the same time. However, the two soldiers on the far left drop dead even though Matrix is aiming his weapon to the right.
There is a scene in the mall fight between Matrix, and the security guards when he knocks one of them over a railing you can see the cord that's attached to the security guard's right ankle as he falls.
At the end of the film, we see Cindy beach the plane with the nose of the aircraft facing the camera. After the dialogue between General Kirby and Matrix, Matrix and Jenny go to board the plane which is now facing in the opposite direction.
In the fight between Matrix and Arius, Matrix rolls out and fires his shotgun repeatedly at Arius leaving blood stained bullet-holes scattered randomly all over Arius' chest. As Arius falls towards the window, the bullet holes can be seen all lined up in little sets of six.
In the final battle between Matrix and Bennett, Matrix is holding his knife in his right hand. However, when Bennett pins Matrix against the wall, Matrix manages to somehow switch his knife from his right hand to his left hand.
Before the final shootout, Matrix plants explosives on the edge and around the different buildings, yet when he detonates them, the explosions clearly come from the insides of the building (and the top of one of the watchtowers).
In the end when Matrix is fighting with Bennett, When Bennett is hitting Matrix with a metal pole, the metal pole is a very obvious rubber prop, because the metal pole bends when Bennett is hitting Matrix.
Shortly before Matrix kills Arius, he fires his assault weapon through multiple glass window panes, shattering most. However, no parts of the window frames are damaged, although when Matrix next jumps through the shattered windows, it is clearly seen that the frames are made of wood or an easily breakable material. It would be impossible for Matrix's bullets to have hit the glass windows only with no damage to the delicate framing around them.
