During the scenes where Frank is using the stethoscope in order to listen "into" the containers, the stethoscope suddenly disappears when he walks round a container towards another one. He didn't have time to take it off.
In the first car chase, as Frank is driving on the pavement, he drives by a restaurant with the blue copper chasing along side crashes through the table and chairs - there is a man who jumps out of the way to the middle posts, facing away from the camera - in the 'cool repeated action' shot he is facing the camera.
Early in the movie Frank's BMW is shown flipping the front license plate to a different number. A little later when Frank is shown changing the front license plate on the BMW in his garage the car has a standard license plate attachment and a standard license plate which would make it impossible for the license plate to flip.
When Frank and Lai escape the burning house via the exit in basement they jump into water. Frank comes up with diving equipment but Lai never puts on any fins. However in the next few shots where she's diving and getting out of the water, she has fins on.
When Lai is sitting at the table with a drink in her hands and her father slaps her, the cup and its contents fall to the right. In the next shot of the table, the cups on the right and the spillage is on the left. In the final shot the spillage is on the right again, yet the cup has moved closer to Lia's hands without being handled. Also, she begins spilling the cup before he hits her, even though she doesn't really move till he hits her.
On the last scene of the first chase, on the pier, Frank crosses the railroad just after the train passes by, leaving all the policemen on the other side of the railroad. Just a second later a policeman gets to cross the railroad and the warehouse on foot to try to shoot the BMW, and the train is already still.
Towards the end of the movie, during the car/truck chase, one of the Mercedes crashes and skids all over the motorway. The Mercedes has gleaming alloy wheels, but when it is in flames, it has steel rims, not alloys.
During the first chase scene with the cop in the blue Peugeot, after smashing though the plastic furniture on the sidewalk, the cops license plate has partially fallen off. In the next shot were the cop almost hits the motorized pole the license plate it back to the regular position.
When Frank goes back for revenge for blowing up his BMW, he crashes through the wooden gate and the Mercedes he's driving the grill get broken, but not in the first shot after he breaks through. In that shot the grill is fine, but not in any of the following shots.
In the scene where Frank brings a rifle into the shipyard, the stock on the gun is seen folded. He fires some rounds at a couple men with it folded. A few shots later, the stock is unfolded and Frank is using it like he's supposed to.
In the opening chase sequence, When Frank reverses the BMW off the car transporter the left hand door mirror hits the support column for the trailer decks and is bent forward, a fraction of a second later as the BMW drives away the mirror is back in the normal position.
Lai's hair appeared to be relatively straight when she was shown bound and gagged in Wall Street's basement. Her hair was suddenly much more curly in the next scene where Frank takes her to his house later that night. She couldn't have had a chance to fix her hair since she was tied up the whole time.
When Frank and Wall Street are fighting in the truck cab, especially when Wall Street is about to kick Frank through the windshield of the truck, a driver's hands can be seen on the wheel in shots from outside.
Just before Frank's BMW is blown up, his white collar is visible as he walks toward the car. The instant the car explodes and Frank leaves his feet his coat is pulled upward and covers his white collar, and the harness (used to lift him off his feet) is visible under his jacket at shoulder level.
Frank is told to deliver the package (with Lai) to "Rue de Luxembourg", however when he exits the gates of the house, the street signs says "Avenue de Saissy", the real name of the street in Cannes, France.
During the bank heist at the beginning, one robber shoots another to conform to the deal with Frank of only transporting three people. However, blood splatters on the back window indicating an exit wound. If there were an exit wound the bullet should have gone through the back windshield as well.
When Frank raids Wall Street's villa for revenge, he dives behind a detached door on the ground for shelter against the fire from the bad guys. In real life those bullets would easily penetrate that wooden door and the door would be useless for protection against firearms.
When Frank's house is being attacked, despite the gunmen firing high-powered assault rifles on full-auto and while standing, there does not seem to be any significant recoil as all the bullets strike Franks's house at roughly the same height. Given the distance and style of fire, this is simply not feasible, no matter how skilled the marksman.
When Frank jumps on the top of the container being carried by the forklift, you can see the whole thing wobble. An empty 20 foot cargo container weighs 4850lbs and the forklift is at least 3 times that. A 200lb man would not be able to cause that much movement by landing on it.
When Frank falls backwards through the trucks glass, it crumbles into thousands of individual small pieces. While windshield automotive glass is tempered safety glass and designed to break into small, rounded pieces, they should stay together. Windshield safety glass has a plastic sheet in between two layers of tempered glass, so that while breaking, they do not shatter as a complete sheet.
Many goofs here complains about wrong continuity. In fact, the editing style of the movie often uses technique known as "time squeeze" for faster unwinding of the action. In these scenes they are cutting out minor details (such as paying for drink, putting fins on, taking off stethoscope, unfolding stock of the rifle, arriving of Lai's father's car in the final sequence and so on).
Lai is tied to a chair (hands and feet). She is able to get to the car by tiptoeing. How does she then open the door, drag herself and the chair into the car and close the door behind her? Not to mention the fact that someone as careful as Frank steals the car without noticing a woman tied to an office chair in the back seat.
When Frank runs up to the crop-duster with his plane in the field, the crop-duster says "good morning" to him in English regardless of Frank being a) In France and b) not saying a word to him in introduction to reveal himself as being English.
After Frank drops off Lai and stops for a snack, his BMW is blown up. During the explosion, Frank is blown backward and upward but nothing else is. Above his head is a black flag which continues to flutter gently in the breeze. And the lightweight tables and chairs which are very close to the car do not move at all. In addition, the explosion comes from underneath the car and the car jumps up in to the air. But the bomb was in the briefcase inside the car so the car should have stayed in place and, if anything, the roof or windows should have blown up and out, not the entire car. Also, Frank should have been blown backward only, not upward as well.
During the truck fight, "Wall Street" is clearly replaced by an older stuntman when he is kicked and swings out on the passenger door of the truck. The harness/apparatus the stuntman uses in this shot can also be seen.
During the fight scene in the hallway at the villa, it is very apparent that the two axes used in the scene are made out of rubber, as they bend and regain their shape when they strike the hallway wall.
When Frank puts the pedals on his feet during the oil fight, they only have a strap across the top but in the close up of his right foot, you can see a strap going around the heel to keep them on his feet.
During the oil-slick fight scene in the warehouse, several close-up shots of Frank show the oil on him as becoming dry and crusty, something which oil does not do but the molasses used for the scene does.
When the car comes out of the alleyway with the steps, it is in reverse, even though there was no room to turn around. Also, when Frank says, "See what I mean about the shocks?" you can clearly see the car is going forward (you see a window pass on the wall).
