(at around 1h 9 mins) When the caravan almost runs over the goofy kid in the PVC pipe scene you can see the mic visible in the reflection of the windows on the caravan as the kid is being pulled to safety.
(at around 31 mins) If Clear was extremely worried about her safety, i.e. making the nurse collect anything possibly dangerous from visitors, then she wouldn't have a television monitor in her room. Since it could possibly burst shooting glass everywhere or even cause an electrical fire.
(at around 5 mins) In Kimberly's premonition, the hobo woman getting cans shakes the bag which makes the cans fall out. (at around 12 mins) After Kimberly's premonition, the hobo woman just holds the bag and the cans just fall out.
(at around 1h 14 mins) After the airbag deploys, the girl gets impaled by the PVC pipe. When the news is reporting the accident on the radio, the woman says her head was impaled with a metal pipe. It was a PVC pipe.
(at around 13 mins) After Kimberly has her first premonition (the highway), she parks her SUV across the on-ramp to block it. Yet, when her SUV gets hit by the truck, it has moved to being parked pointing onto the highway, and quite a ways out into traffic to have been hit so squarely by a passing truck.
(at around 26 mins) When Officer Burke is looking at the pictures taken of the dead survivors of flight 180, Tod, in the bath, has his hands to the wire round his neck as if he died whilst trying to pull on it to get free. However, in the first movie as he dies, his hands eventually rest by his side, nowhere near his neck.
(at around 14 mins) When Officer Burke approaches Kimberly's truck after her premonition, the camera shows a concrete barrier directly out her window, protecting her truck nearly to the front. Moments later, when the semi smashes into her truck, it hits nearly in the middle. The semi would have had to drive through the barriers to do this.
(at around 1h 15 mins) In Eugene's hospital room, the cart that his breathing machine is on rolls away from the wall and pulls the plug far enough out of the socket to cut the power to the machine. When the door is opened a few minutes later, the plug (which now plugged all the way in) is yanked out of the socket and causes a spark.
(at around 6 mins) On the highway with a police car behind her, Kimberly changes to the right lane and nearly collides with a truck, but the previous view of the rear view mirror showed they were already in the right lane; there was no truck in sight and both lanes were occupied by cars.
(at around 30 secs) At the very beginning of the movie, it is stated that Mt. Abraham High lost 40 students and four teachers in the plane crash in Final Destination. 40 students and four teachers boarded the plane, but six students and one teacher were removed, meaning that 34 students and three teachers died on the plane.
(at around 41 mins) When Tim is in the dentist's chair and the dentist is drilling his tooth, the dentist's hand go from both being on the right side of Tim's head to having his right hand holding the drill and the left hand around Tim's head holding the other instrument.
(at around 16 mins) Seconds after the (real) pile-up, Dano and Frankie gasp and turn their head. But in the wide shot of the car, you can clearly see that Dano is looking straight ahead, without turning his head to look at the crash.
(at around 11 mins) When Evan's car hits the diesel tank and explodes, he is driving the same way as Kimberly and the others. But after Kimberly flips, and she sees him burning, his car is clearly turned around facing towards Kimberly's SUV.
(at around 10 mins) In the premonition of the crash, after Eugene slides off his bike, Rory yelps and swerves to avoid a burning car. No cars have exploded yet. The burning car disappears when Rory is flipping over and over toward the camera.
(at around 8 mins) In the beginning of the movie, after the Hice truck passes by, there is a boy crashing his toy trucks in his dad's car. Dad's hand switches positions on the steering wheel from down, then top, then down again.
(at around 6 mins) At the beginning of the movie Dano is smoking a joint and holds it out when he sees the motorcycle chick flash herself, the boy next to him takes it from Dano and takes a drag, but in the next shot Dano is holding it out again.
(at around 10 mins) In the highway crash premonition, Kat hits a log with her Ford and rolls over and a close-up of her in the truck shows her airbag doesn't deploy. But later in the movie (at around 1h 12 mins) her airbag goes off when the fireman hits the truck with the jaws of life.
(at around 21 mins) After Evan throws his spaghetti out of the window, he puts the pan on the stove. When he does, there are a few pieces of spaghetti still on it, but the rest of the following scenes the pan is clean.
(at around 11 mins) In the crash scene, when Evan is driving towards the tractor-trailer and the camera is on his face, the windshield is missing from his car. In the next shot of him ducking down, it is back.
(at around 11 mins) Near the end of the crash scene, as the tractor-trailer explodes, a utility-vehicle type "bucket" is seen above the driver's side of the truck cab. It is not visible in any other shot of the truck.
(at around 10 mins) As Rory's car rolls over during the crash, both the driver's door window and the quarter window are intact and visible until the shot changes. When the car comes to a stop in the very next shot, the door window is either gone or rolled down, and the quarter window is broken out, though neither are seen breaking.
(at around 10 mins) When Kimberly's car is seen rolling, Eugene is hit by his bike and Evan hits the truck, you can easily tell these were dolls. You can see the wire to move the head of the doll on Eugene, the arms (which are incredibly flexible) when Kimberly's car rolls and the doll is just dropped to the side when Evan hits the truck.
(at around 41 mins) When Tim is in the dentist's office, the oxygen tank on the anesthesia machine has a white label. While this is the correct label color in Canada (where the movie was filmed), in the United States (the movie is set in New York), all compressed gas tanks containing oxygen have a green label (or the entire tank is painted green).
There are two mountains, in the real greenwood lake, but nothing like the mountainous terrain in Canada where the movie was shot. The lake is nine miles in length, and one mile wide. and stretches across state lines into new jersey.
(at around 1h 23 mins) Although it can be an understandable desire of the actress, when Kimberly is being defibrillated, you can see she is wearing a bra. During emergency procedures all clothes are cut off the patient.
(at around 28 mins) The news report shows Highway 23 as being an interstate highway. There is no Interstate 23 in existence. There is a New Jersey state route 23 not too far from Greenwood Lake however.
(at around 26 mins) When Officer Burke looks over the site Flight 180 survivors and sees four related crime scene photos, he looks over a picture of himself beside Billy Hitchcock in a body bag. According to the law and protocol a body must not be moved and or tampered with (only allowed to be moved by the coroners for collection), Billy has indeed been moved by Officer Burke, as his body with Officer Burke is now on the dirt track near the train tracks where he was decapitated. In the first film Billy upon his semi-decapitation had his body topple off to the right side of the track, collapsing down on the side of an embankment shrouded in trees.
New York State citizens were required to change and update their license plates from the original Red Statue of Liberty in the Middle to the blue mountain background (shown on the Police Car); cars that still had the Red Statue of Liberty license plate were not allowed on the road; however, both license plates were used in this film.
(at around 7 mins) When Kimberly's Suburban is blinking the Check Engine light on the dash - first, the light will flash only in case of a serious malfunction of the engine, such as a spark plug misfiring, which requires immediate attention. Losing transmission fluid is not an engine problem, and in fact the transmission overdrive indicator would blink, indicating a transmission problem. Two, the Check Engine light never has a beep associated with the light.
Prior to 2007 New York State Police did not use any blue lights on their patrol cars, after legislation passed in early 2007 they now use blue lighting in limited rear-facing applications not the front-facing use like in the movie.
At the end of Final Destination, Alex had just been saved, so Clear was next. But after that, someone (maybe even Alex) could have saved Clear so that it skipped her again, and then Alex died after that. Since Clear says she and Alex cheated death dozens of times, it must have even jumped back and forth between them several more times.
(at around 1h) When Eugene fails to shoot himself, Clear says it wasn't his time to die. At the end of the movie when Kimberly realizes she needs to drown herself, this would have gone one of two ways: 1) If it was her turn to die, Death would have just continued onto the next in line after her. 2) If it wasn't her turn to die, Death wouldn't have allowed it, and she probably wouldn't have been able to start the van.
During the police interrogation scene, Evan Lewis is kept separate from the rest of the group. Later, when his death is reported by the news, his fellow survivors are all intrigued by the report. However, none of them would have known who Evan was, and likely would not have been unnerved by his death.
(at around 7 mins) In various shots of the tractor-trailer during the crash scene, we see that it has a fuel tank mounted to the bottom side. Flatbed trailers do not have fuel tanks, as they have no need for them.
During the major accident, when Eugene falls off his bike and hits the log on the road, if you look just above the log when the motorcycle 'intercepts' with the actor, you can see what appears to be a crash pad above it.
(at around 21 mins) When Evan Lewis is in his apartment before the fire. His stereo turns on, but he really turns it off. You can see the display on the receiver disappear and the red standby light come on.
(at around 10 mins) In Kimberly's premonition, when Rory's car flips over we see the boot of his car go flying. Yet when the car is seen rolling after Eugene is killed by his bike, the boot lid flies off again. When the car stops rolling you can still see the doors are still on there and the bonnet is just bent, so it has to have been the boot.
(at around 10 mins) During the big pile up scene in the beginning of the movie we see many cars roll over and as a result we see the undercarriage of many vehicles. However, upon closer inspection you can see the round cylinders on one side of the undercarriage which are part of the mechanism that, when activated, uses an explosive charge to flip the car over. This usually involves what is essentially, shooting a large piece of telephone pole at an explosive rate of speed down through the underside of the car and onto the ground which acts as a jack of sorts. But at the rate of speed it happens due to the explosive charge, it not only lifts the car up off the ground but flips it over violently.
The goof items below may give away important plot points.
(at around 1h 19 mins) After Clear Rivers and Eugene Dix are killed by Eugene's room's oxygen combustion Dr. Kalarjian and a male orderly simply pass by them with the ECG machine, ignoring both character's corpses in the main foyer corridor. The single paramedic to arrive the scene moments later (to whom Kimberly claims the 'white van' ambulance from) tends to the recently deceased characters but does without any further assistance.
(at around 1h 23 mins) During the reanimation near the end of the movie, Dr. Kalarjian defibrillates Kimberly though the EKG shows a flat line. A defibrillation is only useful if the patient suffers ventricular fibrillation (where the EKG shows fast, irregular zig-zag lines).
(at around 1h 12 mins) When Rory gets cut in half by the fence post, it was shot in front of a green screen with poles holding up his legs as the top half toppled off. In the film if you look in the bottom right hand corner, you can see one of his intestines hit an invisible pole, then flip over onto the ground.
