Continuity mistake: People sitting beside Alex disappear at the funeral.
Continuity mistake: The plane that takes off and explodes isn't a Boeing 747. It should be because that's what they boarded.
Continuity mistake: After Carter wets himself, the urine stain changes shape.
Deliberate mistake: When Alex is in the cabin opening the can the pull tab is already lifted up making it easier to open because he is wearing gloves. It was already up when he took the wrapper off.
Continuity mistake: Late in the film, Alex Browning hides out in the cabin and attempts to make it as death-proof as possible, securing everything therein with ropes and duct tape, and carefully placing his kerosene lantern in a tray of water. At first, we see that the antique lantern is painted dark green; but, one scene later, the same antique lantern (in the same tray of water) is now painted bright red.
Continuity mistake: When Ms. Lewton dies, she is grabbing her bleeding neck with her left hand. While walking into the kitchen, she leans onto the kitchen table with her right hand. Later in the scene, when Alex comes and tries to help her, we see the bloody left hand impression on the table, even though we should see the right one.
Factual error: When the teacher gets killed, the vodka on the floor catches fire, and there's still enough alcohol left that the fire follows her? I don't think so - vodka will burn, but not that well.
Continuity mistake: When they are going through the gate to get on the plane, the teacher counts the pupils (in French). He counts upwards in ones, even when two pass him at the same time, arm in arm.
Plot hole: During the premonition, Carter and Terry are sitting directly next to each other. However, we know that before Carter dies, both Terry and Lewton (who is sitting 2 rows in front of them) have to die first. When Alex sees the report that marks the explosion path, it suggests there is a chain reaction that goes from Tod's seat to Terry's, and then Lewtons. If this is true, should Alex have not died with Tod and Carter with Terry? Tod can actually be seen getting hit in the head with somebodies luggage, and if this is how he died, the news report suggesting a 'chain reaction' is wrong; Tod's seat never explodes. Can anyone tell me if the drawing Alex did with the line going from seat to seat (before the explosion) is not supposed to be an explosion? If you slow down the premonition, both Terry's seat and Lewton's seat blow up about a split-second before the explosion erupts - this is possible but the distance of one of the explosions from Lewton is larger than the explosion from Carter.
Visible crew/equipment: When the train breaks Carter's car there is a camera man inside it.
Continuity mistake: In the scene where Billy gets his head sliced off by a piece of metal that fell off the train, as his head rolls away his hair is a much lighter shade of brown than it was during the rest of the film.
Continuity mistake: Near the beginning, when they are at the Memorial for the school, look closely to the right of Devon Sawa right after he and the other gal look at one another - an extra with red hair walks in front of him, in the very next shot Devon gets up, and the same extra is now behind him.
Continuity mistake: When Alex is talking to Clear in her garage, one strand of her hair keeps changing, first curled under, and then straight, back and forth...
Other mistake: When the plane takes off in Alex's vision, the plane begins to go into a nosedive, and the entire left fuselage is blown apart, sucking many people out of the plane. The plane then explodes completely, but in reality, the plane just takes off, and explodes almost instantly afterwards. No struggling with the plane is shown in reality, nor is the plane going into a nosedive. This is also proven in FD5, which is a prequel. The jet engine explodes, leaving a flaming tail, and the plane spinning out of control. The plane just simply "explodes" without any signs of struggle.
Suggested correction: According to the news report, "Officials believe deterioration of silicon insulation on an electrical connector to the scavenger pump may have leaked combustible fluids. A spark in the fuel switch in the fuselage may have ignited the fuel line and proceeded to the fuel pump which would have set off the catastrophic explosion." This spark, in the premonition, happened while they were already in the air, which is why the damage occured how it did. However, in reality, Alex has his panic, and they're escorted off. So instead of already being up on the air, the spark happens as soon as the plane takes off instead. Further, when you compare the timeline of the explosion in the premonition and the explosion in real life, roughly the same amount of time has passed, placing the explosion at the same moment it should have been to start with.
Suggested correction: Death will find any way to make sure that someone dies when they're supposed to, so regardless of how it happens, how natural is it when an invisible force is causing the explosion? Plus, just because Alex had a vision of it does not mean that the real-life occurrence will happen in the same way. It doesn't really matter how the plane exploded; all that matters is that it did.
Continuity mistake: When you see Alex watching the news report about the crash of 180, after coming back from the airport, you see his mum and dad asleep on the couch with a pillow at the end of his mothers foot and a few shots later after hearing the loud thunder, the pillow is lying on her ankles.
Character mistake: In scenes following the plane crash, authorities refer to the 'National Transportation AND Safety Board.' The organisation is called the 'National Transportation Safety Board' - no "and".
Continuity mistake: After Alex reads his porno and throws the magazine at the owl, that one piece of paper with "Todd" pops out of the fan after the magazine got stuck in it. Now, this is a very small mistake, but if you look at the shape of the piece of paper, the one short stump side changes between takes. Like I said, it's very small differences, but there are differences.
Visible crew/equipment: After Alex walks into Ms. Lewton's home before he discovers her blood on the floor, you can see a crewmembers shadow moving on the light brown TV table. (Note the shadow doesn't match Alex's movements).
Continuity mistake: A reporter takes a photo while Clear and Alex talk at the memorial. When we see the photo in the article, it's at a different angle and Alex has vanished from where he should be next to her.
Continuity mistake: Alex buckles his seatbelt when he first sits down on the plane, before the girls ask him to move, making him have to unbuckle to move for them. When he wakes up after his premonition, he immediately jumps out of the seat, not buckled in.
Suggested correction: Since we don't know exactly when he started dreaming the premonition, it's easy to assume putting on the seat belt was part of the dream.
