Continuity mistake: At the beginning Ava shoots the man's phone out of his hand through the car window. When the car drives away all the windows are intact.
Continuity mistake: When Kat and the protagonist have dinner, his hands swap between crossed or not depending on the shot. (00:28:32)
Continuity mistake: When Cecilia is talking to Adrian at the dinner table towards the end of the movie, the food on the plate is situated differently from shot to shot as they converse.
Continuity mistake: When Marcus sees his baby grandson, a nurse in the background is picking up a white diaper. In the close-up the diaper is now blue. (00:03:35)
Continuity mistake: SPOILERS: During the final scene, when Samuel L. Jackson is "puppeted" to lift his arm up to make it look like he's pointing a gun at the SWAT team, the number of laser-sights visible on his chest changes between cuts. In the wide-shot, there's only three, but when it punches into a close-up, suddenly there are five.
Continuity mistake: In the intro, the woman shimmies off her shirt, which pools on the bathroom floor. She finds the obligatory corpse, screams, and gone is the shirt from the floor. (00:02:00)
Continuity mistake: The amount of rain on The Man's shirt is relatively light when he reaches the doorstep but his shirt was saturated before he even started going up the sidewalk. He was in the house for a couple of minutes to kill the two people and set the house on fire (not enough time for his shirt to dry) yet his shirt was almost dry when he exited the house. The Man's shirt got soaked again on his way to his truck. The shirt looks dark blue when saturated with rain but light blue when it is dry. (00:02:53 - 00:03:51)
Continuity mistake: Anne Heche's jacket changes color from brown to pink, and her wool hat that had blood and coffee on it, is back on her head after being thrown away. (00:40:00 - 00:44:00)
Continuity mistake: At the market, Lee picks out five pieces of fruit (one apple and four oranges?), tears a produce bag off, and walks away. He takes a few steps off-screen, and he is next seen going around an end cap and walking down an aisle, with nine pieces of fruit in the produce bag. (00:01:36)
Continuity mistake: When the girls are standing on the beach with the flares to guide in the German aircraft they are in two rows just a few metres apart. The view from the aircraft shows them much further apart, wide enough for the aircraft to land between them.
Continuity mistake: The characters are on a tile floor that has one yellow tile visible among the black and white tiles. The next shot they're in a different spot on the floor with two yellow tiles visible. (01:22:10)
Continuity mistake: They travel without their helmets but when they are about to go underwater they magically appear.
Continuity mistake: A vast majority of the movie occurs over the course of a single day, so it would be expected that Becky's hair stayed about the same. However, there were frequent fluctuations in Becky's hair's length, how her bangs were arranged, and color (whether the blue streaks could be seen at all or how much at a given time, and if she had dark roots on the top of her head).
Continuity mistake: When the Homeland Security guy is sitting in the lobby in Vancouver, Canada, a girl and another man are walking behind him and across the lobby in the wide shot. But when it zooms in on him, the same people and more are walking behind him again as if they never were crossing the lobby. (00:28:45)
Continuity mistake: Running away from the guard after the burglary, Joey and Matt went down a fairly steep hill in the woods. After passing the hole, they walked up a small embankment to go toward home. The next morning, Joey is riding his bike down a steep hill (the one that was before the hole?) - so steep he has to get off his bike and push it. Halfway down, the camera shifts and Joey is suddenly on TOP of a small embankment, which appears to be the one he and Matt walked up the day before on their way home.
Continuity mistake: There is no way that so much time has elapsed between Marla arriving at Jennifer's dad's office and when she is following the driver. They arrive at dawn, leave the parking lot still in daylight, and it's already dark when she leaves him abandoned in the woods. The sequence of events does not justify the fact that so many hours have elapsed that it is already nightfall. (01:34:45 - 01:39:42)
Continuity mistake: The same couple are sitting behind Alex and Greville when they attended Cinderella and Swan Lake ballet at two different times.
Continuity mistake: James lit the cigarette he gave Amanda, and she was shown taking one puff. Amanda tells part of the Empty Man story and the ashes on the tip of her cigarette are the same when she takes a second puff. After continuing the story for about two minutes, the length of the ashes still have not increased when Amanda is about to take the third puff. (00:37:21 - 00:39:53)
Continuity mistake: Jim's Dodge Ram with a camper seems to change colors, mostly variations of gray. Initially, both are a light gray. Other times, both look white - or even blue. Sometimes, the truck is dark gray and the camper is white. (00:03:05 - 00:25:12)
Continuity mistake: Bernice's bangs go back and forth between having a small section separated from the rest to not separated. Before she kisses Thomas, her bangs are separated, but combed together when they are done kissing. (00:21:56)
