Continuity mistake: After Dave stabs Ravi, the shot cuts to Kurtis running through the woods trying to escape. Ravi (in the clown costume) is seen among the ones pursuing him, but he's either dead or dying at this point, and, obviously, cannot chase someone while riding an ATV. It's a recycled shot from when Tommy was attempting to escape.
Suggested correction: It isn't Ravi on the ATV. Towards the beginning you see Dane on the stairs talking to 3 students, a little later on in the cafeteria you see the same 3 students sitting at a table and the shots keep switching between them and Dane and his friends, and Dane says something like "and they will be in the woods dressed in the same outfits/costumes as us." It's meant to confuse the cops when they show up.
Continuity mistake: In the scene where Beau and Chiles are in the hotel room, with Canter knocking on the door, Chiles puts on her shirt twice.
Continuity mistake: In the scene where they left 'the cottages' in the red Volvo estate to go to the town to look into the travel agent window, the car first displayed a G registration plate but subsequently changed to an A registration.
Continuity mistake: When Wally is talking to Sebastian in his bed, the latter has lost two of his bottom teeth. For most of the rest of the movie they are there. In the last scene they are gone again.
Continuity mistake: 25 mins into the film, Helen's thick black shoe heels have changed to stiletto heels. Her shoes change back at 37 mins. I noticed this several times throughout the film.
Continuity mistake: In the scene where the team is in the process of clearing the sniper, Miller says, "When the 203 goes, we're going to go all the way down to the left side." The team member with the 203 (the grenade attachment for the m16) never shoots, only the 240B (the full assault rifle). (00:06:00)
Continuity mistake: When Solara hijacks the SUV after leaving George and Martha's, there are mountains that disappear from shot to shot. Right after Carnegie yells "Go back," you can see mountains in front of them. When Solara gets out and looks at them turning around, those mountains are gone. After she grabs the grenade and stands in the middle of the road, they are back. When she throws the grenade and Carnegie's vehicle swerves out of the way, the mountains are gone again. (01:27:30)
Continuity mistake: Will Ferrell is in a chair with a blue blanket behind him. The shot moves to the other character and back to him, the blanket is gone. In the next pan it's back. (01:44:00)
Continuity mistake: When the movie starts with the guys filming a video, the position of the rifle in the guy's hands is inconsistent in every single angle.
Continuity mistake: When Abby slaughters the bullies, we see most of the scene from Owen's underwater point of view. First, a decapitated head floats down, leaving a trail of blood. Then, more dismembered bodies splash into the water. We get the sense that the pool water around Owen should be pretty bloody. Yet, when he surfaces, the water around him is completely clear, with no evidence of any blood or bodies.
Continuity mistake: When Becky is having lunch in the park with her workmates, they all turn to look at Adam and the blonde workmate is holding her drink in the air. In the next shot, however, the drink is flat on the table, with no time to change.
Continuity mistake: In the scene where Cindy is about to have her abortion, we see a shot of the nurse holding her hand and the nurse has on purple latex gloves. In the next shot, the nurse is holding her hand without gloves.
Continuity mistake: When they jump on the train at the end of the film, the train tail light is on the right hand side and its also a light that didn't come in until the 80's and in the long shot of the train speeding along the tail light is on the left hand side.
Continuity mistake: When Marie dinners with Didier for the last time, the girl behind has either her hands on the table or grabbing the menu, depending on the angle.
Continuity mistake: First when Carson kisses Rachel she's on his left side. When the kiss is over she's suddenly on his right side. (00:52:00)
Continuity mistake: Towards the end of the movie, after Boyka gets out of the car with the briefcase, Turbo gets out after him and has a conversation. When Turbo goes back to the car, you see Boyka standing on the side of the road. There is only that one road in all the shots. In the next close up shot of the car door closing, and the car moving, we see the car getting out on to the road from a small by-lane (of sorts)! Where did this road come from? How did the car move places?
Continuity mistake: When Jules and Nic are in bed, about to watch a porn movie, Nic's chin rests on her arm or is away from it, depending on the angle.
Continuity mistake: When Stern is cutting Gutterman loose and they're at Rachel's desk, Gutterman is right behind Stern, close enough to touch the desk and sets his hat on it. The shot changes and Gutterman is now further away, not even in arm's reach of the desk.
Continuity mistake: When the two young lads jump off the bridge to escape in handcuffs, as they fall together the handcuffs disappear. (01:12:00 - 01:13:00)
Continuity mistake: At the end of the film, Johnny is shown driving onto the freeway northbound from Hollywood, then shows him in Calabasas, and then Thousand Oaks. That route takes him in a westbound direction, however, the section of freeway he's on in Calabasas is going eastbound (not westbound like he should be). Next, in Thousand Oaks, he's properly going westbound again.
