Deliberate mistake: When the girls all order their food at the drive through they get their food but never pay. (00:17:15)
Deliberate mistake: The balloon llama the chipmunk makes has legs which are completely detached. The pairs of legs should be twisted together. Without this, it looks like the balloon has 6 different ends.
Deliberate mistake: When Layla is having babies and the first one comes out there is already a nappy on the baby. (00:06:45)
Deliberate mistake: Elizabeth Shue uses a drawer handle as an electromagnet. OK if it's really a magnetic material but lab furniture is generally made of aluminium or stainless steel which is not. There is no way that they would use an iron handle in a potentially wet, and hence corrosive, environment such as a freezer.tw_stuart
Deliberate mistake: You might be wondering where Terry suddenly comes up with Jolly Jack all of the sudden after escaping the lab. In the commentary, they say that the Joker, in his transmission to Terry in the lab, was supposed to be eating out of a candy jar with "Jolly Jack" on it, but couldn't have it due to time constraints.
Deliberate mistake: When Reinaldo is narrating right after the police begin to crack down on the gay movement in Havana, he speaks of "sex as a weapon against the regimen". Shouldn't it be the regime? (00:44:20)
Deliberate mistake: When Greg gets murdered and Cindy, Bobby, and Buffy are trying to figure out what happened, you can see the killer is mopping up the blood. However the floor is carpeted so the blood wouldn't clean up, it would smear instead. (00:31:20)
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.
Deliberate mistake: In chapter 15 "Bad Service" as Kim drives away and almost hits the kids which are supposed to represent the "Burkittsville 7", count them. There are three girls and four boys. Rustin Parr kidnapped 8 kids; 4 boys and 4 girls. Kyle Brody survived so the Burkittsville 7 should be 4 girls and 3 boys.
Deliberate mistake: When the limo driven by Gwen (Sandra Bullock) runs over the white picket fencing it's not Sandra's face behind the wheel in the exterior shots. Also, when Gwen runs over the short white picket fencing, in the interior shot from the car the corner of an 'L' shape fence is being hit, then in the front exterior shot the end of a smaller fence is hit. This is cut from a longer sequence, the smaller fencing is seen way in the distance in the first shot. (00:07:45)Super Grover
Deliberate mistake: When Carlo and Bonehead go upstairs to confront Jack at the hotel, Bonehead accidentally shoots Carlo in the leg and Carlo fires eight shots in retaliation at Bonehead killing him. Carlo immediately bursts into Jack's room same gun drawn. When Jack jumps out the window Carlo begins firing and shoots another 15 times. There is no way the single clip in the gun Carlo uses could possibly fire 23 rounds.
Deliberate mistake: In the scene with all the coffins and new Skull "recruits", Lucas knocks on the unopened coffin and Caleb pops up. The next shot is a wider shot that shows everyone standing around Caleb's coffin, but the guy in the coffin is not the actor playing Caleb, but a stand-in.
Deliberate mistake: The Americans actually spoke with American accents, but these very new Americans were British in origin, and so they couldn't develop a new accent in such a short time. The Americans should still have British accents. This would have been confusing and is done for the viewer's benefit, but still a mistake.
