Continuity mistake: Near the beginning of the movie when Alexis is getting ready for her first date with Tank, her roommate is holding a cheetah print shirt. The shot changes and suddenly Alexis is wearing it, even though she has not had time to put it on. She is also holding a drink in her hand, but she never puts it down. (Although this is explained on the DVD's Deleted Scenes, it is still a mistake.)
Visible crew/equipment: When Brother Silence/Cass leaves the house after finishing the campaign at the end of the movie, he opens the front door to leave and there is a glass door/screen there outside the house. For a second you can see a crew member holding the boom mike in the reflection of the glass door. (01:28:10)
Character mistake: When Massie reads the IM from Kristen, she doesn't look at the past messages. Claire didn't delete the messages from the past.
Continuity mistake: In the scene where Larry The Cable Guy is eating a long dog while talking to Madeleine, he keeps biting down on the bun, yet the eaten part reappears. This happens twice during this scene.
Revealing mistake: The raid took place at Xmas in 1951. In homage to this fact, the characters wear big coats and one of them even rubs his hands together and goes "Brrr." Yet the movie was filmed in the height of summer. Trees in the background of scenes in London are full of leaves, we never see any mist in exhaled breath and the lighting levels and shadows indicate a high, bright sun.
Continuity mistake: When the brothers are standing on the rocks on the beach, the clouds change back and forth behind Stephan.
Continuity mistake: Addington and his manager talk about showing Zarno the "Under the Sun" sticker idea to make money. Trouble is he would already be getting royalties from it. Two scenes earlier, April May meets up with Add wearing an "Under the Sun" T-shirt. Therefore he was already making money and didn't need to go see Zarno.
Visible crew/equipment: When Tibby is talking to Lena on the phone about the man in her art classroom, you can see a crew member's face reflected on the glass window.
Factual error: The bar shown in Iqualuit is not real. Iqualuit only has 6100 or so people, and there is no bar like the one shown in the movie. The building is wrong - it doesn't even look like any buildings in Iqualuit. There is one bar that looks nothing like the movie, one Legion, and a bar in the hotel in Iqualuit.
Character mistake: Throughout the movie, all of the drill sergeants and First Sergeant Morley are wearing their drill sergeant badges too low. The badge is supposed to be centered on the right jacket pocket.
Continuity mistake: When Despereaux fights the cat in the rat arena, he hides behind a blue ball of yarn. When the cat hits the yarn, causing Despereaux and the yarn to fly in the air, in the next shot, the ball of yarn vanishes and never reappears again.
Continuity mistake: Jim, driving Scott home, is smoking a cigarette that disappears before he slaps Scott the second time. There is no smoke in the vehicle that would suggest Jim temporarily placed the cigarette in the ashtray. (00:15:09)
Continuity mistake: During the scene that Bo and Sam kiss, his hair changes between shots. From the back, his hair is completely pulled back. From the front, his bangs are down. (01:27:20)
Continuity mistake: When Annie is taken to the truck (in Mexico), she has no coat on and a gag in her mouth. When they reach the cantina, she is taken out of the truck wearing a brown jacket and no gag, but as soon as they show her inside the cantina, she once again has on no coat and is gagged.
Visible crew/equipment: When Yu and his friends have finished dragging Yoko into the van, Yu jumps into the van and closes the door behind him. When he finishes closing the door, the reflection of the boom mic can be seen in the window. (02:44:50)
Continuity mistake: While Michael Malone and Gen. Patton are discussing what just happened in the subway, in the background, two ACLU zombie-lawyers begin chasing an ambulance as it drives away. After a brief cut away, we return to the same view - and the same zombie-lawyers chasing the same ambulance.
Continuity mistake: Some of Aunt Jillian's bangs (parted down the middle) were separated from the left side, partially covering her eye when she went into Chris and Nicole's house but the gap was gone when the camera shifted, and she was walking toward them. Aunt Jillian had "The Goonies" in one hand and a bag of Dunkin' Donuts in the other, so didn't move her hair forward to close the gap. (00:17:23)
Continuity mistake: When Justin gets his sex toy home, he turns his family photo facing down on his nightstand. He turns the photo down square with the nightstand. The next cut, the photo is turned 45 degrees to the nightstand. (00:14:10)
Continuity mistake: In the scene where the drama teacher is in the copy shop trying to decide what color paper to buy, his hand keeps moving between shots. Every time the shot is from the copy shop side of the counter, the drama teacher's right hand is in front of the blue paper. But every time the shot is from the drama teacher's side of the counter, his right hand is in front of the orange paper.
Revealing mistake: In the opening scene, when Van Damme kicks an opponent onto the boot of a London Taxi Cab, you can see the dent from previous takes.
