Factual error: One day the prince accompanies his father to a meeting to solve an upcoming worker strike. This should not be possible, since Denmark's constitutional monarchy has no influence on the workings of the government. (00:11:40)
Revealing mistake: Near the end, when Morgan Spurlock says "Why not do away with your Super Size options?" the water condensation runs UP the drink. (01:34:00)
Visible crew/equipment: When Albert and his friends are in front of Doris' house they are singing a song about going to the park. As they are finishing the song and leaving to go to the park, you can see the reflection of the microphone in the window of Doris' house.
Factual error: In the scene in Costa's apartment after the failed baiting ploy, Costa describes himself as a loner who "bought a gun for a false sense of security", appeared to have had it with him during the evening, and gave the impression that he bought it after he witnessed the murder. Although IlIeana mightn't know, the Montreal police in the room might (should) have wondered about this. Even if legal, it is very difficult to acquire a restricted weapon (handgun) in Canada, the process taking one month to as many as six or more for clearance and permits, let alone courses and examinations. In addition, concealed carry of a weapon is prohibited for civilians. (01:00:25)
Factual error: When Blade notices the piece of Dracula's armour in the Nightstalkers' headquarters he's shown an image of what the full armour looks like. It'd be impossible to extrapolate a full suit of armour from such a small piece.
Other mistake: When Sarah Michelle Gellar is on the bus with her boyfriend, she sees Kayako face looking at her in the window reflection and panics. When she looks back at the window she sees the normal reflection of her face. Trouble is, her reflection is turning her head and looking side to side, whilst Gellar herself is looking straight and not moving her head at all.
Factual error: In the scene where the fireflies light the fireworks there is one problem: The chemical that creates light wouldn't ignite the wick on a firework.
Continuity mistake: In the scene where Mike picks up Deborah, we see a shot of his Audi and there is no licence plate on the front of his car. In the shot we see him driving, it has one.
Audio problem: When the band is singing "You're Out of this World," when one of the band members sings at one part, the music starts before he starts to move his mouth.
Factual error: In the scene that takes place in Ollie's office after the death of his wife, he is talking to Arthur Brickman who is sitting in front of a plaque for the band Songs:Ohia's album, "Ghost Tropic." We know that the scene is happening 7 years in the past, because Gertie is a baby. "Ghost Tropic" wasn't released until November of 2000.
Continuity mistake: At the beginning, Ray holds out a ticket for the bus driver to see. In the next shot, from behind, both Ray's hands are at his side. When the shot changes back to the front, his right hand is extended again holding the ticket.
Continuity mistake: When Gummer and Black Hand Kelly make an agreement, Kelly looks to his left and he isn't holding a glass. When it cuts, he is looking to his right and holding a glass. (00:40:35)
Continuity mistake: When Ricky is in front of the shop talking to his girlfriend, one moment he has his hands out, the next moment he is holding a cigarette and in the next scene, no cigarette.
Revealing mistake: This happens at the end of the movie. When No Good is tenderizing the meat with the brass knuckles, you can see that his hand doesn't come anywhere near the meat.
Continuity mistake: When at the Men's Association, Mike Wellington raises a glass and toasts Stepford. He does this with his left hand. When the shot changes to show all the men, he is still doing it with his left hand. But when the shot changes back to Mike, the glass is now in his right hand, with no time between shots to change hands.
Continuity mistake: During the "Echo game", Jin throws the full bowl at the targets and all of the shells fall on the floor. Yet in all shots afterward, they are nowhere to be seen.
Continuity mistake: In Maggie's first fight (when Frankie isn't her manager), she comes off after the first round and takes her mouthpiece out. After talking to the manager, she gets back up to enter the ring without putting it back in, but when the bell rings she has it in again.
Continuity mistake: When Harold and Kumar stop to take a pee and then leave, Harold gets bitten by a raccoon. In one shot Harold's blood stain is seen on his jacket, but in the next shot it's gone, then back again and so forth, until the car comes to a stop.
Continuity mistake: When Emily is spying on Cody on the sightseeing bus, she sits down and the camera goes to a close up of her face and we see small worm like camera device comes out of the right side of her sunglasses, but when it cuts to the next shot, further back from her face, we can see the device has disappeared even though no time has passed between shots.

Factual error: In 1973, directly after the scene where Sam had to chase the dog down the street, he sits in his apartment alone, watching Julie Nixon's wedding on TV. She was married in 1968.
