Continuity mistake: The favorite family restaurant is "Enzo's" and that is the name in neon at the place. But during the confrontation with Nick and Mary in the car (in the rain) Nick says to never go back to "Sorento's." My guess is that they changed the name after filming the scene. (01:05:20)
Continuity mistake: When singing the song about what they would do if the monster came to their room in the night, Simon puts on Alvin's duvet/blanket as a cape. It then shows an imagination sequence where the blanket is a correctly sized cape to fit him. When it returns to the real world, the 'cape' is the size of his imaginary cape, nowhere near the size of the bed.

Then about two minutes later, when Ed starts the contest you see another shot of her but she's now wearing different clothes, green dungarees and a grey jacket. Then later on just before Edtv is cut off, she's wearing different clothes again. Why would she change three times in one day? (01:43:05 - 01:47:15)
Continuity mistake: When Zach is talking to Mackenzie about Laney (right after it shows Brock farting on 'The Real World'), there are two shots. In the first, Mackenzie puts cream in her hair, and right away there's another shot but it shows her putting her eye makeup on. She couldn't have finished putting the cream in her hair so fast. (00:14:35)

Continuity mistake: In the shot where Cora and Ellen are in the car going to the beach, the blue car is a left-hand drive, as Cora is driving nearest the camera. However, in the rest of the film, it is a right-hand drive, such as in the shot returning from the beach. Cora is still nearest the camera, but they are travelling in the opposite direction. (00:45:22)
Continuity mistake: When Woody Harrelson and Antonio Banderas are fighting, Antonio's character is knocked down and his cornerman calls him Vince, not Cesar.
Continuity mistake: When Ben Jordan and Stan are walking around the fountain, they walk past a long glass railing. The white sneakers of the cameraman can be seen in the reflection on the glass. You know it's him because he stops walking when they stop and continues walking when they do.
Continuity mistake: After Jamie Fox gives his line about how the blond policeman should be tried for attempted murder, it shows three quick shots of him. The first one is a wide angle of him and the sheriff. The blond cop is wearing a hat and sunglasses. It then shows an up close shot of him without the hat or sunglasses. Then it shows the wide angle again and he's wearing the hat and glasses again.
Continuity mistake: In the scene where Alicia comes out of the bathroom at the drive-up restaurant and seduces Brad, throughout the scene a piece of Brad's hair goes from being on his face to being fixed.

Continuity mistake: When Miss Hannigan, Rooster and Lily are singing "Easy Street" outside in the street, Miss Hannigan beats her fur shawl on the ground, and a large piece of fur falls off it. In the next shot, this piece isn't lying on the ground anymore. (00:50:55)
Continuity mistake: At the end of the opening credits, Crawford finishes doing the hair of a client and puts his hands on her shoulders. She says "Crawford, you're a genius"; in the wider angle, no hands on her shoulder, and they are back in the following closer view.
Continuity mistake: When Calvin first goes back up to the surface, he encounters the bartender. The bartender is shown as himself moving at first then he freezes while Calvin's light is on him. Again it shows the bartender but you can tell if you look close enough he is just a piece of cardboard falling to the ground. Then Calvin tells the bartender to leave his elevator alone. (00:27:03)
