Continuity mistake: When Jeffrey is on the phone, he is holding the phone by his ear in the front view, while in the shot of his back there is no phone by his ear.
Continuity mistake: After the gunfight Redmond talks about girls, etc. The guy he talks to crashes his can of beer with his right hand in one shot of Redmond but when in another shot the can ends up in his left hand.
Revealing mistake: Towards the end of the film when the Yankees are trying to close out Game 6 of the World Series you can tell the "real" footage they use is not from the World Series. They are playing the Atlanta Braves in the World Series but you can see the Baltimore Orioles logo on the field in a number of shots.
Continuity mistake: In 4th black's move, king's bishop go to third row (A3) and capture the white knight. There is not elipsis yet, but. in 6th black's move, Geri's imaginary opponent takes a piece from A4 to B3 and capture a white pawn. but there wasn't any piece previously on A4, in fact, pawn was not moved before, staying on B2, its original place. In the next shot black bishop remains on A3 and white pawn on B2, as nothing was happened.
Continuity mistake: As Prince Valiant observes the Black Knight's meeting with the vikings on the beach, the knight's visor changes position from shot to shot. When shown from behind, his visor is up, which would reveal his face. But when the knight is shown from the front, his visor is down to conceal his identity. (00:11:05)
Revealing mistake: Johnny Depp is at the house of the pimp guy who assaulted his wife. They have a fight, and Johnny kills the pimp but he is clearly breathing when he is supposed to be dead.
Continuity mistake: In the scene where the cop car is over taking the runaway car you can see the front bumper of the runaway car and it's in perfect condition however earlier you see them take it off. in the next shot its back to normal.

Continuity mistake: The rich promoter has red on his vest, before Don King throws his tomato juice.
Audio problem: When Mitchell Stephens goes to the Otto's, Hartley offers him some tea just as the teakettle comes to a boil and starts whistling. Unfortunately, the kettle shown on the stove was the normal, non-whistling kind.
Continuity mistake: In the scene where Tia Carerra is reborn. Her deformed servant is chanting a spell and places a flaming dagger in her mummified mouth. She awakens and bursts into flames, just then she touches his badly deformed right hand and it heals. Over the next few camera shots his hand goes back and forth from normal to deformed.
Factual error: At one point late in the film, Terry says she called in a favor to the "District Attorney" after Lim was arrested. In Chicago, where the film is set and where the arrest took place, there are State's Attorneys, not District Attorneys. Terry, a lawyer practicing in Chicago, would most definitely have known that.
Continuity mistake: When Amy is standing in front of the fire in the cave and her dress catches fire, she turns 180 degrees to face Yanko who comes into the cave. The camera cuts to her dress, and her feet are now pointing towards the fire, before she turns around once again.
Continuity mistake: Throughout the movie, the stallion constantly changes from being a dapple grey horse to a flea-bitten grey horse.

Visible crew/equipment: When Perdita is fighting in the desert, the sun is creating a shadow of the whole crew that can be seen at the bottom of the screen.
Revealing mistake: The background scenery in the outdoor shots doesn't look anything like Illinois, where the movie's supposed to be set. It's much more like what you'd see in California - where the actual filming took place.
Factual error: In one shot, the camera is on the platform at Tottenham Court Road station, and a sparkling new train rushes in. Wrong type of train - the one used is from the semiautomatic Victoria Line stock. I suppose London Transport must have been too ashamed of their Central and Northern line trains to have allowed them to be filmed.
Continuity mistake: When Danielle is in the evening gown section in the Miss Madison competition, her dress changes from sky blue to sparkly dark blue after the shot cuts to her mother.
