Continuity mistake: As Dalton stands inside the bank vault staring at the cash, the scene jumps from a wide, distant shot, to medium, to close-in, just outside the cage. Another robber stands just outside and between jumps his gun position shifts from relaxed to raised to relaxed again.
Suggested correction: Whilst this is true, I don't think it is a continuity mistake. It looks to me like it is intended to suggest the passage of time between each of the three shots.
Continuity mistake: Watch the newspapers on the front of the bus when Mos Def is getting off. At one point there is a big hole and you can see out, but in the very next shot a newspaper is covering it again.
Continuity mistake: When Clouseau parks in front of the ministry of justice, he breaks the hood of two police cars. A few shots later, when we see him entering the building, only one of the cars is broken.
Continuity mistake: Just before Amanda shoots Lynn her gun switches from her right hand to her left.
Continuity mistake: There's a scene with a woman dead on the floor, in most of it her left hand is down and her right is at her mouth. But, in the last shot where she is seen, her left hand is at her mouth and her right is lying out away from her head.
Continuity mistake: When Ellerby attacks the guy for not installing the cameras in the right place, he knocks off a map from the board. A second later Ellerby is still going after him, and the map is fixed.
Continuity mistake: The inside of the plane to Japan is a Boeing 747, but outside it's a 737. (00:11:40)
Continuity mistake: In the fight scene at the party, Jake gets hit over the head with a bottle and he has blood on the top of his head. It changes constantly throughout the fight. It disappears totally when the fight is over. He has no blood anywhere on his body.
Continuity mistake: The cookie Calvin rubs all over his body only has raisins on the top left of the cookie. When the grandfather picks it up they are neatly in the center: not the same cookie.
Continuity mistake: When Ryan Reynolds is between the two hospital beds, preparing to pull the plugs, there are three wires he grabs to our left (two white and one black). He yanks all of them out (along with another white one to our right) and no plugs remain in the red outlet cover on the wall. But in close ups, as the other agents are banging on the door, we see the lone black wire is still plugged in. (01:40:15)
Continuity mistake: In the morgue scene, the coroner states that Elizabeth Short had a wound inflicted on her right hand, but then in the pornography scene, she grips the bed post with her left hand.
Continuity mistake: When all of the dancers are preparing for the showcase dance, Nora walks in with hair that has her usual bounce. When she and Lucy are talking in front of the mirror, her hair is almost completely straight, sporting just a few slight waves. When Tyler approaches her backstage, her hair is extra curly. It has only been a few minutes, and there was not enough time for her to have curled it. This is confirmed in the commentary.
Continuity mistake: In the scene on the roof after the power transfer, Hannah falls through the sky light and Matt yells down to her. You can tell the close-ups on Matt were re-shot because Matt's hair is longer and styled differently in between shots.
Continuity mistake: When Felicia and Brenda run into Lorraine behind the Armstrong homes, Lorraine pushes between them and walks a few steps. In the next shot, when she turns to say, "You stay away from my child," she is suddenly in Brenda's face, but in the following shot she is about ten feet away when she resumes walking. (00:48:30)
Continuity mistake: When Slevin is in Nick's apartment the second time, eating the sandwich, the way he holds it changes between shots.
Continuity mistake: In the garage scene, 02 pulls a pistol from the guy he beat to the floor and stuffs it into his pants quickly as his girl starts trying to kick the guy on the floor. when he stuffed the pistol into his pants the grip was pointing to his right pocket. With the quick struggle the shot changes back to the pistol in his pants and now the grip is pointing towards his left pocket, and no one touched it.
Continuity mistake: The crescent-shaped scar which bisects the protagonist's right eyebrow in many scenes appears instead on the left eyebrow in many others. Same size and shape, but looking as if photo-reversed; for instance, when his face appears from the darkness to sniff over the shoulder of the red-haired girl, the scar is in the right eye-brow. But during the scene in the plaza before a huge crowd (the hanging scene) the scar is over his left eye.
Continuity mistake: At the very beginning of the movie, when Kim Basinger is in the bedroom and walking towards the mirror, the movements of her reflection do not match her movements. She stops moving and her reflection continues to move. (00:04:25)
Continuity mistake: In the scene where the guy and the girl are making out on the bed, they trigger a bell to ring in Kane's lair. The bell shown ringing is a large bell on the far left top row of two rows of bells. When he walks into the room to see which bell is ringing, the bell ringing is a small bell in the middle of the bottom row and the large bell isn't moving at all. Later in the movie, that same large bell is triggered when the kids are walking down the hall and hit a trip wire, and it makes a completely different sound than the first time.
Continuity mistake: When the guys in the Impalas are chasing Chevy and his girlfriend from the sweatshop, the last car hits the fence. Right before the car hits the fence a guy is hanging out of the window (meaning it's open). After Chevy walks up and finishes the guys off and turns around the angle changes with the car behind him and the window is up. Chevy would have shot it out EVEN IF the guy rolled it up. (01:03:30)
