Continuity mistake: When everyone is in the Library, you can see the matches in a cup on the left of the fireplace. When Professor Plum says, "Wait a minute, suppose that one of us is the murderer," you can also see that the matches are in a "V" shape. When Wadsworth walks towards them to pull the matches out, most of them are all leaning to the left side of the cup. As the movie goes on, when the cop gets locked up in the Library for the second time, the same amount of matches are in the holding cup as if Wadsworth did not pull them out and they are in a straight line. (Third time code 1:02:40). (00:44:25 - 00:45:05)
Continuity mistake: When Amanda and Daniel entered the bathroom from 'Saw', Adam's body is shown with his right leg shackled. However, in 'Saw' and in Adam's death flashback in 'Saw III', his left leg is shackled. (01:14:10)
Continuity mistake: In the scene at the apartment with Brett, Vincent closes the briefcase and leaves it on the kitchen counter. He continues to smoke until it's almost time to shoot Brett. They shoot Brett and the scene fades out to be continued later. Later we see that after shooting Brett, Vincent is focused on Marvin still in the corner having a panic attack. Jules tells Marvin to knock it off and the man comes out of the bathroom. Jules and Vincent shoot him, then Vincent chides Marvin for not telling them there was someone in the bathroom. Vincent only has his gun in his hand, no briefcase. Jules and Vincent argue about 'the miracle' and they leave. Marvin never leaves the corner until Jules tells him 'let's go'. Nobody has the briefcase. (00:18:10 - 01:53:30)
Continuity mistake: After Ken reverses the steamroller after running Otto over with it, you can see a red patch signifying his splattered body in front of the roller. However, a few scenes later, Otto is seen alive. (Otto was originally meant to die, until test audience feedback influenced a change of mind on the part of the filmmakers.)
Continuity mistake: Steve McQueen passes the same green Volkswagen at least three times while chasing the black Dodge Charger R/T. This is due to the same downhill portion being shown to us from multiple angles to artificially extend the length of the scene.
Continuity mistake: When they are in the Whitehouse, and Beavis has turned into Cornholio, he picks up the "Red" hotline phone on the President's desk, and is talking to the nuclear bomb officials. Later, when they are in the President's office again, getting their certificates, there is now a black phone on the desk, where the red one was. (01:03:05 - 01:11:00)
Continuity mistake: When Hutch tackles Starsky to the ground after his gun goes off in the disco, Starsky's badge falls to the ground beside his head. Hutch grabs it and holds it up, telling people to calm down, but when the shot returns to Starsky the badge is still there next to his head. (00:49:40)
Continuity mistake: When Ghostface is trying to kill Tatum in the garage, she tries to go through the doggie door. From the outside shot, she is out of the door from her arms and up. From the inside shot, she is out of the door from her hips and up. (01:04:20)
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: During the interrogation scene, when Batman beats up Joker, Joker's hands are holding Batman's forearms upside down (from underneath). When the frame changes his hands are now on top of Batman's forearms, then it cuts back and his hands are under again. (01:28:00 - 01:29:00)

Continuity mistake: When Sly is in the attic, and the fake power dude comes up to kidnap him, Sly uses a ski to "hit him in the gonads". But if you look closely at his face, the guy who was hit in the nuts wasn't the same guy that fell down the stairs.
Continuity mistake: When they are in the car with heavy rain, you can see the pedestrians are NOT using umbrellas or wearing raincoats. It’s also raining far harder on the left of the car than the right. In addition, Somerset is turning the wheel to the right, and yet they’re driving in a straight line. (00:12:10)
