Audio problem: When Dade is typing on Kate's computer at the party and she is leaning over her shoulder, we hear "I hope you don't screw like you type", but Kate doesn't actually say 'screw', she mouths a certain 4-letter word that starts with F.
Audio problem: When Judge Dread and Rob Schneider are running to escape from oncoming guards they are stopped by one guard right before they leave on the motorcycle. The guard says "I knew it was you Dredd." The camera focuses on him before he is done saying that but his mouth is not moving.
Audio problem: In the beginning of the film, Sly is on the computer telling his employers that the mark has been retired. If you listen to the keyboard strokes compared to what's typed on the screen, you'll notice that no sound is made for the space bar or the enter button.
Audio problem: When boiling acid starts spraying inside of the bank vault that Batman and a security guard are in, the security guard shouts "It's boiling acid." But his lips does not match with what he is saying. It happens again when the guard yells to Batman, "Don't let go." (00:08:15)
Audio problem: In the scene where Sharon Stone is talking to Joe Pesci about how De Niro had his guys beat up James Woods, at one point Sharon Stone says, "Oh C'mon." If you look closely her mouth doesn't move at all. Also if you listen closely, that line comes out on surround sound. When she continues her line it comes out on mono. It was obviously recorded.
Audio problem: When the other prostitute is run down, in the ensuing crowd chaos you hear a man scream 'Hey you jerk,' or words to that effect. Several seconds later you hear the same shout again, the exact phrase, the exact tone, the same recording.
Audio problem: When Mike and Marcus are driving in Marcus's car, just before they sing Bad Boys, in the shot over Mike's shoulder we see that what he is saying does not match the movement of his mouth. (00:22:40)
Suggested correction: But Will Smith is not speaking in that shot. Martin Lawrence is saying something corny ("I'm a baaad boy") that is the cue for the song. Smith is just mouthing under his breath.
Audio problem: At the beginning of the show when MJ and Reuben are introduced in the training area. Reuben fires his handgun but the sound does not match the shots.
Audio problem: In the club in which Nancy is dancing (and Keung goes to talk to her), there is dance music playing. This is not a score to the film/scene, but rather an actual song being played in the club. Then why is there also a rock band playing guitars/bass/drums, and why can't we hear it? It's also quite obvious that the band isn't playing in harmony with that dance song in any form, either.
Audio problem: In the shots of Detective John Mackey standing by the window looking out of the blinds at Selena, while he's on the telephone, as he speaks, nothing that we hear matches up with the movements of the side of his mouth. It is very clearly out of sync, and audio is heard when the mouth is still. (00:07:55)
Audio problem: The guitarists weren't going with the sound of drumming on their guitars. Also the timing of their lips while singing were wrong.
Audio problem: In the opening scene, where Johnny and Kamal are arrested and they're making their way to the police station with the cops, notice the cop screaming, the words don't match his mouth.
Audio problem: When Lenny, Masey and Max have found Tic "cooked off" in his van, Masey and Max are having a discussion and there is a shot of Lenny in the van, trying to make Tic more comfortable. Behind him, you can see Masey and she is obviously talking, but unfortunately, it is Max we can hear in voiceover.
Audio problem: During the heist in the Federal Reserve a lot of sounds are missing. For example, when Katya drops her bolt cutters, there is no sound as they hit the ground.
Audio problem: After the Gluttony murder, both detectives drive to the forensic and have a chat. The audio is slightly out of sync with their lips. Spanish DVD release. Fixed in the Blu-Ray edition.
Audio problem: When Max tells Fishman to get the hell out of here, his lips don't move.
