Audio problem: In the scene where Leo explains how he launders the drug money and Roger says "You're a cheat", Leo says "Come on, everyone cheats a little, look at the pentagon." But when he says "look at the pentagon", it's dubbed in because the sound of his voice doesn't match his other dialogue, and if you read his lips it doesn't match either.
Audio problem: When Indy confronts the butler at the castle, we hear the butler say, "If you are a Scottish lord then I am Mickey Mouse." But his lips say something else. He actually said "then I am Jesse Owens." This line was changed because they thought that a lot of the audience wouldn't know who Jesse Owens (the black athlete who won at the Berlin Olympics) was.

Audio problem: When Doc and Marty return to the year 1955, you hear the squealing sound of tyres braking heavily, but the DeLorean is flying. (01:02:25)
Audio problem: When the crew are running around the passages, a guy with a beard yells something at Bud, and then uses a fire hydrant to put out a small fire. Funny, it doesn't make a noise.
Audio problem: After throwing what looks like a toilet through the window, the two guys give each other a high-five. Their hands almost completely miss each other, yet we still hear a loud clap.

Audio problem: When Tango and Cash first meet the Assistant Warden, somebody dubs over his voice and the words don't match his movement - and it is very obvious that it is not his voice. (00:45:00)
Audio problem: Unlike the second movie, the jet engine sound was not dubbed over the piston engine sound. The fact is, the jet engine in the Batmobile is a fake.
Audio problem: When Dooley is in the car on stakeout, he is playing on a Nintendo Game & Watch. They were only capable of bleeps and buzzing noises, yet this one has a sampled laugh, which was never possible on these handheld games. (00:02:20 - 00:10:55)
Audio problem: Dana shows up at Peter's door with poor little Oscar desperately crying after the bathtub misadventures. Is he really crying though? Sigourney Weaver does her best to hold the baby close to her and away from the camera, that shoots the scene cutting off above the mouth level. His body language is composed though, and for one moment (when Dana says "this pink goo everywhere" his mouth pops in frame and it is closed. (00:46:20)
Audio problem: When Mylee begins to berate Kurt for causing a mess at her store, her lips do not move. (00:36:10)
Audio problem: When Angela is using the turret to eliminate the soldiers who have just arrived at the airfield in the truck, you can see for a moment that the gun stops firing and producing flames. However, you can still hear the turret firing.
Audio problem: When Bond takes the 'belt' off his tux, in order to get the concealed rope, there is a scratching sound, as velcro ripping. But the belt is not closed with velcro. We can see metal clamps when the belt lies on the ground and Bond removes the rope.
Audio problem: When the Enterprise fire the torpedo, the sound used is the old series sound used when the ship's phasers were fired, not the correct noise for a torpedo firing.
