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 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 Tina is in the car with who she thinks is her boyfriend but is really Michael Myers; watch her lips when she says the line "Nothing Mike, that's what I get, Nothing." It is obvious that this line was dubbed in over something else as her lips do not match that particular line. (00:42:55)
Audio problem: From a side view, when Alice yells "Come on Jacob, it's time to go home" her jaw moves to other words. (01:13:10)
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: When Turner is playing with Hooch in his living room, Hooch is chasing Turner and barking at him. However, the audio of the barking is way out of sync with any movements of Hooch's mouth.

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: The auctioneer says the object that Oliver is bidding on is Japanese, but the insert angle of the brochure said it was Chinese. It could be a character mistake, but that wouldn't move the plot anywhere and, besides, this is a movie, so the one who designed the brochure most probably didn't know what the script said.
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.
