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. (00:46:00)

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."

Audio problem: When the three die-hard Indian's fans are arguing over the ball that gets hit out of the park (a guy is saying "It's too high"), one of the guys says "Who gives a s***, it's gone". If you look closely at his lips, he is saying something entirely different. (00:38:00)

Audio problem: In the scene where Matthew Broderick is addressing the potential members of the 54th on horseback (right after he accepts the position), the army band is playing, but the visuals don't match the music.

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: The first time all friends are in the bedroom together Charlie says "Unless you're a genius like Meeks." Meeks replies "He flatters me so I'll help him with Latin." Halfway through this sentence the shot changes to a sideway shot of meek and his mouth isn't moving.
Audio problem: In one scene Miss Daisy is listening to the radio, but the HiFi sound isn't exactly what a small radio in the early 50's was able to deliver. (00:33:40)
