Audio problem: Ness grabs a man who's trying to blackmail him and throws him out of the office. When he does, his voice changes abruptly, much cleaner, obviously overdubbed, and the sentence "You tell Capone that I'll see him in hell" is heard but Ness doesn't mouth it.

Audio problem: In the beginning, when Murtaugh's daughter comes downstairs in the black dress the dialog is dubbed in. After the spin, she's talking but she doesn't move her mouth (even before the spin she isn't in sync). Her little sister replies and doesn't move her mouth either.
