Audio problem: When Ponsonby is being pursued by the Polish Lancers across the muddy field, he gives his watch and snuff box to the young bugler and tells him to ride on and save himself. However, his lips do not correspond to the words.
Audio problem: After the scene with the white dude visiting Sanford to look for cotton, we see the reverend being greeted by a bunch of people playing billiards. There's a marked discontinuity even in the audio played as he walks forward to a hi-five, not to mention that nobody had the cue anywhere near the green carpet but still you see in the second shot that balls are rolling.

Audio problem: When Zira and Cornelius return home discussing stuff, Zira begins making chocolate icing. As she makes the icing, she says "Gorillas are cruel because they're stupid." When she says "stupid", her lips never purse together on the "p" but that doesn't stop her from being able to say "stupid." (00:24:15)
