Audio problem: There is a clear lip-sync problem in the boat scene, after Eugene takes out the lanterns.
Audio problem: In the very first scene of the movie when Bobby is recreating his performance at the Coconut Grove, the actions of the band are out of sync with the music we hear. (Bobby is in sync, but the band is not.) Watch the hands of the drummer and the band leader: The entire scene is out of sync, but when the drummer moves to the ride cymbal you can easily see he is ahead of the music, and when the band leader gives the band cues for accents, his hand movements are behind the music and therefore happen too late.
Audio problem: At the beginning of the fight at Rough House's, after Popeye says "Enough is enough", it looks like he elbows the two nearest guys. If you look closely, they react a split second before the elbows get them, and the sound completes the illusion. Also, the last guy Popeye is punching in the face is moving just out of sync with the punches. The sound is like a punching bag, but his head is recoiling just a split second out of time.
Audio problem: In the last scene when Vlad, Michael and Ellen are swimming, Michael is talking as he enters the water. His head dips under water, but you can still hear his words.
Audio problem: During the Second Chances song, when the 1st female singer sings the words "Second chances!" her voice is that of the 2nd female singer. (00:50:45)
Audio problem: When Davey is burping in the china restaurant and all those people's glasses break, you can hear the glass break at least 1 1/2 seconds before any glass actually breaks.
Audio problem: Throughout the opening song "Shiver My Timbers," the puppet's mouth movements don't match what they are singing.
Audio problem: When Warren T. Rat calls open season on Fievel, the cats all scramble at once to capture him. In one shot where Fievel is running from either end of the piano, he jumps upon the same key twice. The notes play, but the key never goes down at all. (00:51:55)
Audio problem: While Bing Crosby sings "White Christmas," he is playing the piano. However, the piano is never heard.
Audio problem: After Chico and Harpo first meet there's a man at the opera playing a drum. Not only is he out of sync with the sound we hear, but he is mimicking the blows.
Audio problem: While Judy Garland is singing in the bar and Fred Astaire spots her, the trombone backing up Judy Garland is playing, and suddenly the trombone sound goes from open to the sound of a muted trombone. However, the actor continues playing it unmuted. He should have a cup mute in his horn at this point. (00:18:19 - 00:19:38)
Audio problem: While Thomas O'Malley is saying "all right now, don't panic" his mouth is not moving.
