Audio problem: In the scene at Willard Whyte's house where Thumper and Bambi are fighting Bond, Bond gets thrown into 3 cylindrical statues. Just as the shot cuts, you can see the last column beginning to topple but there is no sound as it crashes to the floor in the next shot.
Audio problem: As Popeye Doyle is chasing the elevated train, he is continually honking his car's horn to warn pedestrians and whoever else to get out of his way. One scene shows him with one hand firmly on the wheel, and he hits the top-most rim of the wheel in frustration, and the horn honks on both hits. That car did not have a rim-blow type horn mechanism - only Fords had those, and this was a Pontiac Le Mans.
Audio problem: When Harry shoots Scorpio in the leg on the football field, as he walks towards him, Scorpio shouts out "Don't do anything more! No! No!" If you look at Scorpio's face, however, you can see his mouth is not moving in sync with what he is saying.
Audio problem: When Michael kills the sharpshooter in the bell-tower, the man is clearly dead when he falls out of the tower, but we can hear him scream on the way down to the ground.
