Audio problem: At the end of the fight when Apollo tells Rocky there won't be a rematch, his lips aren't moving. Rocky's lips aren't moving either when he says "Don't want one!"
Audio problem: After Turner tells his son Joey to throw to Engleberg low and outside, Joey replies "But Dad - I wanted to strike him out", however his mouth doesn't move at all and the volume on this line is much louder, so obviously dubbed in.
