Audio problem: The sounds of the weapons being used in the movie are evidently inserted in most cases. Like 1) When MacLeod fights Fasil in the Madison Square Garden garage, he uses an iron bar to ward off the sword blows - the twin sounds in both impacts are exactly the same, but in the second instance, the bar is hit only once. 2) When MacLeod and Brenda are ambushed by Kurgan, MacLeod swings a cable or chain at Kurgan. The sounds are exactly like those of the swinging swords.
Audio problem: After Connor and Brenda's sex scene, we see them in a zoo in front of a lion cage. After his line : "I can't get involved, not again", we see Brenda talking back to him but nothing is heard. (01:36:33)
Audio problem: On the roof of Silvercup Studios at the end, Brenda is screaming, but her lips don't match the screams.
Audio problem: The bad guy (Kurgan) stabs a thug and raises him in the air. During this scene the guy stabbed is making noises, including the word "what", however his mouth doesn't match up with what he is mumbling.
