Audio problem: When Chris and Cynthia are hiding in the little shed from the zombies, there was a scene where a zombie grabs Cynthia and pulls her outside the shed. As she is being pulled out she reaches out to Chris and screams "Brad, Brad" a few times. Brad was her boyfriend whom they killed a few scenes before. But she was with Chris and not Brad so she should have called for Chris instead of Brad.
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: When Andi is knocked out by the oxygen tank, Max seems to be yelling as if he's in slow motion, and yet he isn't. Just because he's weightless doesn't mean he can't talk (or yell) normally within his spacesuit.
