Goofs

During the sequence where Snake is being chased by the Crazies (and is about to shoot an oval pattern in a wall so he can break through), his eye patch shifts enough to reveal a perfectly good eye. This is commonly regarded as a mistake, but it is not; the novelization of the movie explains that Snake still has his left eye, but he wears the patch due to a paralyzed iris, making it extremely sensitive to light.
