Continuity mistake: When Christine gets out of the shower at Cotton's apartment she has dried off, stood and walked on the carpet, and put on a nightie. When the stereo starts blasting and she walks down the hardwood floored hallway her feet leave very wet footprints which she slips in later when the killer chases her back up the hallway.
Trivia: Just to alert those not in the know - if you were in the audience and were entirely confused when two characters dressed in black appeared, the tall skinny one says something to Gale, and half the people around you laughed, you clearly haven't watched enough good films. Those characters are Jay and Silent Bob from Clerks, Mallrats, Chasing Amy, and Dogma - four fantastic films from Kevin Smith, who plays Silent Bob. Go and see them. Now.Jon Sandys
