Trivia: Peter Barton was hesitant when it came time to do his death scene, as he was previously burned by a magnesium flare doing a stunt on a previous film and required multiple surgeries afterwards. Sensing Peter's hesitation, Ted White requested that a pad be placed behind Peter's head when he was slammed into the shower wall.
