When the guys enter Carlos' apartment, a member of the crew is plainly visible in the shot. According to the director's commentary, this was not a mistake - director Jean-François Rivard planned this shot as an homage to the character Killer BOB from the TV series Twin Peaks. Killer BOB originated as a mistake - a crew member was accidentally seen reflected in a mirror - but director David Lynch liked the crew member's face enough to develop a character out of this technical error.
