11. During the filming of a scene in the pilot taking place in Laura's room, Frank Silva, a set dresser, accidentally trapped himself in the room by inadvertently moving a dresser in front of the door.

14. Killer BOB After filming him crouched at the foot of Laura's bed, looking through the bars of the footboard, as if he were "trapped" behind them, Lynch filmed the scene a second time, without Silva.

15. Killer BOB After reviewing the footage, Lynch liked Silva's presence so much that he decided to make him part of the series.

16. Killer BOB Later that day, a scene was being filmed in which Palmer's mother experiences a vision which terrifies her; at the time, the script did not indicate what Mrs Palmer had seen to frighten her.

17. Killer BOB Lynch was pleased with how the scene turned out, but a crew member informed him that it would have to be re-shot, because a mirror in the scene had inadvertently picked up someone's reflection.

18. Killer BOB When Lynch asked who it was, the crew member replied that it had been Silva.

19. Killer BOB Lynch considered this a "happy accident," and decided at that point that the unnamed character to be played by Silva would be revealed as Palmer's true killer.

25. Laura's body Lynch was reportedly pleased with the lifelike, unscripted moment in dialogue, and kept the mistake in the final cut.
