Continuity mistake: Season 2, episode 5 "Smoke and Mirrors": Roy's lipstick alternates between bright pink and more of a peachier colour throughout the scenes.
The Haunting Of Bill Crouse - S1-E5
Continuity mistake: Bill Crouse is sitting at a desk talking to his colleague about Jen. The first two shots show him sitting back on the chair with his legs up on the desk. The next shot, he has instantly moved to sitting normally with his legs down and leaning forward. (00:14:20)
Suggested correction: After he says he was the last person to sleep with Jen, the camera is off him for at least 4 seconds, enough time for him to sit up.
Continuity mistake: When Jerome pulls one of the disabled men out of his wheelchair, both of the disabled men on screen are in different wheelchairs to those they used in the scene where we first see them (when Roy files the police report).
Continuity mistake: Season 3 Episode 1 'From Hell' When Roy says "Nice glasses" and Moss replies with "Not as nice as your momma's glasses", The Red Door between Roy changes from being closed to being open.
