Revealing mistake: After the Cat's dance, Lister says 'we are outta here' and pulls the level, at which point the crew all fall back as if Blue Midget had rushed forwards. However, in the model shot of the ship it shows it scraping its foot on the floor before it runs forwards, meaning the crew should not have fallen back in their seats.
Revealing mistake: In the scene where Kochanski, the Cat, and Kryten first discover the time wand, there are a group of Canaries who are frozen in time from its effects. In the first shot of these people, the woman on the far right of the screen blinks her eyes. (Confirmed on DVD commentary).
