Continuity mistake: When Lister is explaining the ending of the movie, he says "It's about a dude who sacrifices his life for love" whilst Rimmer looks at him, but in the next shot, Rimmer is suddenly looking forwards before turning back to Lister saying "as if." (00:02:55)
Continuity mistake: When Kryten tells Rimmer he doesn't have the brain that can accept an implant, he says "No" and begins walking around the table.

Audio problem: When Rimmer is talking to Lister, Cat and Kryten in the dress, the Cat says "We thought you'd gone nuts" and the shot cuts to Rimmer where the Cat then says "We were trying to heal you."
