Red Dwarf (1988)

Back To Reality - S5-E6

Factual error: While it is true that lithium carbonate can be used to treat depression and other psychiatric disorders, it cannot be administered in gaseous form. It is a very stable salt and only starts to form vapour at 1,310 degress Celcius. Spraying it about as a 'mood stabliser' at that temperature, as Kryten does, is going to kill everyone on the spot.

Nanarchy - S7-E8

Lister: What, they fixed your core program and then decided they'd be better off without you?
Holly: Yeah, it was shortly after they met me.

Trivia: It was rumored that Alfred Molina and Alan Rickman wanted the part of Rimmer. Lee Cornes also auditioned for this role (he later guest starred on the show), as did Hugh Laurie. Robert Bathurst, Norman Lovett and David Baddiel auditioned for the role of Lister.

Meltdown - S4-E6

Question: When Kryten and Rimmer were doing the roster of their ranks, Why did Kryten skip the old woman in the black dress with the white shoulder sash between Dali Lama and Mr. Noel Coward?
