Red Dwarf/Trivia

• Hey, It's That Guy!:
  • Cassandra, from the episode of the same name, is played by Geraldine McEwan (of Henry V and Robin Hood: Prince of Thieves fame).
  • Craig Charles lampshaded this when they were filming the reunion scene with Selby and Chen. He replied to Kryten's question, 'You know these people, sir?', exclaiming, 'Of course I do - they're in Eastenders!'
    • As is Kill Crazy, incidentally.
    • And now, so is Baxter.
  • The US pilots had a ton of these — Tom from Scary Movie 4 played Lister, Daphne Moon popped up as Holly, Jadzia Dax appeared as the second cat (the first was played by Hinton Battle, who isn't a particularly well-known actor but is pretty legendary in the world of dancing), and Kryten was played by... er, Robert Llewelyn, who was Kryten in the BBC series Red Dwarf.
    • Apparently, Hinton Battle is a hero of Danny John-Jules. Battle apparently put a lot of work into his version of The Cat, making John-Jules something of an Ascended Fanboy.
  • And Mr. Weasley is Peterson, Peter Pettigrew is a game custodian in Back to Reality, and Bubble gets to work on a Holoship.
  • Susan is the queen in the medieval virtual reality game.
  • Lister's confidence is personified by Craig Ferguson. Yep, same one.
  • Professor Mamet, Kryten's creator is played by Jenny Agutter.
  • The abandoned ship's computer in DNA is voiced by Richard Ridings - AKA The Mentor, Sarge, and Daddy Pig.
  • The woman the Polymorph disguises itself as before sucking out the Cat's vanity would go on to play the eyepatch-wearing Madam Kovarian in Doctor Who.
  • "Nicey" Ackerman is Lewis.
  • In Parallel Universe Deb Lister (Lister's female equivalent) is Brigadier Bambera!
• The Pete Best: Kryten first appeared in a one-off appearance in Season 2 where he was played by David Ross. The character proved popular and opened up more storytelling possibilities, so Grant and Naylor decided to bring him back as a regular — Ross was unable to take the role due to scheduling commitments, however, so he was replaced by Robert Llewellyn (with a Hand Wave about how his appearance and personality was now different). Llewellyn proceeded to make the part his own.
• Trope Namer:
  • Everybody's Dead, Dave: Repeated to Overly Long Gag levels in the first episode.
  • Hard Light: Rimmer.
  • More Teeth Than the Osmond Family: The polymorph.
• What Could Have Been: A deleted scene from Series II has the Cat and the Toaster singing a duet. Sadly, the Toaster's lines were never recorded.
  • The first series would have ended with the episode "Confidence and Paranoia", and would've had a cliffhanger ending with Kochanski being resurrected as a second hologram. But as the planned second episode "Bodysnatcher" just wasn't working, they scrapped it, rewrote the ending for "Confidence and Paranoia" to have a duplicate of Rimmer activated instead, and wrote the episode "Me^2" as a new series finale.
  • Similarly, the planned opener for the third series would've been an episode titled "Dad", which would've resolved the cliffhanger of Lister's pregnancy and re-introduced Kryten on-screen, as well as having Lister give birth to a single baby boy. Again, the episode wasn't working so it was scrapped and replaced by a comically-rapid Opening Scroll (which also resolved the "Where do the twins come from?" dangling plot thread for good measure).
  • A third Red Dwarf novel co-written by Grant and Naylor, titled The Last Human, was being planned before their writing partnership split. (Naylor later re-used the title for his own novel, even though the stories were different.)
  • The eighth series finale "Only the Good..." had four different endings altogether. The original ending (which was filmed but not used) was a happy ending where they saved the ship and took it back for themselves. The second ending (written, but not filmed) was a Downer Ending with Rimmer trapped aboard the disintegrating ship. The third ending involved Ace Rimmer coming to the rescue at the last minute — this was ready to be filmed, to the extent that Chris Barrie was in his Ace costume, before the broadcast ending was thought up and hastily thrown together.
