- With the shown partly being inspired by Blade Runner, the ninth series, a mini-series titled "Back to Earth", was meant to be the last series on the show and as such parodies Blade Runner by having the crew seek the shows writer to ask for more episodes.
- In the episode DNA (series 4 episode 2), when kryten becomes human, the picture shown to Lister, the 'double polaroid' was actually a picture of one of the shows crew rather than just a prop so as to get a real reaction from Craig Charles.
- In the shows cannon Lister is his own father and technically his old love interest Kochanski is his mother.
- While not explicitly explained in the show it's thought that in the shows connon the reason Holly disappears after series VIII is a tap being left on in one of the storage decks which ends up flooding Holly's circuits.
- An American version of the show had a pilot episode made but was so bad not even the pilot made it to air. The episode can be found online though the poor timing of jokes and questionable choices of actors for certain roles makes it painful to watch. Needless to say no more episodes were made for the american verion
