Revealing mistake: In the sleeping quarters, Rimmer turns on a swivel chair. This would be impossible as he is a hologram. 3.10. (00:03:10)
Suggested correction: As a hologram, this would also mean Rimmer could not touch or sit on the chair. The chair was likely a hologram as well, used to be operable by Rimmer. It has been shown before that Rimmer can still interact with other holographic objects.
Emohawk - Polymorph II - S6-E4
Continuity mistake: At The End of the episode when Lister hands Duane the cannister, the shot changes and Lister is facing the opposite direction. (00:27:05)
Revealing mistake: When the two Rimmers are exercising, there are no stars visible out of their window. (00:11:20)
Other mistake: The tax letter and Rimmer's mother's letter are both already opened before Lister takes the letters out. As there is no one else aboard Red Dwarf, the letters would not have been checked by anyone so they should still be sealed. Also, not all of the letters are already open, just the two that Rimmer receives.
Suggested correction: Unfortunately, we aren't provided with enough information about the envelopes Dave didn't open to determine if they were all unsealed or not. Maybe all JMC post is opened and checked before being put in the post pod. That way, any potential threat is identified before the pod gets on board the ship, which seems a sensible security measure.
Continuity mistake: When Kryten says 'you bet your ass' his cigarette has switched hands between shots. (00:12:00)
Continuity mistake: At The End of the episode, when the future Lister and the babies appear, Rimmer has his arms folded. In the next shot, Rimmer's hands are on his hips. Also, Lister's locks change positions. (00:27:50)
White Hole - S4-E4
Continuity mistake: When Kryten tells the toaster not to offer Lister any grilled bread products, Lister is looking down at the table behind him. In the next shot he is looking over his shoulder at the camera. (00:02:50)
Continuity mistake: After Rimmer walks out of Lister's exam at The End of the episode, you can see he walks into the sleeping quarters, yet in the next shot he is walking down a corridor. (00:28:30)
Revealing mistake: When Lister is in jail with the Cat, as he is looking out of the window, he is naming famous people. He says "Mussolini" before he actually looks at him. (00:10:55)
Suggested correction: First, Lister is shown looking out the window throughout the scene, and second, he still has an entire view of outside the window within his eyesight. Lister likely already seen Mussolini within his eyesight before turning to face his direction, which he likely did to assure himself it was definitely Mussolini.
Continuity mistake: When remote controlled Lister is strangling the Cat, his locks are partially over his left shoulder and partially behind his back. When Lister picks up the bazookoid, his locks are all over his left shoulder. (00:23:10)
Continuity mistake: After the Cat starts to cry, he is looking at Kryten and Lister. In the next shot he is looking down. (00:04:50)
Continuity mistake: When the Cat asks if fish swim south for the winter, Kryten is looking at him. In the next shot, as Kryten answers, Kryten is looking up and away from the Cat. (00:02:05)
