Continuity mistake: When Rimmer stresses out while preparing for his exam, he puts his hands on his face, and screams whilst starting to bend over. In the next shot, Lister wakes up, and Rimmer is suddenly standing upright. (00:13:20)
Continuity mistake: When Holly interrupts Rimmer learning Esperanto saying "The menu looks interesting", he appears on the TV screen, with his chin blocked by the edge of the frame. The shot then cuts to a view of the screen, and his entire face is suddenly fully in the frame. (00:05:00)
Stasis Leak - S2-E4
Continuity mistake: In the lift, when the woman in the video is explaining how the lift works, she mentions "a bag will drop containing sedatives and cyanide capsules", pointing upwards. The shot cuts to Lister, and the woman in the video can be seen to the left of shot, with her arms at her side. (00:08:35)
Stasis Leak - S2-E4
Continuity mistake: In the hotel room, when future Lister is telling Lister he doesn't look pleased to see him, the two Listers are standing directly in front of each other, but from another angle, future Lister is standing around 90° rotated from before, and a few steps to the right of Lister. (00:25:35)
Stasis Leak - S2-E4
Continuity mistake: When Lister is in the hotel room with future Lister and Kochanski, Lister says he came because he thought he was going to get married whilst talking to future Lister, but in the next shot, Lister's facial expression has suddenly changed and is now looking more confused. (00:25:35)
Stasis Leak - S2-E4
Continuity mistake: When future Lister is making Lister and Cat leave the hotel room, Lister begins talking to future Lister about living his life. Future Lister is standing beside the door in one shot, but has his head suddenly resting on the door in the next shot. (00:26:25)
Other mistake: The shots of Blue Midget driving back to Red Dwarf that are shown from behind are visibly the exact same shots used each time. This is evident as the driving movements of Blue Midget, its position in the frame, and Red Dwarf's position in the background are all identical each time.
Visible crew/equipment: When Lister steps back inside the observation room after Rimmer leaves, a stage light can be seen reflected in the window-like light fixture on the wall. It can't be a light on the ship as none of the lighting on Red Dwarf is in the shape of the light seen in the reflection. (00:14:05)
Other mistake: Holograms are often seen passing through physical objects, walls, furniture, and other people. Yet, they have a physical object generating the hologram: their light-bee. This would not be able to pass through other solid objects.
Continuity mistake: When Rimmer is about to tell Lister how many times he made love, Lister tells him that he'll "wake up in the morning with a hangover." But Rimmer and Lister already have fallen asleep and woken up, and they have the hangovers right now.
Other mistake: When Kryten and Camille are having dinner, Camille puts her "hand" in the soup and begins slurping it up. The level of soup remains the same and doesn't lower despite being slurped. (00:22:25)
Character mistake: When Rimmer, Cat and Kryten go down to the cargo hold to search for the Polymorph, Kryten says "It's here" and "somewhere", but he delivers the line in an English accent and not in his robot voice. (00:13:15)
Other mistake: When the group are discussing if they can override the Auto Destruct, the computer voice says 8 minutes 20 seconds until detonation. About 20 seconds after saying this, the computer voice then says 8 minutes 10 seconds until detonation. (00:02:35)
Revealing mistake: When Lister and Cat are in Starbug searching for Rimmer and Kryten, the background of space shown out the window remains entirely still and doesn't move. (00:11:15)
Revealing mistake: The scene where the pub manager comes backstage to yell at Rimmer and Kryten was filmed, and then reversed to appear as if he was yelling backwards. Rimmer blinks when he is being yelled at, and due to the scene being played in reverse, his facial movements appear reversed, even though he is supposed to be moving forwards. (00:22:00)
Revealing mistake: Lister and Cat get a ride to Nodnol after a man they bump into offers to take them in his van. The logo on the van appears completely normal, and has not been reversed, even though everything in this version of Earth is supposed to be reversed. (00:16:15)
Plot hole: The barroom tidy scene in the pub makes absolutely no sense. It is established that this fight started because Lister and the Cat uneat a man's pie, which causes the man to punch Lister, and then the barroom brawl happens, but the events are reversed due to this version of Earth being set in a backwards reality. However, if the events of this fight are put into chronological order, this would mean that Lister uneating the man's pie and being punched by him would have been the last thing to happen during this fight, as it was the first thing to happen in reverse order, and therefore, would also means that there would have been no real reason for the pub patrons would get into a brawl in the first place, as nothing had occurred at that time. (00:23:15)
Revealing mistake: After Starbug has left Red Dwarf, the scene cuts to inside the ship where Rimmer tells Kryten to autopilot, and the background of space is entirely still, even though the ship is moving. (00:04:45)
Suggested correction: Stars are so far away that they do not appear to move when travelling in space, unless you reach incredibly high speeds or change direction.
Other mistake: When Rimmer is testing Kryten on a book of space traffic signs, Kryten stops on one page and is tested, which he says the sign is a binary star. Without turning the page, Rimmer points to a second sign on the same page asking what it is, which he points out is a blue giant about to supernova. After pointing to the time hole, Rimmer turns back to the book, saying "Right. What's this?" whilst still on the same page, pointing to a another sign. The page that is being used has one sign shown on the right hand side page, and the left hand side page is completely blank, equalling one sign on both sides of the page, but two or three signs are made mention to when on the page. (00:05:20)
Confidence and Paranoia - S1-E5
Revealing mistake: When Confidence is trying to get Lister to take his helmet off, Lister climbs over a railing and jumps around him. It is clear that the footage of Lister jumping around was slowed down to make his movement appear as if there is a lack of gravity. (00:26:35)
