Revealing mistake: During the 'Two Listers' scene, specifically the cut when Kryten tosses the apples to the Listers, the split screen is quite visibly moving in between the chairs. (00:22:55)
Continuity mistake: When Lister swings the axe at The Cat and hits the door frame, the axe head bends. When Lister pulls the axe out, its head is fine again. (00:22:30)
Visible crew/equipment: During the scene when Starbug crashes, the camera then does a barrel roll and you can see wooden roof beams of the set and the stage lighting. (00:09:55)
Continuity mistake: When the second version of Allman appears, he has his arms folded. In the next shot, they're down by his side. (00:01:25)
Timeslides - S3-E5
Continuity mistake: We are told that it is impossible to move outside the frame of a slide, yet when we are shown the slide of young Lister and his band, all we see is the band on stage but the crew move freely about the pub. (00:11:40)
Revealing mistake: At the start in the cockpit of Starbug, the green screen behind Lister is visible instead of the painted starfield that should be there. (00:02:35)
Suggested correction: That is because Starbug is parked inside Red Dwarf at the time, and the stars wouldn't be visible.
Visible crew/equipment: When Todhunter asks everyone to stand for the cutting of the cake, a red boom mic can be seen in the top left corner of the screen. (00:12:05)
Visible crew/equipment: After Lister is attacked by low Kryten, he sneaks through the cargo bay. There is a shot where the camera is following Lister as he sneaks around a corner, if you look at the floor you can see the shadow of the cameraman. (00:14:45)
Terrorform - S5-E3
Continuity mistake: When Lister, the Cat and Kryten figure out how to escape, Kryten says 'precisely' and raises his right hand. In the next shot, both of his hands are raised. (00:22:15)
Continuity mistake: Able's head bounces off the simulant and lands behind him, yet when Lister sends the gelf and simulant back to their ship, the head is next to him on the floor. (00:20:10)
Terrorform - S5-E3
Continuity mistake: At the start of the episode Kryten has crashed Starbug 1 onto the psi-moon. Lister and the Cat rescue him in Starbug 2, yet when the crew search for Rimmer in the swamp, they are in Starbug 1. (00:06:10 - 00:19:45)
Timeslides - S3-E5
Continuity mistake: When the slideshow starts, the photos in Lister's hands disappear between camera cuts. (00:06:20)
Revealing mistake: Starbug and Blue Midget wobble on a number of occasions during the chase. (00:23:25)
Confidence and Paranoia - S1-E5
Continuity mistake: At the start of the episode, when Lister is watching the film, keep an eye on his milkshake. One moment the glass is on the table, then when the camera cuts, he's drinking from it. (00:02:25)
Timeslides - S3-E5
Deliberate mistake: The Eagle on Hitler's briefcase is that of the (post war) Federal Republic of (West) Germany - not that of the Nazi German Third Reich. This was deliberate - showing the Third Reich Nazi emblem of an eagle holding a swastika would have had the episode banned in Germany, Austria, Poland and any number of other European countries. (00:08:25)
Visible crew/equipment: When Binks arrives on Starbug, a boom mic can be seen at the top of the screen. (00:07:45)
