Audio problem: When the high Lister plays the harp, his fingers are out of sync to what is being played. (00:11:30)
Quarantine - S5-E4
Visible crew/equipment: When Lister wipes down the biohazard cabinet, a boom mic can be seen in the top right of the screen. Also, just before the camera moves past the pillar, the entire microphone and arm can be glimpsed. (00:05:00)
Continuity mistake: Just after The Inquisitor is frozen when Lister and Kryten switch gauntlets, the glove gets onto Kryten's hand in one camera cut. (00:24:30)
Suggested correction: He's holding the gauntlet in his hand, but the angle of the camera makes it appear that he's wearing it.
Continuity mistake: When The Inquisitor jumps Kryten from behind, Kryten's arm changes positions between cuts. (00:14:05)
The Last Day - S3-E6
Revealing mistake: You can tell Robert Llewellyn is reading his lines when Kryten receives the computer chip. He is looking much lower than the chip in his hand and it was obviously quite a complicated piece of dialogue to remember. (00:12:35)
Stasis Leak - S2-E4
Continuity mistake: When Rimmer is talking to the captain while he is dressed as a chicken, the blue bucket moves between camera cuts from being hung up on the large canister, to being on the floor next to Rimmer's bed. (00:20:35)
Continuity mistake: When we see Rimmer's Death video, the atomic blast pushes him into the Captain's office. However, in "The End," Holly indicates that the two piles of dust next to each other in the centre of the drive room are Captain Hollister and Rimmer. (00:10:00)
Quarantine - S5-E4
Revealing mistake: As pointed out by Danny John Jules on the DVD Commentary, during the 'Feckles, Heckles, Hackles, Schmeckles' argument, Cat pushes his face right against Kryten's, leaving a brown makeup smear on Kryten's forehead. The mark is gone in the next shot. (00:19:45)
Continuity mistake: When Rimmer walks down the corridor, his hair is a mess. When he enters the medi-bay it is tidy. (00:25:25)
Revealing mistake: The spike that kills Pete Tranter's sister is visible before she reacts to it, just below her elbow. (00:21:20)
Other mistake: Kryten places Rimmer's light bee on the floor, then begins the process of reinitialising him. As the process finishes and Rimmer looks at Lister (who looks away), the light bee, which should be hovering within his torso projecting his image, is still visible on the floor between his feet. (00:06:00)
Revealing mistake: In the drive room when Lister kicks the vending machine after he finds out he's going to die, you can see the shadow of the machine wobbling as if it were lightweight. (00:20:20)
Continuity mistake: When Lister claims his 'prize' the king's hands are on his lap. In the next shot his right hand is clutching the helmet. (00:09:05)
Continuity mistake: When the Cat is kissing the photo of the mermaid, in the next shot the photo has disappeared. (00:24:50)
Continuity mistake: When Kryten is restored to his factory settings, the woman is pressing buttons on the keypad. In the next shot, her arm is by her side. (00:17:40)
