Factual error: While it is true that lithium carbonate can be used to treat depression and other psychiatric disorders, it cannot be administered in gaseous form. It is a very stable salt and only starts to form vapour at 1,310 degress Celcius. Spraying it about as a 'mood stabliser' at that temperature, as Kryten does, is going to kill everyone on the spot.
Visible crew/equipment: When Rimmer is being questioned by The Inquisitor, a full boom mic and arm can be seen rising out of shot by the three candles on the right of the screen. (00:08:35)
Revealing mistake: Just after the Trojans' conversation, there are two jolts. Lister jumps back too soon on the second jolt. (00:03:30)
Quarantine - S5-E4
Continuity mistake: When Kryten injects the luck virus into Lister's neck, the gun disappears from Kryten's hand between shots. (00:23:25)
Visible crew/equipment: A boom mic shadow appears on Lister's head just after he opens the door with the severed hand. (00:19:20)
Continuity mistake: When Starbug gets taken over and Kryten says it is not a malfunction, he has his hands in the air. The camera cuts to Rimmer, and Kryten's hands are by his side. (00:03:45)
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)
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)
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)
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)
Visible crew/equipment: When Binks arrives on Starbug, a boom mic can be seen at the top of the screen. (00:07:45)
Terrorform - S5-E3
Continuity mistake: The cutting torch Kryten uses to cut his hand off appears from nowhere. (00:02:20)
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)
