Plot hole: Allman does not remember his trial when The Inquisitor erases him, yet Lister and Kryten do remember their trial when they are sentenced. (00:01:20 - 00:13:30)
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: At the start of the episode, when Lister and Kryten talk about Lister's comic, a boom mic shadow can be seen on Kryten's head. (00:02:10)
Revealing mistake: Just after the Trojans' conversation, there are two jolts. Lister jumps back too soon on the second jolt. (00:03:30)
Continuity mistake: When Starbug jolts for the first time, Rimmer is looking to his right. The camera cuts and he is looking forwards. (00:03:30)
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)
Visible crew/equipment: When Lister is being taken over by The Inquisitor, a boom mic shadow can be seen moving on Kryten's chest. (00:04:15)
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)
Continuity mistake: After the future Kryten cuts off The Inquisitor's hand with the chainsaw, he kicks the glove which lands about 7 feet away from Lister. In the next shot Lister simply bends down and picks the glove up from in front of him. (00:13:45)
Continuity mistake: When The Inquisitor jumps Kryten from behind, Kryten's arm changes positions between cuts. (00:14:05)
Continuity mistake: When The Inquisitor jumps Kryten from behind, he used both hands. In the next shot he is only using one hand to hold him. (00:14:05)
Continuity mistake: Lister says his ID code is Lister-D-00169, yet in Furture Echoes he gave it as RD-52169. (00:14:55)
Continuity mistake: When Lister says 'We don't exist here anymore,' the way Kryten is facing changes between cuts. (00:15:10)
Continuity mistake: When the Cat says, "So what do we do with them?" Kryten disappears from Lister's left between camera shots. (00:17:30)
Continuity mistake: When The Inquisitor attacks the crew in the lift, Kryten and the Cat go from crouching to standing stright up between camera angle switches. (00:18:25)
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)
Audio problem: When Kryten says 'Excuse me, could I just distract you for a brief second?' his lips are out of sync with the dialogue and continue to move after he has finished speaking. (00:23:35)
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.
