Plot hole: Lister is not allowed any dangerous objects that he might try to commit suicide with, yet when he is with the canaries on their missions, he carries an assault rifle. The canaries aren't always supervised and it would be impossible for a guard to stop any of them putting a gun to their head and pulling the trigger. (00:05:05)
Suggested correction: We only hear from Rimmer that that's a rule. Rimmer is usually wrong about most things.
Plot hole: Lister and Kryten seem to know about Cassandra's prediction that Rimmer would sleep with Kochanski despite the fact that they were not there when Cassandra said it. (00:25:15)
Suggested correction: Rimmer told them, just not on screen.
Continuity mistake: In the scene on the Canaries' transport, where they first try to convince Kryten to record the women showering, Kochanski speaks the first line in the scene, but when the shot changes to the wide shot, she isn't there anymore. (Confirmed on the DVD commentary). (00:05:55 - 00:07:20)
Continuity mistake: When Kryten says about the cryptic clue, his arms are by his sides. In the next shot, they are outstretched. (00:14:15)
Visible crew/equipment: When the Cat says "You mean to help you get out if the program freezes" on Blue Midget, a soundman can be seen crouching behind the control panel. The top of his head is visible in the top right of the screen. (00:14:10)
Suggested correction: That is not the head of a soundman crouching behind the control panel, or any crew member for that matter. What you are seeing is Kryten's hand moving around.
Revealing mistake: After the T-Rex eats the curry, it starts stamping about the cargo bay, yet there are no ripples in the very watery curry. (00:08:30)
Revealing mistake: The potatoes used in spud duty are obviously just cardboard cut outs used to give the impression that there are lots of potatoes. (00:19:25)
Revealing mistake: When Rimmer puts the engaged blindfold on and sits on the toilet, he doesn't take his trousers down. (00:03:50)
Continuity mistake: When Hollister picks up the lemon drink, his left hand is by his side. In the next shot it is on his chest. (00:01:50)
