Continuity mistake: When Bird-man loses his glasses, he is feeling his face. In the next shot both of his hands are on the floor. (00:25:40)
Continuity mistake: When the virus starts to eat the potatoes, Rimmer picks them up from the pile just below eye level. In the wide shot it shows the potatoes are just below waist level and Rimmer would have had to lean much further away from where he was standing to get the potatoes from that height. (00:20:00)
Revealing mistake: When Baxter puts the Cat's head in the drinks machine and says hot bovrill, Kryten can be seen mouthing the line behind him. (00:22:20)
Suggested correction: Kryten is not mouthing the line "Hot bovril." He is just moving his mouth slightly up and down, which coincidentally happened to occur when Baxter was saying the line.
Continuity mistake: When Bird-man's boots drop to the floor, the crew are looking straight forwards. In the next shot they are all looking up. (00:26:45)
Continuity mistake: When Pete eats Bird-man, Bob is with the crew in the cargo bay. When they run away, Bob disappears. (00:27:00)
Continuity mistake: When the crew are backing away from Pete, the way they are standing changes between long shots and close ups. (00:26:10)
Revealing mistake: In the scene where Kochanski, the Cat, and Kryten first discover the time wand, there are a group of Canaries who are frozen in time from its effects. In the first shot of these people, the woman on the far right of the screen blinks her eyes. (Confirmed on DVD commentary). (00:15:50)
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)
Visible crew/equipment: When Lister is putting the chicken vindaloo on the table, a stage light is visible on the left hand side of the screen. (00:11:50)
Visible crew/equipment: In the Captain's Office, when Rimmer says "That is not true. We played the joke on Mr. Ackerman, sir", a stage light is reflected on the object behind him and Lister. (00:01:05)
