Revealing mistake: The first time you see Lister, the Cat, Kochanski and Kryten in the AR machine you can see the cat opening his eyes realising that it is not in the script, smiling and then closing his eyes. (00:04:50)
Continuity mistake: When the crew are plasticine in the screensaver, the Cat slides into the igloo. From one shot he is sliding towards the igloo from an angle, but in the next shot he is heading straight for the igloo. (00:14:55)
Continuity mistake: When The Cat does his dance with Blue Midget, he stands behind one of the legs of Blue Midget and changes his clothes. The old clothes he throws on the ground when changing disappear in the wide shot of the landing area. (00:08:55)
Continuity mistake: During the Cat's dance, he taps his feet and tilts his head back, which Blue Midget copies. In the next shot Blue Midget is looking downwards and then proceeds to do the same dance it just did in the previous shot. (00:10:00)
Revealing mistake: After the Cat's dance, Lister says 'we are outta here' and pulls the level, at which point the crew all fall back as if Blue Midget had rushed forwards. However, in the model shot of the ship it shows it scraping its foot on the floor before it runs forwards, meaning the crew should not have fallen back in their seats. (00:10:50)
Continuity mistake: During the Cat's dance scene with Blue Midget, we see one shot of Blue Midget doing the air guitar move, but in the next shot, his arms are not visible at all. It changes between these two differing shots throughout the closing end of the dance routine. (00:10:10)
Revealing mistake: Just before the Cat starts his dance, Kochanski is at the back of the cockpit of Blue Midget and is bouncing up and down, yet the ship is not moving. When it starts moving, Kochanski is sitting still. (00:08:05)
Visible crew/equipment: In the cell at the start of the episode, after Rimmer says they have to escape, a boom mic is visible at the top of the screen. (00:03:10)
Continuity mistake: When the Cat does his tap dance, he starts 20 feet away from Blue Midget and does not move from his position during the dance. When he finishes, he taps Blue Midget's leg. (00:09:30)
Revealing mistake: When Rimmer is typing on the keyboard, what he is saying does not match what he is typing. He is typing randomly. (00:12:20)
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.
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)
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: After the Cat has performed his dance routine, he begins to smoke a cigar and puts it down. The shot cuts to the ground controller, but when the shot cuts back to the Cat, the cigar is back in his mouth and has already been smoked. (00:10:30)
