Continuity mistake: In the hologram simulation suite, the amount of smoke changes from cut to cut throughout the scene. (00:06:30)
Continuity mistake: At the disco, when the Rimmers are seated at their table, the plant moves from in front of the lamp to behind it. (00:15:40)
Continuity mistake: In the disco when Lister complains about the female Lister's attempts to impress him, his hair is in front of his left shoulder, then behind it. (00:19:10)
Continuity mistake: When the Cat jumps up to grab the mirrorball, a comb appears in his hand from nowhere before disappearing again. (00:20:25)
Continuity mistake: When the Cat dances at the disco, he jumps up and grabs the mirror ball with both hands. In the next shot he is only holding it by one arm. (00:20:25)
Continuity mistake: When Lister and Rimmer talk to Holly at the disco, Lister's arm is on the table. When the camera angle changes, it is on his lap below the table. (00:21:15)
Continuity mistake: In the quarters of the female versions of the crew, the newspaper clippings and certificates on the wall still have the name 'Arnold' on them, and not the female equivalent, as it was supposed to be. (00:23:15)
Continuity mistake: Starbug 1 is abandoned on backwards Earth. But it still appears twice more in this series.
Continuity mistake: Rimmer wears a hat with an antenna on the right hand side when on Starbug, and after arriving on Earth, but when he and Kryten are walking through the streets later on, the antenna is now on the left side of his hat, and is far more extended. (00:02:20 - 00:08:00)
Continuity mistake: When Kryten is piloting Starbug and gently "eases forwards", there is a shot shown from behind Starbug where it is driving out of the cargo bay to the exit, and it is shown a couple feet off the ground. When Starbug exits Red Dwarf in the next shot, Starbug is suddenly much higher above the ground. (00:04:20)
Continuity mistake: In the forest, Lister and the Cat take a poster off a tree. They then show it to the man who gives them a lift. The poster is different to the one in the forest. (00:16:05)
Suggested correction: If you look at 00:13:47, you'll see that the closest tree has an odd poster. The other trees have the poster that they showed to the man that gives them a lift.
Continuity mistake: After Starbug and Blue Midget leave Red Dwarf, there is a shot of Blue Midget driving away from the ship, towards the camera. Cat and Kryten are the only two on board as Rimmer and Lister are on Starbug, but there are three people shown inside Blue Midget. This is because the shot was taken from series two, in which Rimmer, Lister and Cat were inside it. (00:03:25)
Continuity mistake: When Lister is telling Rimmer that he is going to die and that Rimmer doesn't need food, there is snow over his face, hair and coat collar, but a few seconds later, the snow has mostly disappeared. (00:09:35)
Continuity mistake: At the start of the episode, it is clear that the capsule fully rotates and the "contents: 2" sign is not on the capsule. (00:01:05)
Continuity mistake: At the start of the episode when we first see the polymorph, it looks into the mirror, then covers its eyes. Yet when we see the reflection, it already has its hands over its eyes before it gets to the mirror. (00:01:30)
