Continuity mistake: When Lister picks up the camera at the start of the episode, he stands up and turns around. In the next shot, from the view point of the camera in his hand, the shot is still rotating as if he had just picked the camera up. (00:00:15)
Continuity mistake: Lister screws in Kryten's replacement head (the one without the 'guilt chip') in exactly the SAME direction that he unscrewed the original head (to be exact - clockwise) (00:09:50)
Continuity mistake: When Lister unscrews Kryten's head, the plastic bag on the table moves between shots. (00:11:30)
Continuity mistake: Just after Kryten says 'you bet your ass' he is holding onto his groinal attachment over his shoulder. In the next shot, his arm is lowered. (00:12:00)
Continuity mistake: When Kryten says 'you bet your ass' his cigarette has switched hands between shots. (00:12:00)
Continuity mistake: When Lister drags Kryten through a doorway by his groinal attachment, he is using one hand. In the next shot he is using both hands. (00:12:05)
Continuity mistake: When Lister pulls Kryten through a doorway by his groinal attachment, Kryten's cigarette is in his left hand. When the shot changes, the cigarette is now in Kryten's right hand. (00:12:05)
Continuity mistake: When the gunman ties the cable to himself, he walks past a window, then in the next shot he is stood in the centre of the same window. (00:15:40)
Continuity mistake: The cable attached to the gunman is pulled away from the wall when he shuffles past the window, yet when Lister opens the window, it is still attached. (00:15:55)
Continuity mistake: At the start of the episode when the Nazi commander is speaking to Ace, in all wide shots his left arm is wrapped around the crocodile, but in all close up shots his arm is by his side. (00:00:45)
Continuity mistake: When the Nazi commander throws the crocodile at Ace, it changes size between shots. As he throws it, it is small and easy to throw, yet in the next shot it reveals it is taller than Ace. (00:01:00)
Continuity mistake: When the Nazi commander throws the crocodile at Ace, the yellow curtain is behind ace as he falls. In the next shot, the yellow curtain is in front of him. It is clear he did not fall through the curtain as it does not move as he hits the floor. (00:01:00)
Continuity mistake: When Ace Rimmer releases the crocodile, it bites Captain Voorhese's head, and the two begin to fall when Ace removes Voorhese's parachute. When the crocodile lands on the ground a few minutes later, there is no sign of Voorhese. (00:02:15 - 00:04:25)
Continuity mistake: When Ace is firing at the Nazi guards from his parachute, a white sleeve is visible. In all other shots his sleeves are brown. (00:03:00)
Continuity mistake: When Ace drives the bike out of the shed, the piece of wood is between the front wheel and the handlebars. In the next shot, the piece of wood is resting on his arms. (00:03:25)
Continuity mistake: When Lister claims his 'prize' the king's hands are on his lap. In the next shot his right hand is clutching the helmet. (00:09:05)
Continuity mistake: When the tent disappears, Lister's locks are over his right shoulder. In the next shot they are over both shoulders. (00:10:00)
Continuity mistake: When the crew are in the cockpit when Ace Rimmer is entering their dimension, Rimmer hopes that it is not him. When he says this, there is smoke around him, but this smoke was not there in the previous shot. (00:10:45)
Continuity mistake: At the start of the scene where the crew are giving Rimmer a funeral, Lister is shown clutching his "tie", and turns to Kryten, but in the next shot, he is suddenly looking up at the ceiling. (00:24:25)
Continuity mistake: During Ace Rimmer's funeral, the blow up doll is not visible earlier in the scene next to the Cat, but then appears from nowhere. (00:24:50 - 00:25:40)
Chosen answer: In-universe, after leaving Red Dwarf after his first appearance, Kryten managed to crash Lister's space-bike into an asteroid. Lister found his remains and decided to rebuild him, however, due to the high level of damage and Lister's questionable repair skills, he was unable to recreate Kryten exactly, leading to changes in appearance, personality and accent. In reality, the original actor wasn't available, coupled with presumably practical concerns about one-off makeup as opposed to makeup for a regular cast member, so some visual changes were made.
