Red Dwarf (1988) - 10 mistakes in "Polymorph"

Plot hole: Right after the shrinking boxers scene, Kryten says the small boxers are missing from the bunk, but you can see them right in front of him.

Continuity: At the start of the episode, it is clear that the capsule fully rotates and the "contents: 2" sign is not on the capsule.

Continuity: 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.

Continuity: Kryten removes the polymorph underpants and throws them under the covers of Lister's bed. When he checks the bed and pulls out a snake the pants are now on top of the covers (even though he says they're gone) and the covers themselves are now arranged differently.

Continuity: At the end of the episode, the second Polymorph changes from Lister back to its original form. As this happens, the background changes completely.

Factual error: The polymorph goes through a metal pipe and a tap which bulges and becomes mis-shapen. The tap then changes back to its original shape, which is impossible.

Visible crew/equipment: When the bazookoid blasts hit the Polymorph near the end, you can see the stand that's holding the Polymorph at the bottom of the screen.

Audio problem: When Lister says "he was in sickbay for a week", once the shot changes we once again hear him say "for a week". Evidently, the line was intended to carry on into the next shot but wasn't edited out.

Revealing: The cardboard box that the Cat holds up to block the heat seeking missiles has two pre-cut holes in it. You can just barely see them as he takes the box from the shelf.

Continuity: When Lister is preparing the meal, he puts all the ingredients into the microwave and closes the door. When he opens it again, a plate has magically appeared inside the microwave.
