Audio problem: When Kryten starts looking over Lister's bunk trying to find the Polymorph, posing as the boxers, the boxers, and therefore the Polymorph, are visible on the bunk. The sound of the Polymorph transforming is heard, indicating the Polymorph has changed form, but the boxers remain there, without any transformation. It is not until a few shots after that the Polymorph has appeared to have changed form. (00:10:00)
Revealing mistake: When the Polymorph, posing at the snake, jumps on Lister, it is apparent that the snake on Lister has been replaced by a plastic inflatable replica that has no features and does not move. (00:10:05)
Character mistake: When Rimmer, Cat and Kryten go down to the cargo hold to search for the Polymorph, Kryten says "It's here" and "somewhere", but he delivers the line in an English accent and not in his robot voice. (00:13:15)
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. (00:18:00)
Suggested correction: It's impossible using today's technology, but maybe not in the future. Maybe they have metallic-like materials that flex back to a previous form after deformation.
Continuity mistake: When the group are about to open the door with the heat seeking missiles inside and the Polymorph sneaks up behind them, Lister is standing at the front of the group, Cat and Kryten are behind Lister and Rimmer is standing at the back, behind all three. In the next shot, as the missiles exit the door, Rimmer is now suddenly standing front of Cat. (00:24:40)
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. (00:24:45)
Other mistake: The milkshake and toffee crisp come out of a different vending machine to where they were ordered. (00:01:50 - 00:06:55)
Suggested correction: But they are dispensed at the most convenient location for the person who ordered it. Great customer service, which can't be classed as a mistake.
Other mistake: When Lister inadvertently sets off the Auto Destruct sequence, the computer voice says the ship will detonate in 15 minutes. The computer then says "the ship will detonate" every five seconds followed by how much time until detonation, but the time in which the computer says this is inconsistent. Two seconds after the computer says 15 minutes, the computer says the ship will detonate in 14 minutes 55 seconds. Ten seconds after saying that, the computer says the ship will detonate in 14 minutes 50 seconds. (00:01:50)
Suggested correction: He keeps hitting it to cancel the self destruct, which then speeds up the countdown.
Other mistake: When the group are discussing if they can override the Auto Destruct, the computer voice says 8 minutes 20 seconds until detonation. About 20 seconds after saying this, the computer voice then says 8 minutes 10 seconds until detonation. (00:02:35)
Suggested correction: This isn't a mistake; the system is malfunctioning. Getting the time wrong is very appropriate.
Other mistake: When Lister (in Rimmer's body) pleads the Cat to lend him his body, he says "how else can I pilot White Midget?" In the next scene, the Blue Midget is being piloted, and White Midget was originally abandoned for Starbug. (This mistake was admitted by the crew). (00:21:45)
Revealing mistake: When Rimmer is piloting Starbug in Lister's body, there is a shot of Starbug spinning in circles. This is a shot that was taken from S3 E2 Marooned, of Starbug crashing after colliding with the asteroid. The only difference is the planet in the background has been changed. (00:22:10)
Continuity mistake: From the model shot of Blue Midget, Kryten is seen sitting on the right. When the camera cuts inside the ship, he is sitting on the left. (00:22:40)
Suggested correction: When the exterior shot of Blue Midget is shown, it is not very easy to tell the crew apart. They appear blurred, so it is impossible to determine who is sitting in which place.
