Revealing mistake: When Kryten is doing his driving test, as soon as we see Rimmer and Kryten in the cockpit you can see the wire attached to Chris Barrie behind him, next to the aerial on his hat, going vertically out the top of the frame. (00:03:40)
Revealing mistake: After Starbug has left Red Dwarf, the scene cuts to inside the ship where Rimmer tells Kryten to autopilot, and the background of space is entirely still, even though the ship is moving. (00:04:45)
Suggested correction: Stars are so far away that they do not appear to move when travelling in space, unless you reach incredibly high speeds or change direction.
Revealing mistake: After landing on Earth, Rimmer and Kryten are standing on land. When Kryten asks "What is this place?", a car can be seen driving forwards in the far background, even though everything in this version of Earth is supposed to work backwards. (00:06:15)
Revealing mistake: When Lister and Cat are in Starbug searching for Rimmer and Kryten, the background of space shown out the window remains entirely still and doesn't move. (00:11:15)
Revealing mistake: Lister and Cat get a ride to Nodnol after a man they bump into offers to take them in his van. The logo on the van appears completely normal, and has not been reversed, even though everything in this version of Earth is supposed to be reversed. (00:16:15)
Revealing mistake: The scene where the pub manager comes backstage to yell at Rimmer and Kryten was filmed, and then reversed to appear as if he was yelling backwards. Rimmer blinks when he is being yelled at, and due to the scene being played in reverse, his facial movements appear reversed, even though he is supposed to be moving forwards. (00:22:00)
Revealing mistake: Near The End of the episode, Kryten and his employer are seen arguing in supposedly backwards English. However, when you watch the episode how the people of earth would see it on the second DVD, Kryten and his employer aren't speaking English, they are just speaking plain gobbeldy-gook, even although when you see the people of Earth talking on the DVD they speak correctly. (00:22:30)
Revealing mistake: During the fight, there is a man in a 'Flash Gordon' t-shirt with the logo forwards. (00:24:45)
Revealing mistake: When Rimmer stands up from underneath the table, just before he says, "Thanks for your support" to Lister, listen very carefully and you can hear the stunt director saying "Action!" backwards. This shot was the splice point between the reversed and the regular footage. (I know this mistake is listed as being in the 'backwards version' on the DVD, but it is in the regular broadcast version too - you just have to listen harder for it.)
Revealing mistake: At the start in the cockpit of Starbug, the green screen behind Lister is visible instead of the painted starfield that should be there. (00:02:35)
Suggested correction: That is because Starbug is parked inside Red Dwarf at the time, and the stars wouldn't be visible.
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)
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)
