Revealing mistake: In the sleeping quarters, Rimmer turns on a swivel chair. This would be impossible as he is a hologram. 3.10. (00:03:10)
Suggested correction: As a hologram, this would also mean Rimmer could not touch or sit on the chair. The chair was likely a hologram as well, used to be operable by Rimmer. It has been shown before that Rimmer can still interact with other holographic objects.
Revealing mistake: With the Matter Paddle, Kryten transports into the sleeping quarters, and then transports onto the bunk. When Kryten transports onto the bunk, the Cat's position on his chair visibly alters on screen, showing where the scene was edited to make Kryten appear as if he transporting. (00:03:15)
Revealing mistake: When Kryten transports the Matter Paddle back to Red Dwarf, the position of Kryten's hand visibly alters on screen, revealing where the scene was edited to make the paddle appear as if it had transported. (00:06:30)
Revealing mistake: When Lister is in jail with the Cat, as he is looking out of the window, he is naming famous people. He says "Mussolini" before he actually looks at him. (00:10:55)
Suggested correction: First, Lister is shown looking out the window throughout the scene, and second, he still has an entire view of outside the window within his eyesight. Lister likely already seen Mussolini within his eyesight before turning to face his direction, which he likely did to assure himself it was definitely Mussolini.
Revealing mistake: When Ghandi explodes, there is a single shot where he had disappeared before the explosion goes off. (00:22:35)
Revealing mistake: When the Dalai Lama explodes, there is a single shot where he has disappeared and a yellow cloth has taken his place just before the explosion. The cloth then lands in the background. (00:22:55)
