Revealing mistake: During filming of the this episode, Craig Charles was called away for the birth of his son, Jack, so production manager Mike Agnew stepped in. Although Lister is wearing a space suit at the time you can still tell which part is Mike thanks to a continuity error - Mike forgot to put on Lister's plaster cast. (00:15:15)
Visible crew/equipment: In the flashback scene of Lister and his mates, just after Lister says about brains in jars, a yellow boom mic can be seen at the top of the screen. (00:06:00)
Continuity mistake: When the low Kryten takes the spinal implant from low Lister, he uses his right hand. In the next shot, the implant has switched hands as Kryten uses his right hand to lift up Lister's head. (00:16:40)
Continuity mistake: When Ace Rimmer is talking to the Cat as a priest, the Cat has the pipe in his mouth in one shot, then he is holding it in front of him in the next. (00:03:45)
Continuity mistake: Just before Lister says 'I'm going to give him Lisa Yates' he is looking forwards. When the camera angle changes he is looking at the Cat. (00:18:15)
Revealing mistake: After the T-Rex eats the curry, it starts stamping about the cargo bay, yet there are no ripples in the very watery curry. (00:08:30)
Continuity mistake: After the Cat says about mooning out of the windows when Starbug gets hit, Kochanski falls back on her chair with her arms outstretched. In the next shot she is holding onto the monitor again. (00:25:00)
Terrorform - S5-E3
Visible crew/equipment: When Lister and the Cat type into the computer, in the shots of their reflections, the lens of the camera can be seen reflected between them. (00:05:00)
Continuity mistake: During the battle, the Dalai Lama can be seen running through the field after he is killed. (00:23:05)
Out Of Time - S6-E6
Visible crew/equipment: In the scene just befoe Lister & the Cat go into stasis, a boom mic shadow can be seen moving on the desk in front of Rimmer. (00:12:20)
Quarantine - S5-E4
Audio problem: When Dr. Lanstrom says hello into the walkie talkie, her lips do not move. (00:08:40)
Continuity mistake: Rodon is revealed to be the Cat's older brother, and the rebelling cats refer to the Red Dwarf itself as the ship of their birth, but in Psirens, it was revealed that the crew spent 200 years in deep sleep while tracking Red Dwarf. This appears to have been forgotten.
Revealing mistake: After the crew transport themselves out of the book depository to escape the FBI, the astronaut helmet is transported afterwards and the two FBI agents start shooting at the box the helmet was placed on. When the box is shot, there are no bullet holes left on it.
Timeslides - S3-E5
Factual error: The newspaper detailing the bomb attack on Hitler lists the date as "Tuesday May 4 1938." May 4th, 1938 was a Wednesday. (00:09:15)
Answer: Presumably he does, but it's never been used in any material related to the show. He is the only Cat left (as shown in Series 1), so even if he had once had a name, nobody would know it.
