Continuity mistake: When Kryten decides to be a mechanoid again, Lister gets up and grabs his jacket and swings it around his shoulders. The camera cuts to Kryten for a second then back to Lister, who now has his jacket on fully. The amount of time the camera was away from Lister would make this impossible for him to put the jacket on that quickly. (00:22:15)
Continuity mistake: When The Cat does his dance with Blue Midget, he stands behind one of the legs of Blue Midget and changes his clothes. The old clothes he throws on the ground when changing disappear in the wide shot of the landing area. (00:08:55)
Continuity mistake: In the scene where Lister is talking to human Kryten, just before Lister sees the photos, keep an eye on Lister's hat. It is perched on top of his head with about an inch of hair showing, yet the next shot shows the hat covering all of the hair, then it goes back to an inch of hair showing again. There is no time for Lister to have adjusted his hat between cuts. It is clear the line had to be re-shot. (00:12:35)
Continuity mistake: As the crew enter the game, Lister pushes the door to the beach open. However in the next shot, the door is opening from the other side, i.e. Lister is pulling the door. (00:16:10)
Continuity mistake: In the quarters of the female versions of the crew, the newspaper clippings and certificates on the wall still have the name 'Arnold' on them, and not the female equivalent, as it was supposed to be. (00:23:15)
Other mistake: In the picture of the cat wars between the Red Hats and the Blue Hats, the hats are orange instead of blue. (00:19:00)
Continuity mistake: When Kryten tells Kochanski he doesn't have a penis, he turns away from her. In the next shot you can still see Kryten on the right of the screen as he turns away from her again. (00:07:20)
Continuity mistake: When Lister puts his Better Than Life helmet on, the cable is hanging over his right shoulder. In the next shot it is hanging down over his left shoulder. (00:15:45)
Continuity mistake: When the bike appears on the beach, the front tyre is above the level of sand. In the next shot it has sunk by about an inch. (00:17:50)
Continuity mistake: The sand that lands on Rimmer's shoulder when Lister and the Cat drive away on the bike disappears in the next shot. (00:18:10)
Continuity mistake: When Kryten's head falls off it bounces with no velocity, yet in the next shot it is quickly rolling out of the door. (00:06:55)
Revealing mistake: During the 'Two Listers' scene, specifically the cut when Kryten tosses the apples to the Listers, the split screen is quite visibly moving in between the chairs. (00:22:55)
Continuity mistake: When Lister swings the axe at The Cat and hits the door frame, the axe head bends. When Lister pulls the axe out, its head is fine again. (00:22:30)
Answer: It's Queen Victoria, someone any Englishman would recognize, and needed no introduction.
