Continuity mistake: In George's memorial service, the extras are totally different in the shots from George's point of view to the shots from the back of the room. Look for the woman with brunette hair and orange overalls - she's there in the forward shots but missing in the reverses. The chairs, tables, props, costumes and character placements are all completely discontinuous. (00:12:15)
Audio problem: When Lister and Rimmer see Cat just after Holly explains how he evolved, Rimmer runs at Cat screaming before he passes through him and we hear a crash off screen to indicate Rimmer has just run in to something. He is a hologram and is not solid, so no sound should be heard. [The original version did not have this mistake. The sound effect was added for the now defunct Remastered series.] (00:27:10)
Continuity mistake: At the start of the 'Welcome Back George McIntyre' reception scene, Lister, Chen and Selby are throwing things at Rimmer, then Rimmer looks around. In the next shot, Lister and Chen are looking round to their left, Selby is stabbing between his fingers, Rimmer is now looking straight forwards and Petersen has appeared from nowhere. (00:09:40)
Continuity mistake: When George McIntye finishes his speech, he is standing. When the camera cuts back, he is sitting down. (00:11:55)
Continuity mistake: Half way through the episode, the captain's office becomes covered by a wall. (00:24:55)
Continuity mistake: When Lister takes the milk from his locker, keep an eye on his duvet. In the next shot when he pours the milk, it has moved and is hanging down from his bunk. The red mug on the table also moves from near the magazines to near the ashtray on the other side of the table. (00:14:35)
Answer: It's Queen Victoria, someone any Englishman would recognize, and needed no introduction.
