Timeslides - S3-E5
Continuity mistake: During the golf game, Lister's locks move between shots throughout the scene. (00:01:20 - 00:02:20)

Timeslides - S3-E5
Continuity mistake: A blue fan appears on the golf course in the middle of the scene from nowhere. (00:01:30)

Timeslides - S3-E5
Continuity mistake: When Kryten notices the photo of the bike in the countryside is moving, the peg attached to it is near the middle, along the top, but in the shot from behind, the peg is much closer to the right. The same goes for the photo of Kryten's birthday party. (00:03:30)
Timeslides - S3-E5
Continuity mistake: When Kryten first sees the photos, in one camera shot they are moving on the string. In the next shot they are perfectly still. (00:03:40)

Timeslides - S3-E5
Continuity mistake: When the slideshow starts, the photos in Lister's hands disappear between camera cuts. (00:06:20)

Timeslides - S3-E5
Continuity mistake: When we see the photo of the skiers, there are no boxes in front of the screen. When the shot changes, two boxes have appeared which Rimmer and Lister use as steps. (00:07:20)

Timeslides - S3-E5
Continuity mistake: When we see the skiers, no one is standing in front of the screen. In the next shot, Lister has appeared from nowhere. (00:07:20)

Timeslides - S3-E5
Revealing mistake: When Lister is hit in the face with the snowball, some of the snow lands on Rimmer's hologramatic uniform. (00:07:40)
Timeslides - S3-E5
Deliberate mistake: The Eagle on Hitler's briefcase is that of the (post war) Federal Republic of (West) Germany - not that of the Nazi German Third Reich. This was deliberate - showing the Third Reich Nazi emblem of an eagle holding a swastika would have had the episode banned in Germany, Austria, Poland and any number of other European countries. (00:08:25)
Timeslides - S3-E5
Continuity mistake: When Lister is looking through Hitler's briefcase, he finds a banana and crisps sandwich with a bite taken from it. When Rimmer takes a bite out of the same sandwich later in the episode, the sandwich is whole. (00:08:30 - 00:26:15)
Timeslides - S3-E5
Factual error: The assassination attempt on Hitler in 1944 was in Rastenburg, not Nuremberg as stated in this episode. (00:08:50)
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)

Timeslides - S3-E5
Continuity mistake: We are told that it is impossible to move outside the frame of a slide, yet when we are shown the slide of young Lister and his band, all we see is the band on stage but the crew move freely about the pub. (00:11:40)
Timeslides - S3-E5
Audio problem: In the photo of 'Smeg and the Heads' you can see that the drummer frantically plays the cymbals, but no sound comes from them. (00:11:40)
Timeslides - S3-E5
Continuity mistake: In the pub, Lister gets a pint incredibly quickly after they arrive and has managed to drink half of it in a single camera cut. (00:11:50)
Timeslides - S3-E5
Continuity mistake: Kryten needs to ask what a pub is, yet in the episode "Backwards" he and Rimmer worked in one for three weeks as the comedy act "The Sensational Reverse Brothers", and, later, were involved in a brawl in the same pub. Originally, the episodes were to be shown in a different order, which explains why the mistake occurs, but doesn't excuse it. (00:12:55)
Timeslides - S3-E5
Continuity mistake: When Lister and Gilbert are looking at the statue of Lister in the courtyard, Lister has his arms crossed in an angle from above, but when the shot cuts back, his arms are at his side, before crossing them again. (00:19:25)

Timeslides - S3-E5
Revealing mistake: When Rimmer dies at The End of the episode, a dummy is visible just before the explosion. (00:26:40)
Timeslides - S3-E5
Factual error: The writer's understanding of the history of Nazism and its leaders is a bit shonky. Claus von Stauffenberg did not plant a bomb in Hitler's briefcase - he put it in his own briefcase which he planted in a meeting room next to Hitler (some berk moved it). This was in July 1944, while the last Nuremberg rally - which Lister visits, bringing back the briefcase - was in 1938. Stauffenberg didn't even join the anti-Hitler conspiracy until 1943. Red Dwarf is not an 'alternate history' - they correctly identify elements of the Stauffenberg plot and the Nazi regime, they just get them wrong.
Suggested correction: It's not a documentary. This is the history of the universe in which Red Dwarf is set. It's almost as if it's a Parallel Universe.
Read the posting again - Red Dwarf is not an "alternative universe."

Continuity mistake: When Rimmer visits rich Lister, he apears from a point right next to him. But when he leaves, the point at which he disappears is much furthur back.
