Blake's 7

Ultraworld - S3-E10

Plot hole: When Ultraworld first shows up on the Liberator's screens, all scans show it isn't there. Avon explains it can't be detected because it is an artificial planet using alien technology which blocks all electromagnetic radiation from escaping. But the crew are looking at it on their screen - the ordinary visible light we use to see things is part of the electromagnetic spectrum too.

The Web - S1-E5

Revealing mistake: The double-bladed axe one of the Decimas uses to attack the station windows is wobbling as he strikes with it. Small wonder he's not getting far at breaking in, with a weapon made of rubber. (00:22:30)

Blake - S4-E13

Trivia: It's not every day you can shoot your wife in front of millions of witnesses and get away with it. Klyn, the woman behind the console who sounds the alarm before Avon shoots her, was played by Paul Darrow's real-life wife, Janet Lees Price.
