Blake's 7 (1978)

Time Squad - S1-E4

Continuity mistake: During Blake's first encounter with Cally, the smudges on the front of his tunic (including a big chalky footprint left by her boot) disappear, reappear and rearrange themselves several times between shots. (00:31:20)

Cygnus Alpha - S1-E3

Continuity mistake: When Vargas beams up to the Liberator just ahead of Blake, Gan & Vila, he challenges them when they arrive from the other side of the room - by stepping out of the teleport bay. But they're standing in the teleport bay, and Liberator has only one. So exactly where is Vargas standing? (00:48:15)

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.

Orbit - S4-E11

Trivia: After a homicidal Avon failed to find Vila aboard the shuttle, footage in which Vila emerged in tears was cut from the final version of this episode. (Only a few seconds of it remains.) The emotional scene was deemed "too intense" for the younger viewers.

Stardrive - S4-E4

Trivia: The box-like entrances to the underground lair proved problematic for the Space Rat actors. When several of them were supposed to spill out on cue, the box walls and their heavy helmets prevented them from hearing the director, who repeatedly screamed "Action!" to no avail. A lone voice from inside the box eventually shouted back, "Can't hear you!"
