Visible crew/equipment: Avon is picking himself up from the computer room floor after a berserk Gan has attacked him. Blake rushes in to say, "Are you all right?" But he's been standing out there in the corridor, blocking a big bright patch of light throughout the scene, only to rush in on cue. (00:26:10)
Blake's 7 (1978)
1 visible crew/equipment mistake in Breakdown - chronological order
Starring: Jan Chappell, Michael Keating, Paul Darrow, Peter Tuddenham
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)
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!"
