Starring: Jan Chappell, Michael Keating, Paul Darrow, Peter Tuddenham
Continuity mistake: Jenna's bracelet changes from her right to her left wrist in mid-teleport when she and Blake go down to the planet. (00:10:00)
Continuity mistake: When the crew teleports up at the end, the shirtless Vila arrives in a completely different position relative to the others. On the surface, he's standing in a ring with the rest of them. When they materialize, he's hunched over and is now in the middle of their circle with the others around him. (00:42:25)
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)
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!"
