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)
Continuity mistake: At the end of "The Way Back," Blake, strapped in his prison ship seat, looks over his shoulder at the window behind him as the ship leaves Earth. This same scene is recapped at the beginning of "Spacefall," only now Blake is sitting one seat to the left of the window instead of directly in front of it. (00:49:00)
Continuity mistake: During the firefight in the detention corridors, the blaster holes in the metal wall Jenna's firing toward keep changing, sometimes disappearing altogether. One of them is created twice, appearing as the troopers duck out of sight, vanishing and then reappearing in the same spot when Jenna fires again. (00:36:00)
Continuity mistake: The alien hiding in the hold throws a large blue tool at Jenna. It strikes her on the back of her right arm. But in the next shot, she's holding her left arm, and Gan later treats a bruise on her left arm, nowhere near the spot where the tool hit her. (00:27:45)
Continuity mistake: The headless android falls into a pile of rubble after an explosion, getting up with its red, white & blue striped costume in smudgy tatters. A moment later, its outfit is mended and completely clean. Still later, when the android is walking outside, its costume is dirty and shredded again. (00:33:30 - 00:35:00)
Continuity mistake: Liberator's orientation relative to the space station changes. As viewed from inside the administrator's office, the ship is "parked" parallel, with its port side against the station. But in the subsequent exterior view, Liberator suddenly has its bow pointed directly at the station instead.
Continuity mistake: Just before Scorpio crashes, Avon grabs Orac and teleports to safety. When they're still aboard the ship, Orac has several wires hanging loose from underneath. When they materialize on the planet, however, all the loose wires are magically repaired and no longer hanging. (00:16:30 - 00:17:45)
