Headhunter - S4-E6
Continuity mistake: Muller and Vila have a brief struggle over the teleport console. When Muller grabs at the controls, Vila pulls his hand away, making the teleport lever break off and fall onto the console. It fixes itself again a short time later. (00:06:05)
Continuity mistake: Cato's body moves to a different spot on the floor relative to the unconscious Avon, who also moves. (The two are suddenly much farther apart than before.) Cato's hands also change positions. (00:31:40 - 00:35:00)
Headhunter - S4-E6
Continuity mistake: Muller's wife teleports holding her spacesuit gloves with the fingers pointing up. She arrives with them in the same position, but when the shot cuts, they've reversed positions and the fingers are now pointing down. (00:28:40)
Continuity mistake: When Jarvik and Dayna teleport up at the end, her bracelet disappears as they materialize in the teleport bay, but is back when they reach the flight deck a few seconds later. (00:44:30)
Headhunter - S4-E6
Continuity mistake: Relative to the white striping on Scorpio's deck, the unconscious Vila changes locations on the floor three times between shots. (00:21:10)
Continuity mistake: When Dayna and Tarrant find Keeler unconscious, Tarrant's teleport bracelet disappears between shots. It's back a few shots later, though. (00:15:40 - 00:16:10)
Sarcophagus - S3-E9
Revealing mistake: When Tarrant, trying to call Dayna, falls against the flight deck console, the whole thing tilts visibly. (00:38:45)
Continuity mistake: Avon refers to Tarrant hitting him "over the back of the head." But Tarrant didn't. He struck Avon from the front, on the forehead, and not from behind. (00:05:30 - 00:40:45)
Revealing mistake: As Liberator approaches it, the planet changes color. (00:08:05 - 00:13:40)
Continuity mistake: The Liberator gun Avon uses to kill two of the three troopers on the flight deck disappears entirely between shots after he's hit by the third trooper's return fire. (00:33:50)
Visible crew/equipment: When Jenna tries to call Gan and Vila from her flight deck station, part of a piece of equipment is sticking out into the lighted corridor to her left. It's still there later, when Gan walks through the opening, but it's gone a short time later. (00:06:45 - 00:13:15)
Factual error: Zen refers to the objects encountered at the beginning of the episode as "meteorites". In space, these objects are known as meteoroids. When they enter the Earth's atmosphere they are called meteors, and when they hit the surface of the earth they are called meteorites.
Ultraworld - S3-E10
Factual error: The Ultra may be expert collectors of knowledge, but they have their facts wrong about Avon, who tried to steal 5 million credits from the Federation banking system. The Ultra think it was 500 million. (00:10:05)
Headhunter - S4-E6
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)
Factual error: Servalan's ship takes off from the surface of Bucol 2 with Avon and crew standing directly below it. Yet for some reason, the down-blast from the very large launching ship does nothing more harmful than slightly mess up their hairdos. (00:47:50)
Factual error: Liberator's medical treatments are certainly weird. Vila dresses Avon's wounded arm with padding that's put on over top of his clothing. (00:37:20)
Visible crew/equipment: The boom shadow forms a distinct outline on the control console next to Vila when the crew are discussing Space City and the Terra Nostra. (00:04:40)
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.
