Continuity mistake: The weather on Terminal has changed from Summer to Winter overnight. When Avon first beams down, it's obviously warm and all the trees have leaves. The very next day, all the trees are bare and there's snow all over the ground. (00:01:30)
Continuity mistake: Avon apparently found a hair salon somewhere on the supposedly deserted planet Terminal. Between the time he and his crew were marooned in the previous episode and the events in this one, he's suddenly acquired a spiffy new blow-dry haircut. (00:03:10)
Continuity mistake: Vila makes an improbable costume change in this episode. He's wearing one outfit at the end of "Terminal," when Liberator is destroyed, and another outfit entirely here, where he's supposedly marooned on the planet with the remainder of the crew. Did he take time to smuggle a spare set of clothes off the ship, even though it was disintegrating at the time? (00:03:30)
Continuity mistake: The planet Terminal changes shape and color completely from its appearance in the previous episode. Where it was blue-green and cigar shaped before, it is now gray, striped like a yarn ball, and round. (00:07:00)
Continuity mistake: Tarrant's hair seems to have grown at least an inch overnight. It's longer and bushier than it was in "Terminal," which supposedly took place the day before. (00:09:45)
Continuity mistake: The damaged Orac has long loose wires hanging out when Dorian carries it off the ship, but they disappear in the next shot, when he enters the base. (00:24:40)
Continuity mistake: After Scorpio has landed on Xenon, the lift rotates 180 ready for launch. Yet after Pella boards the ship, it is seen rotating again.
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)
Continuity mistake: At the end, Dayna and Tarrant, shortly followed by Soolin and Vila, all teleport to Scorpio without wearing the necessary bracelets. (00:47:35)
Continuity mistake: The president-elect's body changes both poses and locations on the floor between the time Sleer shoots him and the time he's found and the murder investigation is begun. (00:26:00 - 00:31:25)
Continuity mistake: Tarrant and Dayna mug a pair of Helotrix citizens and change clothes with them. Later, when the pair are beamed back to Scorpio, they change back into their original costumes in mid-teleport. (00:44:05)
Continuity mistake: Maybe he ran into a barber along the way? Avon beams into the woods on Bucol 2 with his hair brushed straight back, but a few shots later, it's restyled and combed neatly down over his forehead. (00:43:35 - 00:44:45)
Continuity mistake: When Avon & Co. barnstorm the ruined lab, a large piece of plastic debris on the floor is there when they enter, but then disappears between takes. Avon actually slips on it coming in, and does a hilariously un-macho little balancing dance. To quote (and agree with) actor Paul Darrow: "I can't believe they left that in!" (00:45:00)
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)
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)
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)
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)
Continuity mistake: During the punch-up with Cancer, Tarrant's holster is missing.
Continuity mistake: The computer simulation shoots Gerren in the left shoulder, but when the Scorpio crew teleport him up to let Soolin render first aid, he's holding his right shoulder instead. (00:06:30 - 00:08:00)
Continuity mistake: Orac is in two places at once: he's sitting on the console, plainly visible in front of Dayna as she calls the landing party - but in the next shot of the crew over on the orbiter, Vila is holding Orac. (00:40:45)
