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: 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: The molecularly miniaturized Orac has been hidden in a metal box while Avon & Vila smuggle him into the casino. Back on the ship, Orac returns to his normal size, but the metal case around him doesn't get larger too - it instantly disappears. (00:50:15)
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)
Deliverance - S1-E12
Continuity mistake: Meegat peeks at the rocket through the oval space Gan has cleaned on the dirty glass. The shape of this space changes dramatically when the camera angle switches to the other side of the pane. (00:39:15)
City at the Edge of the World - S3-E6
Continuity mistake: Dayna's outfit is skin-tight and she's not carrying any sort of backpack. So just where was she hiding that rather large robotic bomb she sends down the hall to blow up Bayban's goons? (The pack on her belt isn't a storage pouch - it's the Liberator handgun's power unit. Note that Avon, Tarrant and Cally wear identical packs, with the guns plugged into them. And it isn't large enough to hold the mobile bomb anyway, not even disassembled.) (00:35:10)
Continuity mistake: The XK72 space station has a distinctive shape, with a large ringed aft section that's to the right of the screen every time we see it. Liberator is moving past that section at the end, passing on the right. But in the next shot, the ship is abruptly heading away from the station, which is still in the same position, and flying left, in the opposite direction. (00:47:15)
Continuity mistake: Villa is carrying Orac and Soo Ling is about to play the quick draw game, cut to the bridge and Dana walks over to the captain's chair to contact Avon and the top of Orac can be seen in front of her.
Continuity mistake: After revealing Avon & Soolin are still alive, there is no magazine in Avon's gun.
Continuity mistake: Dayna plants the grenade by the right-hand upright of the ladder. Yet when it detonates you can see the blast is to the left and in front of the guard; presumably to prevent it from going off right in the stuntman's face.
Continuity mistake: During the punch-up with Cancer, Tarrant's holster is missing.
Continuity mistake: When they shoot open the crate containing the gold, Avon is on the left & Keeler on the right. Avon fires and we see the right-hand lock explode, then Keeler shoots and the left-hand lock pops.
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.
Ultraworld - S3-E10
Continuity mistake: When Dayna & Tarrant are "bonding" they are not wearing their gun belts. Yet the shot of them running down a corridor immediately after escaping shows Dayna has hers on. In the next scene, it's gone again. Later Avon & Tarrant recover three gun belts from the control room.
Continuity mistake: Cally's hair is longer & curlier in the film sequences (on the planet) than in the studio sequences (on the Liberator).
