Plot hole: The IMIPAK weapon marks its victims and then kills them with a secondary device. But it's inconsistently selective. When Servalan kills the guard with it, Blake and co., marked and standing nearby, are unharmed. But Rashel later warns Travis not to push the button because he and Servalan are marked and would die too. (That the weapon's range is "adjustable" is nowhere mentioned or implied. Servalan doesn't change a thing before she fires it). (00:43:55 - 00:46:30)
Continuity mistake: In the final scenes on the planet, Blake's teleport bracelet appears and disappears repeatedly between shots. It reappears the final time just before he snatches it off and tosses it away to avoid being teleported up. (00:44:35)
Factual error: Avon and Grant use an electric torch to melt the ice covering the bomb. When it's removed from its hiding place, it is suddenly completely dry and clean: not a trace of ice, water or dirt on it anywhere. (00:36:00)
Visible crew/equipment: When the clone Blake is asking Coser for the weapon and holding his hand out, the boom mike is visible hanging over his head. (00:36:45)
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)
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)
Revealing mistake: When Veron drops her gun in the ruined church, the noise of it hitting the floor reveals it is made of wood.
Continuity mistake: Cally's hair is longer & curlier in the film sequences (on the planet) than in the studio sequences (on the Liberator).
Other mistake: When Jenna teleports down near the end of the episode, she takes 3 bracelets with her. When they all teleport back up to the ship she still has all 3 bracelets on. Therefore Vila and Avon should not have been teleported up.
Suggested correction: Jenna has 5 bracelets with her, she's wearing 3 and 2 are in her hands. She gives the ones she's holding to Vila and Avon. However, Ushton and Inga decided to stay and not transport back, therefore, she kept the extra 2 bracelets on her wrist.
Character mistake: Much drama ensues from which wire to cut; ("Right. NO, Left!"). However, the wires are coloured (L-R from our viewpoint: blue, red, green). There is no need for this confusion.
