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)
Plot hole: Avon drills the last hole through the bomb's tubing and then, with the drill still in place, has to hunt down the dropped rod needed to block the plunger. Tense drama ensues while it's found and inserted, though simply leaving the drill bit in there would have worked just as well. (00:44:55)
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.
Plot hole: Travis, dressed up as the supposedly disabled dissident Shivan, fools Blake and the rebellion leaders far too easily. His head bandages completely cover his mouth (how did he eat?) and his glued-on glass eye is so obviously fake it's laughable. If we noticed, why didn't they? (00:21:05)
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)
Revealing mistake: Blake hands Cally a photo of Docholli, supposedly obtained from Zen. It's a publicity still of the actor that's not only in black & white (how low tech), but Cally has to hold her thumb rather conspicuously over the very 20th Century necktie he's wearing in the photo. You can see a bit of it anyway. (00:02:15)
Revealing mistake: When he sits on the floor in front of Servalan, Jarrier's earring falls off. He fumbles at it briefly, and then the actor breaks character for just a moment, glancing nervously at the camera. When it's apparent there won't be a retake, he goes on with his lines. (00:16:10)
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)
The Keeper - S2-E12
Revealing mistake: Goth's primitive inhabitants are pre-industrial. They wear furs, use swords and other ancient weapons, and live in tents. So where do they come by their shiny black plastic ski goggles? Goth-mart? (00:07:25)
The Keeper - S2-E12
Visible crew/equipment: During the fight in the banquet hall, the spikes on Gola's mace bend several times, most obviously when he falls back onto the pillows. Must be tough bashing your enemies' skulls in with a foam rubber weapon. (00:44:05)
