Redemption - S2-E1
Revealing mistake: As Avon and the crew run through the station and the guard tosses a grenade at them, you can see the white packet of incendiary charges on the floor that will set off the grenade's explosion. (00:42:30)
Revealing mistake: When Bek pulls the silver shroud off of Petey, note the movement on the chest of the corpse, which is obviously breathing. (00:08:30)
Visible crew/equipment: In one shot of the Liberator's flight deck near the very end, there's a BBC workman's toolbox visible, sitting under one of the control consoles. (00:46:25)
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: Jenna's bracelet changes from her right to her left wrist in mid-teleport when she and Blake go down to the planet. (00:10:00)
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)
Other mistake: On the flight deck, when Vila says he can't remember anything "between meeting Largo and waking up back on the ship," Bek, sitting behind him, starts his next line too early, stops and waits for Vila to finish, then says it again. (00:30:30)
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)
Factual error: Servalan's space station is shown rotating at a fairly fast clip. But the stars in both her office window and in the courtroom window are stationary. Because the station is spinning much faster than a planet's normal rotation, the stars should be visibly moving. (00:00:35 - 00:03:10)
Factual error: Avon and Vila watch the rocket launch from the surface of the planet. The rest of Liberator's crew also watch it from the flight deck, and somehow their view from orbit is at exactly the same angle from which Avon and Vila are seeing it: a ground-to-air shot. (00:03:15)
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)
Redemption - S2-E1
Deliberate mistake: In the escape scene near the end, an explosive charge that went off too soon knocked Paul Darrow over - and briefly out of the shot. Because he was able to get back up and keep running, the accident was left in, though he's said it was fortunate there was no microphone on him at the time, as he uttered a few words that were "definitely not rated PG." (00:42:30)
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: Provine shoots the rebel guarding the rocket in the chest. But later, when his body is found, the man is bleeding from the mouth instead, and the blood pooled on the floor beside him changes from beside his head to above his head between shots. (00:21:10 - 00:42:00)
Revealing mistake: Due to recycled stock footage from "Space Fall," the Liberator leaving Fosforon at the end of this episode still has the prison ship London attached to its hull. (00:49:25)
Revealing mistake: In the control complex, Avon tosses two coin-like objects onto the electrified floor to test the grid. But the "coin" is already on the floor before the sound effect of it landing can be heard, and the mini explosions the coins set off is the same footage both times. (00:38:30)
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)
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)
