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)
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: When Veron drops her gun in the ruined church, the noise of it hitting the floor reveals it is made of wood.
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: 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)
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)
