City at the Edge of the World - S3-E6
Continuity mistake: The probe Vila uses to collapse the door's forcefield vanishes when the forcefield actually collapses. (00:24:05)
Plot hole: Ordered to kill him, the Federation squadron stakes Avon down - on a sand dune. Naturally, he has no trouble pulling loose and clobbering them all. This is hardly just a "character choice": it's a plot hole the size of Tuskeegee. A trained military unit (which they were) would never be so stupid. They could simply have shot him with no difficulty whatsoever. (00:33:30)
Continuity mistake: The computer simulation shoots Gerren in the left shoulder, but when the Scorpio crew teleport him up to let Soolin render first aid, he's holding his right shoulder instead. (00:06:30 - 00:08:00)
Revealing mistake: When Scorpio flies from its launch bay cut in the Xenon cliff face, it's broad daylight (and no, the planet does not have twin suns) - but the ship casts a shadow on the cliff above itself. There's no possible light source from that angle other than studio lights on the ship model. (00:01:20)
Plot hole: When the warlords lift their glasses in a toast, the same mysterious blue electrical arcs, which later appear and kill everyone in the freight bay, spark and sizzle around their hands. But for some strange reason, no one seems to find this at all peculiar. (00:11:15)
Headhunter - S4-E6
Revealing mistake: After its "borrowed" head is blown off and it rampages through the base headless, the android mysteriously gains 10 inches in height and has much longer arms. If they'd just found a shorter actor to wear the headless costume, it might have looked more convincing. (00:44:05)
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)
Visible crew/equipment: When Jenna asks Gan to keep trying voice contact with the unidentified ship, the boom shadow is distinctly outlined on the control console to the left of the shot. (00:08:00)
Continuity mistake: In his scuffle with Servalan's trooper, Vila's teleport bracelet falls off and rolls away. We're even shown a close-up of it as it comes to rest near the dropped gun. Yet in the very next shot, as the fight continues, the bracelet is back on Vila's wrist. (00:37:20)
Revealing mistake: When Blake hastily slaps at the oxygen vent control to close it, the knob breaks off, drops to the floor and bounces noisily away. (00:07:25)
Continuity mistake: As the ship falls into the black hole, Cally loses consciousness with her right hand beneath her head. A few shots later, her position reverses and she's lying with her left hand under her head. (00:10:40 - 00:11:35)
Factual error: Tarrant is some pilot. He miraculously gets the LEM into orbit without any rocket boosters or propulsion system of any kind - and with its landing gear still attached. (00:46:50)
Sarcophagus - S3-E9
Revealing mistake: Peter Tuddenham was the talented voice behind most of the Blake's 7 computers - Zen, Orac & Slave in particular. In "Sarcophagus," Zen is under attack from the telepathic alien mind brought aboard, and its voice changes pitch, rate and timbre as it struggles to ward off the attack. During many of these moments Zen sounds exactly like Orac or Slave, since normally those computers' voices are Peter with the same type of pitch/rate tricks anyway.
Revealing mistake: The dead man, shot by the game computer in the orbiter's corridor, is still moving his fingers, and later moves his arm from resting on his chest to flat on the floor. (00:06:05)
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)
Continuity mistake: Maybe he ran into a barber along the way? Avon beams into the woods on Bucol 2 with his hair brushed straight back, but a few shots later, it's restyled and combed neatly down over his forehead. (00:43:35 - 00:44:45)
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)
