Revealing mistake: When Liberator moves into view on Servalan's screen and stops, a bad special effects matte causes the stars behind the ship to keep on sliding to the right. (00:21:35)
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)
Revealing mistake: A very poorly executed special effects matte causes the star patterns behind the 3 pursuit ships to slide in opposing directions at the same time. (00:42:35)
Revealing mistake: When the fight begins in the detention block and the trooper runs away from Jenna down the hall, two large blaster holes appear in the wall he runs toward - before the first shots are fired. (00:34:45)
Revealing mistake: Scorpio is attacked upon entering Gauda Prime's atmosphere. The ship lurches left: everyone leans left and hangs on. The ship lurches right: everyone leans right and hangs on. The ship rolls over a full 360 degrees: no one leans or hangs on, nor do they fall out of their unbelted flight chairs. And oddly, those same chairs that held fast here tip over with ease later, when Avon escapes with Orac. (00:13:45 - 00:16:15)
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)
Revealing mistake: A bad effects matte causes one of the two ships approaching Xenon to partially dissolve along the way. (00:03:55)
Headhunter - S4-E6
Revealing mistake: When Avon pushes a button to call Tarrant, the entire control panel tips upward, revealing that it's not anchored to the console at all. (00:12:50)
Revealing mistake: When the "phibian" lizard creature attacks Servalan, note the claw that grabs her leg: it is obviously made out of soft fabric and visibly bends as it latches on. (00:24:05)
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)
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)
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)
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)
Revealing mistake: While Avon is occupied in hand-to-hand combat with a native on the beach, someone who isn't supposed to be in the shot can be seen walking on the ridge in the background, waving his arms in the air. (00:13:35)
Revealing mistake: Scorpio is in stationary orbit over the planet Malodaar - but a shaky special effects matte causes the "stationary" ship to wiggle and wobble severely. (00:00:45)
Revealing mistake: At the end, when Tarrant is beamed out, Servalan's position shifts considerably, even though she's supposedly standing still. (00:43:45)
