Visible crew/equipment: After Avon says, "I haven't been anywhere near them," and sits down on the flight couch, part of the camera dolly moves across the bottom of the screen. (00:06:30)
Deliberate mistake: Because Paul Darrow had turned an ankle while shooting the fight scene with Gunsar, the uninjured Avon is inexplicably limping throughout most of the fight. (00:14:00)
Factual error: Tarrant fails Astronomy 101 here, just as Travis did in the first season. He tells the clerk, "I'm surprised you've heard of it (the FSA), if you're from another galaxy." The Tharn and his minions were not extragalactic; they were from other planets in our galaxy. (00:35:10)
Continuity mistake: During the firefight in the detention corridors, the blaster holes in the metal wall Jenna's firing toward keep changing, sometimes disappearing altogether. One of them is created twice, appearing as the troopers duck out of sight, vanishing and then reappearing in the same spot when Jenna fires again. (00:36:00)
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)
Visible crew/equipment: The "exterior" windows in Blakes 7 are a constant source of amusement. In many cases you can see the top or bottom of the board which is supposed to be the window, with empty set behind the board. Turn the brightness of your screen up to maximum and in many cases you can see that "windows" are semi-transparent perspex with light bulbs for the stars. You can often see wiring running from bulb to bulb, looped and cable-tied together, etc., through the "windows".
Revealing mistake: Liberator's auto-repair circuits have mysteriously stopped functioning. The molding on the top center flight deck console is hanging loose, a glitch that remains for several episodes. (00:23:50)
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)
Space Fall - S1-E2
Continuity mistake: A large white cushion, knocked askew when Blake tosses Avon over the flight couch, has righted itself a few shots later, as Avon gets up from the deck. (00:46:25)
Plot hole: Avon delivers his summation of the crimes and the murderer's identity to the Ortega's crew - with his back turned to the guilty party the entire time. This gives the killer ample time to pull a gun on them. But it's also egregiously out of character for Avon, whose suspicious nature bordered on paranoia and would never have allowed him to be so careless. (00:42:25)
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)
Time Squad - S1-E4
Continuity mistake: The alien hiding in the hold throws a large blue tool at Jenna. It strikes her on the back of her right arm. But in the next shot, she's holding her left arm, and Gan later treats a bruise on her left arm, nowhere near the spot where the tool hit her. (00:27:45)
Deliberate mistake: Because Stephen Greif tore an Achilles tendon playing squash, a stand-in had to complete his scene with Servalan in Ensor's underground complex. The result was a very odd segment in which we hear Travis' voice (pre-recorded by Greif) answering Servalan's lines, but never see him - except for an awkward shot of shuffling, black-booted feet that are all-too-obviously not Greif's.
Visible crew/equipment: While pulling back from Vila's conversation with the gaming computer, the camera apparently runs over a cable. There's a visible jump in the picture and an audible clanking noise. (00:37:20)
Revealing mistake: BBC costume recycling allows one of the natives on Helotrix to show up wearing one of Tarrant's old 3rd season outfits. Another wears an even older, 1st season costume of Avon's. (00:22:40 - 00:24:25)
Continuity mistake: The damaged Orac has long loose wires hanging out when Dorian carries it off the ship, but they disappear in the next shot, when he enters the base. (00:24:40)
Ultraworld - S3-E10
Plot hole: When Ultraworld first shows up on the Liberator's screens, all scans show it isn't there. Avon explains it can't be detected because it is an artificial planet using alien technology which blocks all electromagnetic radiation from escaping. But the crew are looking at it on their screen - the ordinary visible light we use to see things is part of the electromagnetic spectrum too.
Visible crew/equipment: When Blake and the landing party are on the flight deck, preparing to go down to the planet, something black intrudes on the left side of the screen during a shot of Avon on the flight couch. (00:08:50)
