Sarcophagus - S3-E9
Revealing mistake: When Tarrant, trying to call Dayna, falls against the flight deck console, the whole thing tilts visibly. (00:38:45)
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.
Ultraworld - S3-E10
Factual error: The Ultra may be expert collectors of knowledge, but they have their facts wrong about Avon, who tried to steal 5 million credits from the Federation banking system. The Ultra think it was 500 million. (00:10:05)
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.
Ultraworld - S3-E10
Other mistake: Avon tells Vila to open the starboard airlock, but the exterior shots of the Liberator show there is nothing attached to the starboard side of the ship.
Ultraworld - S3-E10
Continuity mistake: When Dayna & Tarrant are "bonding" they are not wearing their gun belts. Yet the shot of them running down a corridor immediately after escaping shows Dayna has hers on. In the next scene, it's gone again. Later Avon & Tarrant recover three gun belts from the control room.
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)
Visible crew/equipment: As Servalan begins explaining her nefarious plan to the captured Avon, an equipment shadow slides across the blue diamond-shaped pane just behind her. (00:40:30)
Revealing mistake: To conceal their unauthorized entry into the secret lab, Cally very carefully closes and locks the sliding door. But when she turns back to speak with Tarrant, the "secured" door rolls halfway back open by itself. No, it's not Servalan's troops sneaking in to catch them: there's no sign of anyone there. Besides, anyone unlocking the supposedly-locked door would have alerted them. A case of malfunctioning BBC scenery, plain and simple. (00:43:45)
Plot hole: If the "Enzyme Activity" adhered to the hull of the Liberator, how did it enter the ship without causing a hull breach and immediate loss of pressure ? Also, how did Servalan not suspect anything when she boarded, missed Orace and ordered Maximum Power surrounded by green mould?
