Sarcophagus - S3-E9
Continuity mistake: The little plastic dome Tarrant places on the alien artifact, connecting it to Orac, disappears when the object begins to disintegrate. (00:24:25)
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.
