Production Notes[]

  • Though the second story of season two, The Mutant Phase was the first to be recorded.
  • This story features Liz Knight's only appearance in the role of Ria. Patricia Merrick played her in the character's first story, Maenad, because it was recorded after this one.
  • Jim Mortimore provided the incidental music for this story after its original composer, Brian Marshall, only managed to deliver five minutes worth for episode one.
  • Though originally meant to be recorded alongside the rest of the cast, the temperamental nature of the ring modulator meant that a second session was required to record the Dalek voices.
  • The opening scene was written and recorded during the Dalek session.
  • This story was remade by Big Finish Productions as part of their monthly range releases and part of the Dalek Empire series. This version featured the Fifth Doctor and companion, Nyssa.
