Trivia / Big Finish Doctor Who CCS 6 E 7 The Anachronauts

• Acting for Two: Typical of Companion Chronicles, which are essentially audiobooks read by an actor. In this story, Peter Purves plays his character Steven Taylor, and Jean Marsh plays Sara Kingdom, but both also play other characters in addition to simply narrating events. Purves does a good imitation of William Hartnell's Doctor.
• Role Reprise: Peter Purves and Jean Marsh play their Doctor Who characters from back in the 60s, during the third season of the original programme. The characters are meant to be the same age now as they were then, which the actors can just about get away with because of the audio-only format.
