Behind the scenes

 * Mary Farrel's first name is not used in the on-screen dialogue of Terror of the Autons, and Barbara Leake is credited as "Mrs. Farrell [sic]" on the closing titles of episodes two and three. (The correct spelling of "Mrs. Farrel" appears in Radio Times.) It is only mentioned in Terrance Dicks's novelisation, Doctor Who and the Terror of the Autons.
