Behind the scenes

 * Samantha was originally intended to become the Second Doctor's companion at the end of The Faceless Ones, but Pauline Collins turned down the offer to become a series regular. In her absence, Victoria Waterfield from the following story, The Evil of the Daleks, was chosen as the next companion. The production crew had also considered Mollie Dawson as a companion.
 * Pauline Collins returned to Doctor Who for Tooth and Claw, in which she played Queen Victoria.
