Pauline Collins

Pauline Collins (born 3rd September 1940) played Samantha Briggs in The Faceless Ones and Queen Victoria in Tooth and Claw.

She was heavily solicited to convert Samantha into a regular companion to replace Polly. Despite personal appeals by Innes Lloyd and even Frazer Hines, however, she declined the offer.

According to David Tennant on the DVD commentary for The Idiot's Lantern, she holds the record for the most amount of time between appearances on Doctor Who, narrowly edging Margaret John.

As documentary subject
Collins' views on her time in The Faceless Ones, as well as her memories of being invited to become a companion, were a part of the audio documentary, BBCR: Doctor Who - The Lost Episodes. She was also interviewed about her performance of Queen Victoria in CON: "Fear Factor".
