Sarah Sutton

Sarah portrayed the character of Nyssa, a Trakenite aristocrat, in Doctor Who. She is exactly one week older than her co–star, fellow companion Matthew Waterhouse. Her first appearance in the role was in the 1981 serial The Keeper of Traken. Initially, Nyssa was intended to appear only in one story, the production team later deciding to keep her as a continuing character. After joining the Fourth Doctor Tom Baker in the subsequent story Logopolis, her final full Doctor Who serial was with the Fifth Doctor Peter Davison, in 1983's Terminus.

Sarah reprised the role of Nyssa in the 1993 Doctor Who Children in Need special Dimensions in Time, and since 1999 has appeared in multiple spin-off Doctor Who audio plays produced by Big Finish Productions. In November 2013 she appeared in the one-off 50th anniversary comedy homage The Five(ish) Doctors Reboot.
