Sarah Sutton

Sarah Sutton(born 12 December 1961) played Nyssa in Doctor Who from The Keeper of Traken to Terminus, as well as Nyssa's doppleganger Ann Talbot in Black Orchid. She also made a cameo appearance as Nyssa in The Caves of Androzani and reprised the role in the thirtieth anniversary special Dimensions in Time.

Nyssa was a companion of the Fourth and Fifth Doctors from 1981 to 1983. She was notably only nineteen when her first story aired, making her one of the youngest main actors to date, surpassed only by Matthew Waterhouse, who she worked alongside until 1982. Although Sutton left full-time acting after her time as Nyssa, she has since performed this role in several of the Big Finish Productions Doctor Who audio dramas and played an unrelated role in a Doctor Who universe audio drama by BBV Productions.

Prior to Doctor Who, Sutton appeared on other television programmes, including (1974) as Alice (a role which Deborah Watling also played) and as Diana Purwell in  (1978), written by Doctor Who writer Brian Hayles, in which she managed the difficult task of playing a blind girl throughout the entire serial. She also appeared in The Crucible (1980) as Susannah Walcott.
