Dame Enid Diana Elizabeth Rigg, DBE (20 July 1938 – 10 September 2020) was an English actress.
Diana Rigg appeared in the British 1960s television series The Avengers (1961–69) opposite Patrick Macnee as John Steed, playing the secret agent Emma Peel in 51 episodes. Rigg auditioned for the role on a whim, without ever having seen the series. Although she was hugely successful as Emma Peel, she disliked the lack of privacy that it brought and she was also not comfortable in her position as a sex symbol.
She had a long and varied film career, playing Countess Teresa di Vicenzo, wife of James Bond, in On Her Majesty's Secret Service (1969) and Olenna Tyrell in Game of Thrones (2013–17) to name but two.
She also enjoyed a career in theatre, including playing the title role in Medea, both in London and New York, for which she won the 1994 Tony Award for Best Actress in a Play. She was made a CBE in 1988 and a Dame in 1994 for services to drama.
