And where was Mr. Peel while his wife was saving the UK ? Peter Peel was a pilot whose plane had disappeared flying over the Amazon, and Mrs. Peel was presumed a widow. He returned from the jungle, though, and Emma resumed her married life in Diana's last episode.
Born in England and raised in India, Diana has been regarded as an accomplished actress, building a successful career based more on stage work than Hollywood films. She was made a Dame Commander of the Order of the British Empire for her contributions to theater and film in 1995.
She auditioned for the role "for a giggle," and was horrified to learn after her first season that she was earning less than the cameramen. She staged a short strike and returned to the show after receiving a raise that paid her 10 pounds per week more than the cameramen.
After her two-year stint on "The Avengers," she returned to the stage, and then later played another notable role, that of Countess Teresa di Vicenzo in the James Bond film "On Her Majesty's Secret Service."
