Dame Diana Rigg, one of Britain's most esteemed actresses, has died from cancer at age 82. In the course of her career, Rigg conquered the mediums of stage, screen and television. She studied at the Royal Academy of Dramatic Arts in London and received praise for her work in classic theater. Perhaps improbably, she became a pop culture icon when she replaced Honor Blackman on the iconic British TV series "The Avengers" in the 1960s. When Blackman left the show to star as Pussy Galore in the 1964 James Bond film "Goldfinger", Rigg introduced the character of Emma Peel, playing opposite Patrick Macnee's John Steed. She became the most notable early female action star on television, practicing martial arts and often attired in provocative leather outfits. In 1969, Rigg followed in Honor Blackman's footsteps by appearing as the female lead in a James Bond film, "On Her Majesty's Secret Service" opposite George Lazenby's 007. The film, considered one of the best of the series, cast Rigg as a countess who marries James Bond, only to be murdered on their wedding day. The movie was notable for its realistic and downbeat ending. Rigg's other feature films include "The Hospital", "The Great Muppet Caper", "Evil Under the Sun" and "Theatre of Blood", a comedic horror film in which she and Vincent Price were memorably co-starred. She thrived on television over the decades, gaining numerous Emmy and BAFTA nominations and winning an Emmy in 1997 for her performance as the evil Mrs. Danvers in "Rebecca". She also won acclaim for her role in the TV production of "Mother Love" opposite David McCallum in 1989. Rigg found late career success on television with an Emmy-nominated role in "Game of Thrones". In theater, she often concentrated on the classics, packing houses on Broadway and the West End. She won a Tony Award in 1994 for her starring role in "Medea".
