In 2019, Rigg told the BBC, "There are some actors who don't like to play bad; they like to be liked. I love to be disliked. Olenna had the best lines."

An accomplished stage actress, Rigg broke into television playing Emma Peel on British espionage series The Avengers, a performance that landed her Emmy nominations in 1967 and 1968. All told, she was nominated for nine primetime Emmy awards, winning one for playing Mrs. Danvers in a TV adaptation of Rebecca in 1997.

From 1959-64, she was a member of the Royal Shakespeare Company, where her notable roles included Cordelia in King Lear and Viola in Twelfth Night. She went on to be a member of the National Theatre Company, playing Lady Macbeth in 1972. She played Eliza Doolittle in Pygmalion in 1974, then returned to the play in the role of Mrs. Higgins in 2011.

Rigg was nominated for four Tony awards for her work on Broadway, finally winning for Medea in 1994. Her most recent Broadway performance and final Tony nomination came for playing Mrs. Higgins in the 2018 revival of My Fair Lady.
