Redgrave made her professional debut in 1962, as part of the cast of A Midsummer Night's Dream at the Royal Court Theatre. In 1966, she became a film star as the star of "Georgy Girl."
Ms. Redgrave trained in London's Central School of Speech and Drama. She made her West End debut at the Haymarket, in N.C. Hunter's The Tulip Tree. During this time, she began appearing in films such as "Tom Jones" in 1963. As such, she become a movie personality before her sister Vanessa. She did not, however, find the experience entirely pleasurable. "Looking at my horrible ugly bulk on a huge screen was the turning point in my life," she said later.
She was perhaps the most visible of the Redgraves to American audiences, owing to her starring role in the television sitcom "House Calls" (1979-81) and her role as a spokesperson for Weight Watchers weight loss foods. The line she spoke in those commercials, "This is living!" later became the title of her autobiography.
Beginning in the 1990s, she began to refocus her attentions on the stage. She became a member of Tony Randall's National Actors Theatre, which presented classics such as Feydeau and Ibsen on Broadway. With her sister Vanessa, she returned to the London stage playing Masha in Three Sisters in 1991 at the Queen's Theatre, London.
In the fall of 2008, she performed Off-Broadway in her own Nightingale, her solo show inspired by the life of her maternal grandmother, at Manhattan Theatre Club. Nightingale was the most recent in a series of self penned, one-person shows that saw Ms. Redgrave examine the members of her celebrated family members. Shakspeare for My Father was about Michael Redgrave, the head of the family, and Rachel and Juliet was about her mother, Rachel Kempson. Her mother was also the inspiration of Ms. Redgrave's play The Mandrake Root.
