Redgrave's turn as a chubby, childlike Londoner pursued by her father's middle-aged boss (James Mason) won her an Oscar nomination for best actress and the New York Film Critics Circle Award. She garnered another Academy Award nomination for supporting actress in "Gods and Monsters" (1998), playing a testy housekeeper.
Redgrave hailed from a venerable theatrical family. She was the younger sister of actress Vanessa Redgrave and actor Corin Redgrave and the daughter of Michael Redgrave and Rachel Kempson.
Her death comes a year after her niece Natasha Richardson died from head injuries sustained in a skiing accident and just a month after the death of Corin. Redgrave was diagnosed with breast cancer in December 2002, had a mastectomy in January 2003 and underwent chemotherapy.
