After beginnings in dance and modeling, she turned her attention to acting, and made her American acting debut (and came to prominence in what would be a Golden Globe–nominated role) in her portrayal of Tonya in David Lean's Doctor Zhivago (1965). She made her Broadway acting debut in Lillian Hellman's The Little Foxes in 1967, and received her second Golden Globe nomination for Robert Altman's Nashville (1975). She received a BAFTA nomination for her role in Welcome to L.A. (1976). She played her grandmother Hannah Chaplin in the biopic, Chaplin (1992) for which she received her third Golden Globe nomination.
