Born Diane Hall in Los Angeles. Offbeat leading lady of Hollywood films from the 1970s. The daughter of a civil engineer and a photographer mother, at 19 she quit a Santa Ana junior college after three semesters to study acting at New York's Neighborhood Playhouse. Somewhere along the line, she sang and danced with a rock group. After several months of summer stock at Woodstock, she joined the cast of the Broadway musical Hair as a supporting player and understudy for the lead and in 1968 took over the starring role. The following year she played the lead opposite Woody Allen in the Broadway production of Play It Again, Sam. For several years, she was Allen's romantic companion and in the 70s played in a number of his films, notably ANNIE HALL (1977), for which she won the best actress Academy Award, and MANHATTAN (1979). In these films, which mirrored her offscreen relationship with Allen, she captured with fetching natural awkwardness the paradoxical personae of the modern urban American woman and helped set a fashion trend for thrown-together styles. She was also notable as Kay Corleone, the conscience-stricken wife in THE GODFATHER (1972) and its sequels; as the lost, promiscuous heroine of Richard Brooks's LOOKING FOR MR. GOODBAR (1977); she received an Oscar® nomination for her performance as the radical Louise Bryant in Warren Beatty's REDS (1981). The versatile Keaton (she chose her mother's maiden surname) published two photography books, Reservations (1980) and Still Life (1983), and tried her hand in film directing with an offbeat documentary about heaven, titled HEAVEN (1987). She directed a music video for singer Belinda Carlisle's "Heaven Is a Place on Earth," and in 1990 she began directing for TV, her early efforts including an episode of the cult serial "Twin Peaks." She turned in a deft comic performance as the driven career woman in BABY BOOM (1987). After Woody Allen's personal and professional split with Mia Farrow, Keaton took over what was to have been Farrow's role in MANHATTAN MURDER MYSTERY (1993), recapturing some of the chemistry of their earlier collaborations. Other notable (non-nominated) credits include PLAY IT AGAIN, SAM (1972), SLEEPER (1973), LOVE AND DEATH (1975), HARRY AND WALTER GO TO NEW YORK (1976), INTERIORS (1978), SHOOT THE MOON (1982), THE LITTLE DRUMMER GIRL and MRS.
