Keaton's first film appearance was in "Lovers and Other Stranger" in 1970. Her many early TV credits include appearances on "Mannix," "The F.B.I.," "Night Gallery" and "Love, American Style."

Keaton starred as Al Pacino's Girlfriend Kay in "The Godfather" (1972), and repeated the role in the crime saga's two sequels.

Keaton had appeared on Broadway in the musical "Hair," and in Woody Allen's "Play It Again, Sam." She recreated her role in the 1972 film, beginning a long cinematic string of movies with the writer-director.

Woody Allen's romantic comedy "Annie Hall" (1977) was a cinema landmark for countless reasons, including its wry, absurdist script and Allen's long-suffering character, while perfectly capturing the sensibilities of New York and L.A. But it would not have worked without Keaton's scintillating, ditzy and touching performance as Annie.

While Keaton won raves for her comic turn in "Annie Hall," she also earned critical plaudits for her dramatic performance in "Looking for Mr. Goodbar" (here with Richard Gere), as a young woman self-destructively hitting the singles' bars.

Keaton also appeared in Woody Allen's Bergman-esque drama, "Interior" (1978), with Kristin Griffith and Mary Beth Hurt.

Keaton's received a second Academy Award nomination for her performance as journalist and Marxist writer Louise Bryant, in Warren Beatty's epic drama of early socialism in the U.S. and Europe, "Reds" (1981).

Keaton starred opposite Albert Finney in the drama of a family torn by infidelity, "Shoot the Moon" (1982).

A turn-of-the-century period drama based on a true story, Keaton starred as a prison warden's wife who abandons her husband and children to help a convict and his brother escape. "Mrs. Soffel" (1984) was directed by Gilliam Armstrong ("My Brilliant Career"). Keaton earned a Golden Globe nomination for Best Actress - Drama.

Keaton starred with Jessica Lange and Sissy Spacek in the film version of the stage play "Crimes of the Heart" (1986). Also in the cast: Sam Shepard, with whom Keaton later starred in "Baby Boom."

In "Baby Boom" (1987), Keaton played a career woman who life and values are thrown into turmoil as she becomes guardian to the child of a deceased relative.

Though Mia Farrow replaced Keaton as the lead female in Woody Allen's films in the 1980s, Keaton returned to sing in a cameo in the 1987 comedy-drama "Radio Days."

After the very public disintegration of Woody Allen's relationship with Farrow, Keaton returned to the director's "Manhattan Murder Mystery" (1993). In the comical thriller about a couple of amateur sleuths investigating the mysterious disappearance of a neighbor, the two played as if Annie Hall and Alvy Singer were an "old married couple," with as much exuberance as their previous screen counterparts.

Keaton and Steve Martin were parents experiencing the pain and agony of wedding planners and other nuptial horror tales, in the 1991 comedy "Father of the Bride."

In "Marvin's Room" (1996), Keaton starred as the estranged sister of Meryl Streep (and aunt of Leonardo DiCaprio, pictured) in a performance that earned her a third Oscar nomination.

Nancy Meyers' "Something's Gotta Give" (2003) gave Keaton the chance to be the object of affection for two generations of leading men, including Keanu Reeves.
