Diane Keaton (born Diane Hall on January 5, 1946) is an Academy Award-winning American film actress, director and producer. Keaton began her career on stage, and made her screen debut in 1970. Her first major film role was as Kay Adams in The Godfather (1972), but the films that shaped her early career were those with director and co-star Woody Allen, beginning with Play It Again, Sam (1972). Her next two films for Allen, Sleeper (1973) and Love and Death (1975), established her as a comic actress. Her fourth, Annie Hall (1977), won her the Academy Award for Best Actress. Keaton has claimed that she is "tailor-made for comedy". Keaton took on different kinds of roles to avoid becoming typecast as her Annie Hall persona. She became an accomplished dramatic actress, starting in Looking for Mr. Goodbar (1977) and received Academy Award nominations for Reds (1981) and Marvin's Room (1996). Some of her popular later films include Father of the Bride (1991), The First Wives Club (1996), and Something's Gotta Give (2003). Keaton's films have earned a cumulative gross of over USD 1.1 billion in North America. In addition to acting, she is also a photographer, real estate developer, and occasional singer.Keaton's most famous romance was with director Woody Allen for most of the 1970s. Keaton and Allen first met during Keaton's audition for the Broadway production of Play It Again, Sam, but they did not know each other personally until having dinner after a late night rehearsal. Allen claims that Keaton's sense of humor attracted him to her. They briefly lived together during the Broadway run of Play It Again, Sam, but their relationship became less formal by the time the film version was produced in 1972. They went on to produce eight films together between 1971 to 1993. After Keaton's working relationship with Woody Allen diminished in 1979, she began dating her Reds co-star Warren Beatty. Keaton's involvement with Beatty also made her a regular subject of tabloid magazines and media at the time, a role to which she was unaccustomed. (As a result of her avoidance of the spotlight, Vanity Fair described her in 1985 as "the most reclusive star since Garbo".) Beatty and Keaton separated shortly after completing Reds. Their separation was believed to have been caused by the strain of making the film, a troubled production with numerous financial and scheduling problems. Keaton still maintains contact with both Allen and Beatty, but describes Allen as one of her closest friends. Keaton also had a relationship with Al Pacino her co-star in the Godfather Trilogy. The on-again, off-again relationship ended following the filming of the Godfather Part III. Keaton has said in reference to the relationship that "Al was simply the most entertaining man... To me, that's, that is the most beautiful face. I think Warren was gorgeous, very pretty, but Al's face is like whoah. Killer, killer face."
Diane Keaton is mother of two children: a girl named Dexter (adopted 1996) and a boy named Duke (adopted 2001).
She has co-starred with Stephen Collins in two movies; The First Wives Club (1996) and Because I Said So (2007). She is not related to actor Michael Keaton. Like Diane, Michael used an alternative surname to remove confusion with another well-known actor. In fact, Michael had decided to select "Keaton" after reading an article about Diane in 1979.
