Keaton began her career on stage and made her screen debut in 1970. Her first major film role was as Kay Adams-Corleone in The Godfather (1972), a role she reprised in The Godfather Part II (1974) and The Godfather Part III (1990). But the films that helped shape her early career were those with director and co-star Woody Allen, beginning with Play It Again, Sam in 1972. Her next two films with Allen, Sleeper (1973) and Love and Death (1975), established her as a comic actor. Her fourth, Annie Hall (1977), won her the Academy Award for Best Actress.
