LOS ANGELES (AP) — Diane Keaton, the Oscar-winning star of “Annie Hall,” “The Godfather” films, and “Father of the Bride,” whose quirky, vibrant manner and depth made her one of the most singular actors of her generation, has died. She was 79.

According to People Magazine, she passed away in California surrounded by loved ones, with the news coming as a shock to fans globally. Keaton’s talent helped define iconic films that served as cultural touchstones, particularly her unforgettable portrayal of Annie Hall, which showcased her unique fashion sense and quirky humor.

Keaton's collaborations in the 1970s with filmmakers like Woody Allen established her as a leading actress. Even as her initial fame blossomed, she continued to assist newer generations of actors, particularly through her work with Nancy Meyers in films like “Something’s Gotta Give.”

Her repertoire included memorable roles such as a businesswoman who unexpectedly inherits an infant in “Baby Boom” and as the mother in “Father of the Bride.” Keaton was nominated for an Oscar a total of four times, clinching her first award for “Annie Hall.”

Born Diane Hall in January 1946 in Los Angeles to a homemaker and a civil engineer, she pursued acting in New York City after a brief stint in college. She adopted her mother's maiden name as her stage name and studied under Sanford Meisner, who greatly influenced her acting style.

Keaton's Broadway roots began with “Hair” and she received critical acclaim for her role in "Play It Again, Sam," which earned her a Tony nomination. Her breakthrough role in “The Godfather” solidified her status, and she returned for the sequel after much deliberation.

Diane Keaton leaves a profound legacy, defined by her ability to portray both comedic and dramatic roles with an authenticity that resonated with audiences. In her own words upon winning the Oscar in 1978, 'This is something,' and indeed, her career has left an indelible mark on the film industry.
