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 a generation, has died. She was 79.

People Magazine reported Saturday that she died in California with loved ones, citing a family spokesperson. No other details were immediately available, and representatives for Keaton did not immediately respond to inquiries from The Associated Press.

The unexpected news was met with shock around the world. Keaton was the kind of actor who helped make films iconic and timeless, from her “La-dee-da, la-dee-da” phrasing as Annie Hall, bedecked in that necktie, bowler hat, vest and khakis, to her heartbreaking turn as Kay Adams, the woman unfortunate enough to join the Corleone family.

Her star-making performances in the 1970s, many of which were in Woody Allen films, were not a flash in the pan, as she continued to charm new generations for decades, thanks in part to a longstanding collaboration with filmmaker Nancy Meyers.

She played a businessperson who unexpectedly inherits an infant in “Baby Boom,” the mother of the bride in the beloved remake of “Father of the Bride,” a newly single woman in “First Wives Club,” and a divorced playwright who gets involved with Jack Nicholson’s music executive in “Something’s Gotta Give.”

Keaton won her first Oscar for “Annie Hall” and would go on to be nominated three more times, for “Reds,” “Marvin’s Room” and “Something’s Gotta Give.”

In her very Keaton way, upon accepting her Oscar in 1978 she laughed and said, “This is something.”

Keaton was born Diane Hall in January 1946 in Los Angeles, though her family was not part of the film industry she would find herself in. Her mother was a homemaker and photographer, and her father was in real estate and civil engineering.

Keaton was drawn to theater and singing while in school in Santa Ana, California, and she dropped out of college after a year to pursue an acting career in Manhattan.

She studied under Sanford Meisner in New York, who helped her explore the complex human behavior that defined her performances throughout her career.

Keaton made her film debut in the 1970 romantic comedy “Lovers and Other Strangers,” but her big breakthrough would come a few years later when she was cast in Francis Ford Coppola’s “The Godfather,” a film that would become one of the most beloved of all time.

The 1970s were marked by her collaborations in romantic and comedic roles, including films like “Sleeper,” “Love and Death,” and “Interiors.” Allen and the late Marshall Brickman gave Keaton one of her most iconic roles in “Annie Hall,” the infectious woman from Chippewa Falls whom Allen’s Alvy Singer cannot get over.

The film is considered one of the great romantic comedies of all time, with Keaton’s eccentric, self-deprecating Annie at its heart.
