Diane Keaton Died of Pneumonia, Death Certificate Says

Diane Keaton, the Oscar-winning actress known for her roles in “Annie Hall,” “The Godfather,” “Reds” and other films, died of primary bacterial pneumonia, according to a death certificate that was released Thursday.

Keaton died Saturday at the age of 79 at Saint John’s Health Center in Santa Monica, Calif. according to the death certificate. No underlying causes of death were listed on the certificate, which said that no autopsy had been performed.

Over the course of her career Keaton performed in more than 100 roles in television shows, in films and on Broadway. She was admired for both her dramatic power and her comedic timing. She won the Academy Award for best actress for her performance in “Annie Hall” in 1978, and was nominated three other times in that category, for roles in “Reds” in 1982, “Marvin’s Room” in 1997 and “Something’s Gotta Give” in 2004.

Her final acting role was in “Summer Camp,” a comedy released in 2024 about three old friends reuniting at their childhood sleep-away camp.

Tributes to Keaton and her work have streamed in since her death.

Woody Allen, who directed her in “Annie Hall” and several other films, wrote that he “made movies for an audience of one, Diane Keaton.” Francis Ford Coppola, who directed her in all three of the “Godfather” films, called her “creativity personified.” And the writer and director Nancy Meyers, who directed her in “Something’s Gotta Give” and other films, mourned her as a “brilliant actress who time and again laid herself bare to tell our stories.”
