Diane Keaton’s cause of death revealed as pneumonia

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 released Thursday.

Keaton died Saturday at the age of 79 at Saint John’s Health Center in Santa Monica, California, according to the death certificate. No underlying cause of death was listed on the certificate, which indicated that no autopsy was performed.

Over the course of his career, Keaton played more than 100 roles in television shows, films and on Broadway. She was admired for both her dramatic power and 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.

His last acting role was in “Summer Camp,” a comedy released in 2024 about three old friends reunited at their childhood sleepaway camp.

Tributes to Keaton and his work have been pouring in since his death.

Woody Allen, who directed her in “Annie Hall” and several other films, wrote that he “made films for an audience of one person, Diane Keaton.” Francis Ford Coppola, who directed her in all three “The Godfather” films, called her “creativity personified.” And 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 time again laid herself bare to tell our stories.”
