Many speculated that the movie was based on Keaton and Allen’s relationship. She told The New York Times in 1977, “It’s not true, but there are elements of truth in it.”

Keaton would collaborate with Allen again in 1978’s Interiors, 1979’s Manhattan and 1993’s Manhattan Murder Mystery. She also defended Allen in the wake of sexual abuse allegations from his stepdaughter Dylan Farrow. “I love him,” she told The Guardian in 2014.

Keaton’s other film roles included 1977’s Looking for Mr. Goodbar, 1981’s Reds, 1982’s Shoot the Moon and 1984’s The Little Drummer Girl. She worked with Meyers for the first time on 1987’s Baby Boom. They would reunite three more times: in 1991’s Father of the Bride, 1995’s Father of the Bride Part II and 2003’s Something’s Gotta Give, which garnered another Oscar nom for Keaton. Asked which of these projects she loved the most, Keaton told Vulture in 2020, “Honestly, you can think it’s sappy, but I love the Father of the Bride movies. They were so touching.”

Keaton starred with Goldie Hawn and Bette Midler in 1996’s The First Wives Club, about three women whose husbands had left them for younger women. The comedy famously ended with all three singing Lesley Gore’s “You Don’t Own Me.” Keaton told The Hollywood Reporterin 2023 that she was “always kind of anxious and a little worried” while filming it because Hawn and Midler were “really amazing actresses.”

Later roles for Keaton included The Family Stone, Because I Said So, Finding Dory, Book Club (and its sequel) and Poms. She made a rare TV appearance with a starring role in HBO’s 2016 miniseries The Young Pope. Keaton also worked as a director, helming the 1987 documentary Heaven, 2000’s Hanging Up and an episode of Twin Peaks.

In 2021 Keaton starred in Justin Bieber’s music video “Ghost.” She also was a prolific Instagram user, posting updates on her life, reflections on her career and friendships and praising those she loved.

Looking back on her career, Keaton told PEOPLE in 2019, “I don’t know anything, and I haven’t learned. Getting older hasn’t made me wiser. Without acting I would have been a misfit.”

Keaton never married. “Today I was thinking, I’m the only one in my generation of actresses who has been a single woman all her life,” she explained to PEOPLE in 2019. “I’m really glad I didn’t get married. I’m an oddball. I remember in high school, this guy came up to me and said, ‘One day you’re going to make a good wife.’ And I thought, ‘I don’t want to be a wife. No.’”

She was romantically linked to Allen, Pacino and Warren Beatty over the years. “Talent is so damn attractive,” she noted to PEOPLE.

Keaton had two children, daughter Dexter and son Duke, whom she adopted in 1996 and 2001, respectively. “Motherhood was not an urge I couldn’t resist, it was more like a thought I’d been thinking for a very long time. So I plunged in,” she told Ladies’ Home Journal in 2008.

Keaton is survived by her children.

The cause of death for legendary actress Diane Keaton was revealed on Wednesday, just days after her untimely passing at the age of 79.

The family of the Annie Hall star told People magazine that Keaton officially died on October 11 from pneumonia.

“The Keaton family are very grateful for the extraordinary messages of love and support they have received these past few days on behalf of their beloved Diane, who passed away from pneumonia on October 11,” they wrote in a statement.

“She loved her animals and she was steadfast in her support of the unhoused community, so any donations in her memory to a local food bank or an animal shelter would be a wonderful and much appreciated tribute to her,” the family added.

As Breitbart News reported at the time of her death, Keaton rose to stardom despite dropping out of high school and changing her name from Diane Hall to Diane Keaton:

Keaton was born in Los Angeles, California, in 1946 and received an Oscar for her role in the film Annie Hall, directed by Woody Allen. This was neither the first nor the last time she was to work with Allen, with whom she was romantically involved. The two met when she attended an open audition for Allen’s Play it Again Sam on Broadway, and she got the role. Other films directed by Allen starring Diane Keaton include Manhattan and Radio Days.

Keaton’s given name was Diane Hall. She dropped out of high school and moved to New York to try her hand at Broadway. When she was cast in the musical Hair, Keaton was the only actor to refuse to strip for the finale.

Keaton won a single Oscar for her groundbreaking role in Woody Allen’s Annie Hall and was later nominated for her turn in Reds, Marvin’s R00m, and Something’s Gotta Give. Though she never married, Keaton is survived by her adopted daughter and son, Dexter and Duke.
