At the end of "Annie Hall," Woody Allen's character Alvy says love is "totally irrational, and crazy, and absurd," but "we keep goin' through it." So, too, did its star, Diane Keaton, who died at age 79 on Oct. 11, People and The New York Times reported.

The Oscar winner − who grew up in Los Angeles before getting her start on Broadway in "Hair" and transitioned to film with "Lovers and Other Strangers" before being cast in iconic films as wide-ranging as "Annie Hall," "The Godfather" and "Something's Gotta Give" − never married, but had several high-profile Hollywood relationships.

Keaton started dating Woody Allen in the late 1960s, when she starred in his Broadway show, "Play it Again, Sam." The perennially shy actress said working with him on his comedic films helped her relax and feel more comfortable.

Though their relationship didn't last, she remained his supporter for decades after he faced sexual abuse allegations. (In 2018, she tweeted, "Woody Allen is my friend and I continue to believe him.")

They costarred in eight films, but it was "Annie Hall" that won Keaton an Academy Award for best actress.
