After Diane died in October 2025, Warren wrote an emotional tribute to his late friend in an essay published by The Free Press. In it, he briefly touched on the end of their romance, writing that “only God and Freud might be able to figure out” why they didn’t last as lovers.
“This beautiful yokel went on to become an award-winning actress and sophisticated fashion icon,” Woody added about Diane.
Al Pacino
Diane moved on with her The Godfather co-star Al Pacino. They had an on-again, off-again relationship until they wrapped filming The Godfather Part III. It’s unclear what exactly led to their split, but according to several reports, Diane gave Al an ultimatum: get married or break up.
According to Daily Mail, a friend of Al’s told the outlet that Diane was the love of his life, and that he always called her an “amazing woman” even after their split.
“I know he will forever regret he didn’t make his move when he had the chance,” the source told the outlet. “For years, after he and Diane split, Al used to say, ‘If it’s meant to be, it’s never too late for a do-over.’ But sadly, immediately it is.’
Warren Beatty
