Al Pacino's biggest regret was never marrying Diane Keaton, according to the Daily Mail.
The two actors played a married couple in Francis Ford Coppola's Godfather trilogy and had an on-and-off affair from 1971 to 1987.
“I know he will forever regret he didn’t make his move when he had the chance,”
a source told the Daily Mail.
“Looking back, Al admits the love of his life was Diane who he’s always called, ‘an amazing woman,’”the source added.
Al Pacino may have wished things went differently with his co-star, now that Diane Keaton has passed away at age 79.
