Diane Keaton Repeatedly Reminisces About Gibson Kiss

Diane Keaton treasures the moment she locked lips with Mel Gibson in 1984 movie Mrs Soffel, insisting the screen kiss is among the highlights of her life.

The Annie Hall star played Gibson's older love interest in the movie and Keaton admits she was so taken by the actor, she will never forget the romantic moment.

She tells People magazine, "Could he have been more beautiful? I was like 39, and he was... a baby!

"I got in the car to go home, and I kept reinventing that kiss. Over and over".

The love scene is one of many memories Keaton recalled for her new autobiography, Then Again.
