Trivia

She is not related to Michael Keaton, as her birth name is Diane Hall. She changed her last name to her mother's maiden name as a result, because a Diane Hall was already being registered in the Actors Guild. Coincidentally, Michael Keaton had a similar problem with his natural name when entering the Guild, as his birth name is Michael Douglas (not related to Kirk Douglas's son, Michael Douglas). It is a misconception that he named himself after Diane Keaton. When he needed an alternative surname, he landed on the letter K and thought that Keaton sounded inoffensive enough.

Where did you learn to use your face so well? I think you ran across every emotion in the book, then threw the book away and made up some of your own".
