Later this week Diane Keaton will receive the American Film Institute's Life Achievement Award. The Oscar-winning actress says she has her mom, dad, and Woody Allen to thank for all that she's accomplished. She credits her parents for instilling a strong work ethic and "Annie Hall" for launching her career. Keaton's career has spanned five decades and more than 80 films. She will receive the AFI award at a Hollywood Gala on Thursday.
