BEVERLY HILLS, CA - JULY 09: Actor Billy Crystal arrives at The Academy of Motion Pictures Arts and Science's 'The Last 70mm Film Festival' Screening Of 'It's A Mad, Mad, Mad, Mad World' at AMPAS Samuel Goldwyn Theater on July 9, 2012 in Beverly Hills, California.
Crystal starred in the hit films "City Slickers" and "When Harry Met Sally" and has hosted the Academy Awards nine times. He turns 65 next year and has made a career out of turning his life into comedy: "City Slickers" was a story of mid-life crisis and "Parental Guidance" is based on Crystal's experiences with his own grandchildren.
The actor is also working on a book that will be part memoir with jokes about getting older.
Friday's "Parental Guidance" screening is one of the highlights of the AARP's national convention being held in New Orleans.
