Recently, Hollywood's AARP set has churned out a bumper crop of movies about baby boomers getting along just fine. Last year's The Best Exotic Marigold Hotel saw 78-year-old Maggie Smith, 79-year-old Dame Judi Dench, and a slew of others mixing it up in a retirement home in India. Dustin Hoffman, 75, made his directorial debut with Quartet-also set in a home. The Expendables 2 rounded up 66-year-old Sly Stallone, 73-year-old Chuck Norris, and 65-year-old Arnold Schwarzenegger for a blow-'em-up flick good for grandpa and the kids alike. Go further back, you'll find plenty: The Bucket List, Something's Gotta Give, Space Cowboys, RED, Divine Secrets of the Ya-Ya Sisterhood, etc.
