In this comedy about fatherhood, Robert Downey Jr. (Iron Man, Tropic Thunder) plays Peter Highman, an expectant first-time father whose wife's due date is a mere five days away. As Peter hurries to catch a flight home from Atlanta to be at her side for the birth, his best intentions go completely awry when a chance encounter with aspiring actor Ethan Tremblay (The Hangover's Zach Galifianakis) forces Peter to hitch a ride with the slacker - on what turns out to be a cross-country road trip that will ultimately destroy several cars, numerous friendships and Peter's last nerve. Oscar® winners Jamie Foxx (Ray) and Alan Arkin (Little Miss Sunshine) add to the chaotic fun as Downey's friend and father, respectively. Produced and directed by comedy powerhouse Todd Phillips (in his follow-up to the $400+ million worldwide box-office smash The Hangover), this road trip comedy represents the ultimate buddy comedy...without the buddies!
