Robert Downey Jr. and Zach Galifianakis star in this winning comedy as a very unlikely duo on the road to Los Angeles. Full of the kind of humor that made 'Planes, Trains and Automobiles' a hit, Peter (Downey) and Ethan (Galifianakis) must get to L.A. by deadline--the birth of Peter's child by C-section--while dealing with the elements and each other on the road.
