STARRING Robert Downey Jr., Zach Galifianakis, Michelle Monaghan
WRITTEN BY Alan R. Cohen, Alan Freedland (screenplay), Adam Sztykiel
DIRECTED BY Todd Phillips
Downey plays Peter, a tightly wound businessman forced by bizarre circumstances to drive from Atlanta to L.A. with an eccentric and hugely irritating wannabe actor named Ethan (Galifianakis). What appears at first to be a simple odd-couple road comedy develops deeper strains as Peter races to make it home for the birth of his first child and Ethan grieves for his dead father. ''It could have been so two- dimensional,'' says Downey. ''It's not that oh-my-God-we're-doing-a-dramedy horses---. But I think it's a step forward for Todd as a filmmaker as far as the emotional depth and complexity.''
