According to Variety, Robert Downey Jr. will star with Zach Galifianakis in Due Date the comedy that Todd Phillips will direct for Warner Bros. this fall.
Downey will play an expectant father who finds himself on a road trip with a mismatched partner, as he races to get there before the birth of his first child.
Galifianakis, who starred for Phillips in The Hangover, plays his road trip mate in a comedy that Phillips calls "a buddy comedy without the buddies."
The script was written by Alan R. Cohen and Alan Freedland, revised by Adam Sztykiel. Shooting will begin in September, in Atlanta, New Mexico and Los Angeles.
