All Peter Highman (played by Robert Downey Jr.) wants to do is be there as his new baby is being born in the upcoming comedy Due Date. But while on the road he's forced to hitch a ride with wannabe actor Ethan Tremblay (played by Zach Galifianakis, of course) whose silly antics don't bode well with Highman's high-strung, by-the-books personality. Sorry, folks, this looks lame. How did Robert Downey Jr. get mixed up with this mess? Due Date, which reunites Downey with his The Soloist co-star Jamie Foxx, hits theaters November 5.
