Robert Downey Jr. & Zach Galifianakis' "Due Date" Trailer

We've been hearing about Due Date for a while now. Director Todd Phillips follows up The Hangover with this gem of a comedy. Robert Downey Jr., Zach Galifianakis, road trip, 'nuff said. Check out the trailer... I don't like it at all, but have hope the movie will be funny.
