Now, Peter had no intentions of trekking across the country with the bulldog-carrying, Lilith Fair-shirt sporting Ethan, but after both of them end up on a "no-fly" list, there's no other alternative. They experience the ins and outs of America's strangest locales from rest stops to Western Union with all kinds of nuttiness transpiring around each bend. Galifianakis imbues Ethan with a natural sensitivity that makes him even funnier and ultimately more tangible, while Phillips once again architects masterful madness for the characters. They're the ultimate comedy team...

Due Date star Zach Galifianakis and director Todd Phillips sat down with ARTISTdirect.com editor and Dolor author Rick Florino for an exclusive interview about what makes Due Date so hilarious, the best road trip songs, their playlists that Lilith Fair shirt and some of Zach's "favorite" head shots.
