Interview with Zach Galifianakis & Robert Downey Jr. (Due Date)

Only director Todd Phillips would think of teaming Robert Downey Jr. and the hysterically funny Zach Galifianakis together in a movie. The actors take the lead in the new comedy Due Date, about a high-strung father-to-be (Downey Jr.) who is forced to hitch a ride with an aspiring actor (Galifianakis) in order to make it to his child's birth on time.

Tribute's Bonnie Laufer caught up with the duo in Los Angeles to talk road trips, comedic chemistry, and even had them improv a scene on demand!
