From director, Todd Phillips, who brought you such hits as ,Road Trip, Old School, and last years' critically acclaimed, The Hangover, Due Date is guaranteed to bring laughs. The film tells of Peter (Robert Downey Jr.) and Ethan (Zach Galifianakis), both of whom venture from Atlanta to Los Angeles by car; Peter strives to appear home in time for his wife to give birth to their first child, hence the title of the film, and Ethan is in hopes of becoming an actor, out in Hollywood. The actors work very well with one another as well as the script. The short tempered Peter is a successful architect who has very little patience. Ethan is none other than the typical character which Zach Galifianakis is famous for playing. In fact, throughout the movie, the character of Ethan is very reminiscent of Alan in The Hangover. With that said, Galifianakis is also able to defy his boundaries as an actor, in this film, and at times showcases a far more serious, very in tune with himself, actor.
