Do the Due with Zach and RDJ in these clips from Due Date

It must have seemed obvious for director Todd Phillips to pair his breakout star of THE HANGOVER with another hot Hollywood commodity for another raunchy R-rated comedy.

We’ll find out how the Zach Galifianakis/Robert Downey Jr. duo does delivering the laughs when DUE DATE hits theaters next weekend, but for now here’s another sample to see if you’re feeling the funny.

The movie has Downey as a dad-to-be, joined by Galifianakis (plus a canine and canned man) on a cross-country trek to be with his wife at the birth of his first child. Hilarity ensues, or at least abuse and general awkwardness.
