The first poster for Todd Phillips' new comedy Due Date has gone online.  The film stars Robert Downey Jr. as an expectant father who's forced to hitch a ride with an aspiring actor (Galifianakis).  Mayhem ensues.  I dug the trailer for the film, but it's interesting that this poster borrows from the poster for Phillips previous film, The Hangover, in that you have another handsome actor looking tired and physically beaten.  They've also replaced the cute baby with a cute dog.  You also have Galifianakis (obviously).

Hit the jump to check out the poster and the official synopsis.  Due Date opens on November 5th.

Here's the synopsis for Due Date:

Peter Highman is an expectant first-time father whose wife's due date is a mere five days away. As Peter hurries to catch a flight home from Atlanta to be at her side for the birth, his best intentions go completely awry when a chance encounter with aspiring actor Ethan Tremblay forces Peter to hitch a ride with Ethan--on what turns out to be a cross-country road trip that will ultimately destroy several cars, numerous friendships and Peter's last nerve.
