'Due Date' directed by Todd Phillips (Hangover) stars Robert Downey Jr and Zach Galifianakis as two unlikely companions thrown together on a road trip, that turns out to be as life-changing as it is outrageous.  Downey   plays Peter Highman, an expectant first time father whose wife's (Michelle Monaghan) due date is only days       away.  As he hurries to catch a flight home to Los Angeles from Atlanta, his chance encounter with aspiring actor and disaster-magnet Ethan Tremblay (Galifianakis) leads to the two of them being tossed off the plane and placed on a no-fly list. And that's where the fun begins.  'Due Date' isn't a laugh a minute, but ultimately it is a funny, and touching film.  Also in the cast are Jamie Fox, as Downey's best friend, Juliet Lewis, who has the whole 'druggie' thing down pat and a really adorable French bull dog.  The dog's masturbating scene is worth the price of admission alone.  Opens in theaters Friday, November 5, 2010.
