PictureLux on the red carpet report: "Due Date" premiere.

Robert Downey Jr and Zach Galifianakis walked the red carpet in LA, for the world premiere of their new comedy "Due Date" held at Grauman's Chinese Theater in Los Angeles on Thursday, October 28, 2010.

Downey Jr. made his way down the press line with his lovely wife Susan, while Galifianakis toted his adorable French Bulldog costar.

Other stars of the film, like Jamie Foxx, Michelle Monaghan and Juliette Lewis, also made appearances that night, joined by producer/director Todd Phillips. Additionally, comedian Ken Jeong made a guest appearance bringing along some stand-up routine for the walk down the carpet.

As for style watch, Michelle Monaghan wore her dark hair in loose curls for the premiere and were perfect for the bright red Versace dress. Complementing the red mini were nude Christian Louboutin pigalles heels.

About the film, Director Todd Phillips re-teams with his break-out "Hangover" star Zach Galifianakis for the road movie concerning a soon-to-be father (Robert Downey Jr.) and his cross-country trip to make it back in time for his baby's birth ... with the only roadblock being the dubious passenger (Galifianakis) who's along for the ride.
