We're only a few weeks away from 'Due Date,' the comedic re-teaming of 'Hangover' director Todd Phillips, and the very bearded, very funny Zach Galifianakis. In 'Due Date,' Robert Downey Jr. stars as a soon-to-father who is racing on a cross-country trip to be there for the birth of his child. The only thing that could get in his way is his travel companion, the oddball Ethan -- played by Zach G.

The movie doesn't open until Friday, November 5, but fans can get a unique performance from Galifianakis and Phillips, when the two join Moviefone for an episode of Unscripted.

On Wednesday, Oct. 27, Galifianakis and Phillips will take turns interviewing each other using questions supplied by you. This is your chance to learn anything and everything from the big-screen funnymen -- you might find out how Phillips was able to control someone like Zach G. on the set, you might see them argue over what is the funniest movie ever made, or you could even see them attempt to portray Sherlock Holmes better than RDJ.

Really, you can ask anything you want, just make sure to submit your question before Tuesday, Oct. 26, by 12PM EST in the comments below, and to include your name and location.

Come back here on Monday, November 1 to watch the interview and to see if your question made the cut!
