It seems like Tom Hanks has been everywhere recently promoting his new movie 'Larry Crowne.' And now, he's even taken to interrupting other star's interviews to promote the new flick.

On the 'Late Show' Thursday night, Hanks crashed a segment with co-star Julia Roberts while she played a game with David Letterman. A hilarious round of trivia similar to 'The Newlywed Game' followed.

Roberts seemed to enjoy herself, but she wondered how any of this was supposed to help 'Larry Crowne.' "Is any of this really going to get people to go see our movie?" she laughed.

"Nobody does this show to get people to see their movie," Hanks replied.
