Tom Hanks And Julia Roberts Do The Late Show

Tom and Julia headed to The Late Show to promote their new flick, Larry Crowne, Tuesday night.

The movie is Hanks' pet project -- he directed it and co-wrote it with My Big Fat Greek Wedding star Nia Vardalos (Tom and his wife Rita produced Wedding after seeing it as a play.)

Hanks got the crowd outside laughing with his cute antics, then had the Late Show audience rolling with his dead-on impression of director (and friend) Ron Howard. Said Tom: "I'm going to get a Tweet from Ron about this after." Love it!
