The legendary Barbra Streisand plays Seth Rogen's mom in the upcoming film 'The Guilt Trip,' and the pairing looks absolutely hilarious. Check out the first trailer for the road trip comedy, which hits theaters this Christmas.

A nice Jewish boy is worried about his lonely, doting Jewish mother, so he invites her on a road trip across the country to help her break out of her shell a little in the new film 'The Guilt Trip.' Seth Rogen plays son to Barbra Streisand, and if you think that sounds a little off, you need to check out this trailer because the casting just couldn't be more perfect.

Written by Dan Fogelman (who also scripted the similarly heartwarming comedy 'Crazy, Stupid, Love') and directed by Anne Fletcher ('The Proposal,' '27 Dresses'), 'The Guilt Trip' co-stars Yvonne Strahovski, Adam Scott, Colin Hanks and Danny Pudi.

We've got the first official trailer, courtesy of Yahoo Movies, and while it does feature some stereotypical "moms are old and wacky" humor, the chemistry between Streisand and Rogen is really selling us on the film, which hits theaters just in time for Christmas (or Hanukkah, whichever you prefer). If you're curious about the song in the trailer, that's the Scissor Sisters' "Take Your Mama."
