Scott here. I think The Guilt Trip has a chance to be very funny. The story of a mother and son hitting the road together on a cross-country trip has major potential.  I like the chemistry between Seth Rogen and Barbara Streisand.  Who wouldn't want Barbara Streisand to play their mom in a movie? "If my penis grew an eyeball I wouldn't tell you" has to be the most random line in movie history.  Click below for the trailer.
