Two new clips from the mother of all road trip movies: The Guilt Trip, starring Seth Rogen (Pineapple Express) and Barbra Streisand (The Prince of Tides) hit the web, Collider reported.

Directed by Anne Fletcher (The Proposal), the Dan Fogelman (Crazy, Stupid, Love) script centers on an L.A.-based inventor (Rogen) who takes his recently-widowed mother (Streisand) on the road with him for a business trip in which he hopes to sell his latest idea and help rekindle his mother’s love life.

The Guilt Trip opens December 19th.
