The first trailer for the action romantic comedy Hit and Run has gone online.  Dax Shepard stars as an ex-getaway driver who exits the Witness Protection program to drive his pretty girlfriend to Los Angeles so that she can land her dream job.  The authorities and his former gang (led by Bradley Cooper) get wind of his reappearance and set out to chase him down.  Shepard wrote and co-directed the film with David Palmer, and it actually looks like a pretty fun comedy.  Cooper appears to be having a blast as a flashy gang member, and real-life couple Shepard and Bell have some excellent chemistry.  Moreover, Tom Arnold is in fine form as a U.S. Marshal who’s trying to protect Shepard’s character.

Hit the jump to watch the trailer.  The film also stars Kristin Chenoweth, Beau Bridges, David Koechner, Joy Bryant (Parenthood), and Ryan Hansen (Party Down).  Hit and Run hits theaters on August 24th.
