Annie (Kristen Bell) plays a dumpy-town college professor who's totally content living there with boyfriend Charlie (Dax Shepard). But when her boss lines up a job interview for her in Los Angeles, the opportunity seems too good to pass up. The only problem: Charlie is in the witness-protection program and isn't supposed to leave. Determined not to hold his girlfriend back, Charlie decides to risk it all and go to L.A. with her. But Annie's jealous and revenge-minded ex has other plans for the couple. Shepard, who also wrote and co-directs, has great onscreen chemistry with Bell (he should — they're a real-life item too), and the supporting cast (including Bradley Cooper rocking some white-boy dreads) is solid. But Hit & Run isn't a very smart movie, even if the ride is occasionally enjoyable.
