Dax Shepard and Kristen Bell are famously engaged (remember when he got her a sloth for her birthday and she flipped out?), and later this summer they’re co-starring in a new action comedy lcalled Hit and Run. Now Funny or Die has a behind the scenes video from the production that reveals that the two had to call in the big guns – namely Tom Arnold – to bring their real-life chemistry to the screen. Things get hilariously awkward when Tom gets a bit TOO involved, but it’s good to see that everyone in the film has a good sense of humor. Check out the video below!

Synopsis: From the producer of Wedding Crashers – written and co-directed by and starring comic talent Dax Shepard (NBC’s “Parenthood”) HIT AND RUN is the story of Charlie Bronson (Shepard), a nice guy with a questionable past who risks everything when he busts out of the witness protection program to deliver his fiancé (Kristen Bell) to Los Angeles to seize a once-in-a-lifetime opportunity. Their road trip grows awkwardly complicated, when they are chased by the feds (led by Tom Arnold) … and increasingly dangerous, when Charlie’s former pals, a band of gangsters (led by Bradley Cooper), enter the fray.
