Kristen Bell And Dax Shepard Are Relieved They Actually Have Chemistry

If you're an actor and you're in a relationship with another actor, you better hope that the chemistry translates to the screen. Otherwise, things could get a little embarrassing.

Kristen Bell and Dax Shepard, real-fiances, definitely felt the pressure for their new movie, "Hit & Run," which casts them as two lovers on the lam. When MTV News sat down with the couple, they said they understood the challenge.

"It was kind of high-risk," Shepard said. "Because had we not had chemistry, that would have been rough for everyone."

But even if they hadn't clicked on screen, Bell reminded him that it wouldn't have been the first time. "I think plenty of people have watched movies with people without chemistry," she said.

"But when they are dating, it's rough," Shepard said. "When they are engaged, it's rougher."

Since things went so well the first time around, Shepard said that he wants to get a franchise of movies going with the two of them as stars.

"I'd like to be Kurt Russell and Goldie Hawn and do four or five of these suckers together," Shepard said. "In fact, we should redo the boat movie, 'Overboard.' I'd be Jack, right?"

"I would have a shoe closet," Bell said. "This is perfect."

"Yes, look for 'Overboard' next fall in a marina near you," Shepard said.
