Breaking Bad star Aaron Paul has a fall-back career as a movie stunt driver if he ever tires of acting, thanks to the training he signed up for ahead of new movie Need For Speed.

The actor chose to perform his own stunts in the all-action film and so director Scott Waugh, a former stuntman, hired the best drivers to teach him how to look professional behind the wheel of a speeding car.

Waugh explains, "If his acting career doesn't work out he'll be a great stuntman."

Paul also had to bulk up for the role of a vengeful racing driver.

Waugh adds, "I wanted him to have that racer's body, so we got him a trainer and a dietician. I think he gained about 30 pounds of muscle."
