Last week, we showed you the first in a series of behind-the-scenes featurettes for DreamWorks Pictures' Need for Speed, which showed footage of star Aaron Paul in his driving training sessions. The studio has released the second featurette, offering a look at the amount of work that must go into these cars, to make them ready for the production. Director Scott Waugh is shown watching these cars perform on the race track, and we also see a team of mechanics tweak these muscle cars to make them as fast as possible. This adaptation of the popular Electronic Arts video game franchise hits theaters nationwide March 7.
