The problem with conversion is that it tends to be a little pop-up-book. For "Drive Angry," we've got these great cars in the film — a '69 Charger, a '71 Chevelle — and the lines of those cars, to try and post-convert, you'd never get all of the depth and the beauty of those machines. Shooting in 3-D, you get all the angles of the cars and you feel like you're in it with Nic Cage behind the wheel.
