Why It Would Rock: Back in 2009, Battleship director Peter Berg was actually attached to helm a remake of the acclaimed sci-fi book Dune, and according to people "in the know" – meaning people who probably don't actually know anything – Pattinson was set to star. The role requires someone who can play brave, noble, aristocratic and fierce all while looking young. He would have been perfect for it!
Why It (Probably) Won't Happen: Dune is one of those cursed projects. Many directors have tried and failed to bring the book to life with little success. And yes, I'm including the way-too-long 1984 David Lynch movie. It's just too big of a project to ever make well.
