How we were going to get there, what the choices were going to be, who was going to be in it – all of those things I knew would have to be figured out, but it was all based on a foundation of this indescribable, guttural passion for something that could be. It’s a similar feeling that I have with Star Wars. I feel like I can identify a hunger for what I would want to see again and that is an incredibly exciting place to begin a project. The movies, the worlds could not be more different but that feeling that there’s something amazing here is the thing that they share.”
Whaaaaaaaaaaaat he didn't even mention a mystery box!
