A second full trailer has been released for the documentary The Death of Superman Lives: What Happened? This one goes a "little deeper into the misconceptions that the public had of this production, and the effects that had on everyone involved." It focuses on Tim Burton’s unique vision for Superman, and includes some really cool never-before-seen footage like Nicholas Cage in some costume tests, some concept art, and a lot more stuff that I'm sure you'll find interesting. It's actually really kind of cool to get some deep insight into what Burton was really planning. The doc is being directed by Jon Schnepp, and he's almost finished with it. I can't wait to see more!
