Metalocalypse director Jon Schnepp went well beyond his $98,000 Kickstarter goal earlier this year to produce a movie about the abandoned Tim Burton/Nicolas Cage film Superman Lives. Now, a new teaser trailer for the doc, The Death of Superman Lives, proves that at least the movie about the movie is really happening next summer, and will include interviews with Grant Morrison, Mark Waid, and perhaps even Cage himself. You can see the full video update about the upcoming documentary, after the jump.
