I just watched the teaser trailer for the first time. I got goosebumps. I've never been a Superman fan, but I've always wanted them to release something that would do it justice. Hopefully this totally new reboot from Nolan (as producer) will do what he did for Batman, but with Superman. From the trailer music sounds like Zimmer is composing too, although I could be mistaken.
