I'm really surprised nobody has posted this since Superman is supposedly everyone's favorite American hero, ok, not mine either but another movie is being developed. Superman: Man of Steel was green lighted a budget of $250 million, thanks to Warner Bros couple of months ago. With Zack Snyder (300, Watchmen, Dawn of the Dead) behind the camera, and script written by David S. Goyer.
There were many rumors that it was another reboot, I kinda liked the last remake but Superman was never my favorite comic book either, and its kinda hard to top the one and only original Superman (film wise), Christopher Reeve but this character is forever cursed.
Anyway, a French site, Filmsactu.com caught up with Zack Snyder during his European tour to promote his animate film "Legend of the Guardians", and asked him about Superman, and what the movie will be about. Here's his response translated from French...
"As I already explained, the film will be focused on the early days of Superman. It will not have links with the other films. This will not be a remake. Again, even though I can't talk about the story, I can assure you that this new Superman will not be based on any particular comic book." This puts to bed any speculation that this new movie would be based on either Mark Waid's "Superman: Birthright" or John Byrne's "Man of Steel" miniseries.
