As WB big-cheese Jeff Robinov explained to the Wall-Street Journal:
"'Superman' didn't quite work as a film in the way that we wanted it to. It didn't position the character the way he needed to be positioned. Had 'Superman' worked in 2006, we would have had a movie for Christmas of this year or 2009. But now the plan is just to reintroduce Superman."
Personally, I was a fan of Bryan Singer's Superman Returns and was anticipating his sequel (i.e. the oft-titled Superman: The Man of Steel!) Ahhh well! Nothing anyone can do about that.
I'm first and foremost a fan of the character. So let's just hope that the studio lines up the right talent behind the camera with the right direction for Superman.
But a new concern seems to have arisen from the same article:
"Like the recent Batman sequel -- which has become the highest-grossing film of the year thus far -- Mr. Robinov wants his next pack of superhero movies to be bathed in the same brooding tone as 'The Dark Knight.' Creatively, he sees exploring the evil side to characters as the key to unlocking some of Warner Bros.' DC properties. 'We're going to try to go dark to the extent that the characters allow it,' he says. That goes for the company's Superman franchise as well."
I wouldn't worry (if at all, to be honest) towards the "dark" remarks from Robinov. They're coming from a real high at the moment with The Dark Knight kicking so much butt at the box-office. He's basically just talking out loud throwing out ideas.
Nothing more, nothing less.
And prepare yourself for months of 100% Grade-A B.S., folks. At the moment, there is no director nor screenwriter(s) currently working on the new Superman revival film. Nor is there a storyline or approach that everyone at WB has agreed upon.
It basically boils down to this, boys and girls. The studio knows exactly what they don't want, and they're working from there.
Regardless of what ultimately goes down, Superman will return to the silver screen again... eventually.
