Yeah there is the Christopher Nolan(Memento, Insomnia) Batman, Darren Arronofsky/Frank Miller Batman, Batman Beyond film project, Jack Nicholson film idea, Catwoman(which actually might be filmed pretty soon), etc. No telling 'which' Batman film will be made...but Im pretty sure WB wants to have it out by 2005...a good decade since the last somewhat watchable Batman flick.
The Catwoman film just seems odd, as how could ya have a Catwoman film with no Batman?
Sadly, the biggest of all the bad boys, Superman vs. Batman was so close to being green lit...but then the director passed on it for another film. Currently Red Dragon/Rush Hour's director Bret Ratner is tapped for Superman.
...but Marvel has got DC beat so far, with a continuous string of huge box office comic iflms with no end in sight. Now if only comic book sales themselves werent still so bad.
