I can't see any movies being greenlit based on the performance of The Dark Knight, other than a third Nolan Batman flick. The out of the norm success of The Dark Knight has nothing to do with it being a comic book movie, but more with media coverage re: Ledger's death and glowing reviews that painfully point out it's "more than just
a comic book movie, it's something akin to the Godfather." The latter of which saddens me, because why can't
a comic book movie be that good? Regardless, it is these elements that have brought the Joe Blow movie going public to a film they wouldn't otherwise see.
