But is it too late?
I've been carousing the SHH.com boards and discovered that DC just put together and flung out their (hack-job) line up of movies, but they're all very pushed back.
The soonest will be Jonah Hex in 2010. I'm sorry, but they can't expect money off a character no one knows/cares about.
That's why the got Batman & Superman... in 2011

Then we got Flash in 2012, which is being written but no say on who. It looks like Roy Thomas is attached to both that and the movie about Green Arrow.
Green Arrow is interesting because (as I have noted before) it won't do well. But for a movie that's un-marketable, it's impressive what they're doing for it. Being written by Kevin Smith & Neal Adams, the story is going to involve Black Canary, of course, and is supposedly "going to be filled with everything that makes Green Arrow awesome, minus the crap that makes him not so awesome."
What that means, I don't know.
