Newly minted DC Comics Chief Creative Officer Geoff Johns just dropped the bomb on twitter.

Back from an amazing trip to Green Lantern town a.k.a. New Orleans!! Ryan IS Hal. And Mark Strong is going to be a brilliant Sinestro.

We’ve known for some time that Ryan Reynolds has been cast as Hal Jordan in the forthcoming Green Lantern movie, and other casting notes have surfaced for secondary character over the last few weeks. Now with shooting mere weeks away in the Big Easy, the big question for who would play Sinestro is answered: British actor Mark Strong .
In this film the villain will be Hector Hammond, played by Peter Sarsgaard. Sinestro will play a supporting role in the story, as Hal’s mentor as he eases into his role as Earth’s Green Lantern. DC and Warner Bros want GL to be a major franchise not unlike Batman or Iron Man, so they’re going to save Sinestro as a villain for a later movie.
And now that I typed that, I can see Green Lantern going exactly in the direction of the Iron Man movie. Not a bad thing.
