While Warner Bros. chose to sit out of Comic-Con, the talk around town in San Diego was all about the DCEU and Crisis On Infinite Earths, and now I have learned that J.J. Abrams will be taking on both Superman and Green Lantern.
My understanding is that a big reason why J.J. Abrams recently signed that mega-deal with Warner Bros. is that he wants to tackle the DC movie characters, and that he is going to do movies for Superman and Green Lantern first
It's also known that WB passed on Mission Impossible director Chris McQuarrie and Henry Cavill's Superman pitch for a Man of Steel 2 and Green Lantern, which according to what I have been told is because of Abrams' own plans.
I don't have specifics about what Abrams is going to do with Superman and Green Lantern, but the question of Henry Cavill did come up. It seems to be that Abrams is leaning toward casting a younger actor as Superman to go along with Robert Pattinson as the new Batman.
