Branagh is, for better or for worse, officially out. Who would you like to see take his place.
Possible Choices (Though I Don't Think They Will Actually Be Chosen):
director has invented the modern day superhero genre. He makes movies with depth, humor, action, and astounding visuals. It would be hard to find a better choice.
Renny Harlin Die Hard 2
and 12 Round
s director Harlin is not used to fantasy, but he definitely knows how to do action. He has an annoying tendency towards shaky-cam, but he generally makes entertaining films with everything wanted from an action movie. And he usually works with a smaller budget, and his visions could be improved with more money.
Martin Campbell Green Lantern
was a flawed movie, yes, but it also proved Campbell is skillful with super-hero, fantasy-esque movies. And the more comic Thor would be a better choice for the light attitude that some were offended to see used on Hal Jordan.
X-Men Origins: Wolverine managed to make a good story that fit continuity with the other XMEN films and left room for other movies (such as Gambit). And Hood won tons of praise for indie pictures.
