Kenneth Branagh has reportedly opted not to return to direct Thor 2 for Marvel and Disney despite the commercial success of the first Thor.

Deadline claims Branagh's split with the studios was "mutual and amicable," and that he'll probably involved with the sequel in some creative capacity. This obviously means the director's chair is now open, so expect the rumor mill to start churning out names soon.

Marvel has scheduled Thor 2 for a July 26, 2013 release and that Chris Hemsworth, who is also playing Thor in the now-filming Avengers movie, is set to reprise the role again for Thor 2. Iron Man 3 is also slated for a summer 2013 bow.

At least he'll still be on as creative.

EDIT:
Heh...I didn't realize it was in the other Thor forum.
