I blogged about Kenneth Branagh being in talks to direct the Thor movie a few weeks ago and now it may be confirmed. He must be pretty confident at least if he's given up directorial duties on a new West End rendition of Hamlet starring Jude Law.
http://www.imdb.com/news/ni0584393/ I'm really interested to see how this plays out. As I mentioned before, Thor needs a thorough grounding in reality in order to be considered part of the same universe as his more scientific Avengers buddies and I think Branagh with his Shakespearean background could be the one to instill him with some.
