The news is not encouraging as director Kenneth Branagh is unlikely to return. According to Deadline, Kenneth still may be involved in the production. Related news, the Marvel Studios has not been willing to give an explanation.
Kenneth never claimed that he had given all the best in the first film. He claimed to be surprised by some directors who save something for a second or third film.
"I put it all on film if I thought it helped the movie become the best," said Kenneth. "You can think about the idea for the film two or three later, if you get a chance to work again."
According to the plan, "Thor 2" will be released around July 2013.
