During the Marvel panel, Hemsworth spoke about the third "Thor" film, reported E! online.

"If we're going to make a third film we really have to push the envelope and experiment take it to another level so that is what this film was. Cut his hair, break his hammer, change his clothes, change the world. I think that's what you're going to see and be excited about," said the star.
