What is Thor?

So Kenneth Branagh's going to direct some comic book film, something about a hero named Thor, and people think it will work because it's a very costume-heavy period-film-like comic. OK. Sure. I am a little surprised that he's taking on this new kind of challenge, just because he seemed very uninterested in large-scale Hollywood films a few years ago when he was in Harry Potter and the Chamber of Secrets (and just a delight in that as a ridiculously vain professor, by the way). There was a lot of speculation at that time as to whether he would like to direct one of the HP films, and he expressed disinterest in the special effects, etc. Of course, a stand-alone is different from a huge franchise like HP, so I wish him luck with it. And I await what I always think of as his trademark shot, the camera on a round track circling a small group of characters. Occasionally makes me dizzy.
