Sounds like Kenneth Branagh is at least considering (some people in the movie business also calls this "being on the short list") Josh Hartnett to play the God of Mischief Thor's big tall and ugly brother Loki.
IESB.net had this to say "Loki isn't a very nice guy. He's quite treachorous actually and fancies himself the God of Mischief. He is repeatedly trying to get rid of Thor and seize the throne of Asgard for himself. One thing led to another and he ended up being the God of Evil. What will his role in Marvel's live action adaptation? Probably something similiar, we know he's the main baddie.
Who does Brannagh want to bring this evil character to life? Try Josh Hartnett. IESB sources say Hartnett has met with Brannagh as well and he is currently on a very short list to play the villain in the film."
Sure ok Josh Hartnett, why not. Josh turned in a great performance in Black Hawk Down and oh, he hasnt done anything note worthy since then. But Josh is a talented actor who I think could pull this role off with out giving it the stupid jester like feel.
IESB did mention that this is not set in concrete so if the paparazi snap pictures of Josh jogging and then ask him quickly about Thor and he mentions "You bet your ass", dont take that seriously.
