Right now, Marvel Studios and its newly hired director Kenneth Branagh are wrestling with the difficulty of casting Thor. Sure, there’s a big push to cast Josh Hartnett either in the winged helmet and/or as nemesis Loki, which is ironic since Warner Bros once upon a time threw an amazing amount of money at him to play Superman but he refused. But my sources say there’s an equally powerful lobby to cast an unknown. I’ve heard that, besides Hartnett, the following actors are being tested: Charlie Hunnam (the British co-star of the F/X series Sons Of Anarchy); Tom Hiddleston (award-winning British actor and RADA graduate who played Winston Churchill’s son in HBO’s The Gathering Storm), Alexandar Skarsgard (Stellan’s son who has appeared in the HBO Iraq War miniseries Generation Kill and vampire drama True Blood, and who’s definitely visually right for the role), Liam Hemsworth (offered a significant role in The Expendables after Sly Stallone saw his tape), and Joel Kinnaman (some Swedish-American dude). Meanwhile, I’m told Natalie Portman is in the lead for the female lead. (So I guess Marvel wants a wooden performance…)
