Chris Hemsworth isn't a demigod, he just plays one in a massively popular superhero franchise. And while the physics of Asgard might make it so a long red cape and flowing blond hair are the best things to bring into battle, in reality Hemsworth winds up looking exactly like you think you would in a giant battle scene: with that giant red cape flopped over his head.I didn't really mean to talk to Hemsworth about his costume when I interviewed him about Thor: The Dark World a few weeks ago in London, but when I walked into the room he was sitting there with his shoes off, wearing thin black socks instead of Thor's big leather boots. That led to talking about leather pants, and then how to handle Thor's hammer (and the fantastic visual gag that he improvised), and then of course to the cape, which seems like an awful pain in the neck to drag behind you whether you're fighting off Dark Elves or not.I also couldn't help but ask him about the status of The Avengers: Age of Ultron , which of course he couldn't tell me anything about-- but it was interesting to hear that he's actuallynot to be able to answer anybody's questions, especially since he hadn't read the script. Withopening in theaters this weekend , it won't be untilin 2015 that we see Hemsworth back on-screen as Thor. That gives him plenty of time to practice his cape-wrangling.
