Chris Hemsworth, star of this weekend’s Thor, ranked No. 1 in our study of this summer’s biggest biceps — and we weren’t even basing our calculation on Hemsworth at his buffest. As director Kenneth Branagh told us, he had to ask his lead to tone down the musculature. So how did Hemsworth feel about his whole too big problem? We asked the Aussie at a screening of Thor hosted by the Cinema Society and Acura, and he told us, “I was pretty disgusted with myself for a bit. I was a bit concerned. I was sort of thick all over and that costume doesn’t have much give in it. It started to cut off circulation and my hands would go numb. I had to start running and eating less to get my body down.” On a separate note, we asked him to weigh in on why so many superhero roles are going to non-American actors: “There must be an international appeal to us,” he said. “Also, I think we probably come cheaper than Americans.” For more quotes from celebrities, click through our slideshow.
