Tom Hiddleston told Yahoo! Movies that during a fight scene, he instructed Chris Hemsworth to really hit him: "[Chris] really went for it and he's just pummeling me in the chest and elbowing me in the face and Joss [Whedon, the director] came back after that take and went, 'We got it. It's great.'" In "Marvel's The Avengers," Hiddleston reprises the role of Loki -- first seen in last year's "Thor" -- the adopted brother of the god of thunder with an apocalyptic case of sibling rivalry.
