Chris Hemsworth

Miley Cyrus' future brother-in-law Chris Hemsworth donned a seriously heavy costume while shooting a scene on the set of "Thor: The Dark World" in Surrey, England, on Tuesday. Since it's a sequel, the Aussie actor already has plenty of experience with the wardrobe ... and knows the importance of it. "It sells the picture," he told MTV News in 2010, "and you can't feel like anything but that character when you put that thing on." (9/11/2012)
