Hunger Games star Liam Hemsworth stopped by Peter Travers' office at Rolling Stone headquarters to chat about going on a mall tour in advance of the movie's release, his role as a love interest for Jennifer Lawrence's Katniss Everdeen, sparring with older brother Chris "Thor" Hemsworth, and getting his ass kicked by 10-year-olds when playing Call of Duty. "They make fun of you over the earpiece," he says. "I'm okay, I've played a lot and should be a lot better, but these little 10 year olds are just really talented!"
