22-year-old Australian actor Liam Hemsworth, who starred in 2010’s The Last Song (and began dating Miley Cyrus afterward), caught the eye of American directors even before his older brother Chris did. In fact, Chris’s biggest credit to date, the title role in last summer’s superhero blockbuster Thor, almost went to his little brother! Thor director Kenneth Branagh initially shortened his list of potential leads to four actors, including Liam (and excluding Chris)—but in the end, Chris won the hammer and helmet of the Viking lead role. He couldn’t have done it without the help of his younger brother though, who gave him tips based on his own experience in the screen tests for the role. “We’re competitive,” Chris told The Hollywood Reporter. “But in the best way.” There’ll be plenty of Liam to come though, with his role as Gale Hawthorne in the upcoming film The Hunger Games.
