British-born Asa Butterfield began his acting career when he was eight years old, playing the role of Andrew in the 2006 TV movie After Thomas. He would make a bigger splash the next year, with a role in the indie comedy Son of Rambow, and again the next year, in the Holocaust drama The Boy in the Striped Pyjamas. Butterfield then took on the role of Mordred in the TV series Merlin, before joining the cast of the 2010 family film Nanny McPhee and the Big Bang. While his role in the latter did offer the charismatic youngster a respectable amount of exposure to the tween set, it was Butterfield's next big role -- as the eponomous orphan in Martin Scorsese's Oscar-winning film Hugo -- that truly cemented his reputation as a rising star. On the heels of that resounding success, Butterfield made Hollywood headlines when it was announced that he would next take the lead in Enders Game, a big-budget adaptation of Orson Scott Card's celebrated sci-fi novel.
