Asa Maxwell Thornton Farr Butterfield (born 1 April 1997 in Islington) is an English actor probably best known for portraying Bruno in The Boy in the Striped Pyjamas, the eponymous hero of Hugo, and Ender Wiggin in the film adaptation of Ender's Game.He began acting at age 8 after he was spotted by a casting director at a local drama club, and soon did the Made-for-TV Movie After Thomas. From there he had a supporting role in Son of Rambow before doing an episode of Ashes to Ashes in 2008. In the same year he won the recurring role of the infamous Mordred in The BBC's Merlin — a role not dissimilar to his successful performance in Rambow, possibly why he was cast. Released around the same time was the film adaptation of The Boy in the Striped Pyjamas, in which he starred.Asa was still attending regular school like any other boy and would put his career on temporary hold from the Autumn of 2008, when he began secondary school, with a supporting role in The Wolfman followed by the lead in the sequel to Nanny McPhee released in 2010. In these films he played alongside people like Sir Anthony Hopkins and Emma Thompson, and his own real stardom began. Following this he got the lead in Martin Scorsese's adaptation Hugo, leading the renowned cast comprising Sir Ben Kingsley, Sacha Baron Cohen, and Chloe Grace Moretz.Returning in yet another book adaptation, Ender's Game was filmed during his final year of high school, suggesting that he now considers his acting career a priority over his education. Asa plays the titular Ender Wiggin in one of the most anticipated films of 2013, again heading up the All-Star Cast, including Sci Fi veteran Harrison Ford.
