As a teenager, Smith dreamed of playing soccer professionally (he's shown, above right, in a 2010 episode of Doctor Who). Smith was picked for the youth teams of Nottingham Forest and Leicester City, but a back injury forced him out of the game. Instead, Smith decided to pursue acting and was cast in the National Theatre's acclaimed production of Alan Bennett's History Boys. In 2006, Smith appeared in Burn/Chatroom/Citizenship, a trio of plays aimed at young people. One costar of the future Doctor? Future Spider-Man Andrew Garfield. ''I remember at the read-through going, 'Whoa, this kid's good.''' Smith later told EW. ''And he is.''
