12. Arthur Darvill
Arthur Darvill is best know for playing Rory on Doctor Who, one of the Doctor's long-suffering, frequently dying companions. Husband of the lovely Amy Pond, father to River, he's an undisputed fan favorite. But to the surprise of many fans, Darvill is also an accomplished musician. During his teens and early twenties, he was in an indie rock band called Edmund, in which he performed leading vocals as well as keyboard and guitar. Earlier this year, he made his Broadway debut in Once: the Musical, where he has taken over the lead role of Guy. His voice is passionate and raw, and provides a pleasant surprise for all those who see the show.
