This British charmer was Lorenzo in the acclaimed Al Pacino production of The Merchant of Venice before charming us as Tristan Thorn in the adaptation of Neil Gaiman’s fantastical Stardust, opposite Claire Danes and Michelle Pfeiffer. He came on strong this past season on Boardwalk Empire as Nucky’s body man Owen, who ended up stealing into the bed (and heart) of his employer’s wife, Margaret. But it didn’t end well for the go-to hitman, as he ended up mailed in a box, and not the coffin kind.
