He was apparently in something in 2010 with Aaron Johnson and kissed him.
He's in a bunch of small British shows. Very talented. I'm watching Magpie Murders, which is a two-in-one story where most of the actors play multiple roles. His two roles are Conleth Hill's jaded boy toy and considerate-but-kind-of-daft assistant to the private investigator. And you believe him in both roles, even when they're emphatically juxtaposed in contrasting scenes.
