His most acclaimed roles include: Stephen Hawking in the BBC drama Hawking (2004); William Pitt in the historical film Amazing Grace (2006); the protagonist Stephen Ezard in the miniseries thriller The Last Enemy (2008); Paul Marshall in Atonement (2007); Bernard in Small Island (2009); and Sherlock Holmes in the modern BBC adaptation series Sherlock (2010).

Yes, I know I'm overlooking a lot of contenders, but this man is the "actor of the year." In a short time, he has made himself into a huge sensation (probably by accident). From his suave looks, to his baritone British accent; so few actors have such a specific sex appeal. For a long time he's been a professional actor, working in various roles, and keeping fresh every time. My personal favorite is his modern characterization of Arthur Conan Doyle's "Sherlock" from BBC. But picking one role is like picking a single flower from a bucay, they all blossom so brilliantly.
