Benedict Cumberhatch: Currently in "Sherlock"
Jonathan Rhys Meyers: Coming this fall as the lead in "Dracula" on NBC
Clark Gregg: I'm going to call "The Avengers" current, although it has left theaters. "Agents of S.H.I.E.L.D." is coming to ABC this fall.
Jonathan Pryce- best known as Governor Swann in "Pirates of the Caribbean" franchise. But you should see him singing and hoofing (dancing) in "De-Lovely". His French General Delatombe in "The Brothers Grimm" was comic perfection.
Rupert Graves: Currently in "Sherlock" and probably more British television that is never shown in the US but "V for Vendetta" and "The Last King" are when I started looking for him.
Only part of my "B" list but the trend from my "A" list seems to continue. Only one is American. I think even if I listed them all the trend would hold true. I wish I could explain it.
