3. JJ Feild
JJ Feild was born in Colorado, USA, but his parents moved to London when he was a baby, so he still qualifies for this list. Another actor proficient in both film and television, JJ Feild may be best known for either his role as Henry Tilney in the 2007 adaption of Jane Austen's Northanger Abbey (cast alongside Felicity Jones and Carey Mulligan), or for his 2011 role in the Marvel film Captain America: The First Avenger. However, he's had an abundance of other roles as well, including playing a young version of Michael Caine's character in Last Orders... and you know how suave someone must be in order to pull off a young Michael Caine. He's also portrayed a young man caught in a murderous love triangle in an adaption of Death On the Nile. Overall, I think he could tackle an incarnation of the Doctor very similar to that of David Tennant. Also, doesn't he quite look like Tom Hiddleston (who would also be a great Doctor)?
