Paterson Joseph has reportedly been cast as the Eleventh Doctor on Doctor Who, although the BBC hasn't made an official announcement yet. If true, he'll be the first Black actor to play the Doctor.

He previously appeared in the 2005 episodes "Bad Wolf" and "The Parting of the Ways" as Rodrick, much like Colin Baker had previously played a different character in a serial before becoming the Sixth Doctor. He also played Benjamin in several episodes of Jekyll, a show created by new Who showrunner Steven Moffat, and may be best known in some circles as the Marquis de Carabas in the 1996 television adaptation of Neil Gaiman's Neverwhere.

Here's a backstage video diary Joseph made while in rehearsals for the play Saint Joan. I think he shows the qualities to make a good Doctor.
