The Radio Times has added Luke Treadaway to the list of actors rumoured to be up for playing the 13th Doctor. Google that and Sacha Dhawan also comes up as a possible contender.
Ignoring Dhawan's earlier link with the Whoniverse (he played Waris Hussein, one of the first directors to work on Doctor Who in 1963, in "An Adventure in Space and Time") I'm amused that if it's Treadaway he, like Pearl Mackie, will have come to the show having been in the stage production of "The Curious Case of the Dog in the Nightime" and, if it's Dhawan, he was a History Boy, like Matt Smith before him.
All hail the N.T. (National Theatre)
