Since he broke out in a huge way playing Doctor Who, it's fair to say that Matt Smith's had an undeniably interesting career. He's gone out of his way to work with interesting directors and has taken parts that have stretched him in all sorts of different directions (just check out his mohawk in this summer's movie release Caught Stealing).
He seems to have an excellent radar for parts that will make for interesting performances, which makes his latest TV project very interesting.
