John Simm wants to play Hamlet.

A lot: "I've asked him about the play he's rehearsing, of course, and he's told me, of course, that it's "a hell of a challenge", and that he was "intrigued" by the script, and the fact that it's "like a split-screen on stage", and that he's playing two characters, a detective (again) and a violent, alcoholic neighbour. And then he announces, casually, that he "wasn't particularly looking to get back on stage again", but was wanting to do Hamlet. Whoa! And he hasn't done any Shakespeare before? "No." And wouldn't it feel a bit like following in the footsteps of David Tennant? "I didn't really think about that." And he's only ever seen one Hamlet? "Yes, at drama school." And doesn't it, um, imply quite a lot of confidence?"
