"Don’t you think my life is confusing enough? And listen, if John Simm could hear you, you would not live another hour. He came up to me after the press [junket] for the End of Time where he’d been saying ‘I think now that David has left as The Doctor, I would have to leave as The Master’ but then he pulled me aside and said ‘I didn’t mean that! And look at me, I’m fit! I’m OK!’ So Benedict has to wait in line probably. But how confusing would it be? All four cheekbones at once! I tell you, I stood between [Matt Smith and Benedict] in a photograph once. It’s a really good way to look extra ugly."
