The audition said it all. He came in the room and by the time he left I said, ‘He made me raise my game. I want to work with him.’ He’s incredibly supportive and grounding, as he is as Watson. He’s a brilliant foil and we laugh a lot; a helluva lot, and we work very hard, and then we laugh very hard, and then we work hard and then we laugh hard. It’s genuinely good fun. I adore him. He’s somebody who’s got a very secure understanding of life. He’s a homebody and has a beautiful family and he’s just a very centered, very amusing, brilliant actor to play off.
