I'm very aware that when one is acting in the theater, you do become kind of animal about it. And you're reliant on instincts rather than tact a lot of the time.
When I am asked about influences, I always say I bow down to Fred Astaire, because when you look at him dancing you never look at his extremities, do you? You look at his centre. What you never see is the hours of work that went into the routines, you just see the breathtaking spirit and freedom.
I approach every part I'm asked to do and decide to do from exactly the same angle: who is this person, what does he want, how does he attempt to get it, and what happens to him when he doesn't get it, or if he does?
Three children have become adults since a phone call with Jo Rowling, containing one small clue, persuaded me that there was more to Snape than an unchanging costume, and that even though only three of the books were out at that time, she held the entire massive but delicate narrative in the surest of hands.
Certainly as actors, and maybe as directors, you've got to hang on to something childlike. You've got to know what play is. I haven't worked with Mike Leigh, but I know him very well and there's something open in his eyes about what's in front of him. And the same is true of Alfonso in a Mexican, mad way. There's an enthusiastic response to something. Neil Jordan, the same, when he gets excited . You just want to know there's a human being in there.
