I find that what doubt does, or fear, is it makes you come up with as many ideas as you possibly can. And on film that works 'cause you're then handing over that fear to the director, who has to make sense of all those options!

I'm trying to buy a house and set some sense of roots because otherwise you're constantly chasing one job after another, and you look back and you've had all these very extraordinary experiences with extraordinary people, but there's not a line of continuity to it.

On so many levels, acting in film and TV is so much the sum of its parts, and somewhere in there, there's an alchemical thing that makes something happen or not - that makes something connect or not.
