An actor has to be very, very careful, as one of the most wonderful props - and actors love props - is a cigarette. There's so much to do with it: you can bring it up to your face, play with the smoke. It's just the greatest - ever since I was 16 and in acting school in England, I've been playing around with cigarettes.

It's not exactly an interview that's going on [in documentary]. I guess we do ask Edward Snowden some questions and we're recording him answering them and so on like that.

There is a wealth of knowledge to be understood from others' work, don't get me wrong, and when I do stumble upon others' work, it's not lost on me.

As an actor, you live a little bit of a cloistered life. It's a lonely life. You oddly, strangely find yourself all alone, quite often, with a lot of time to think.

You can't really gauge the difficulties of television. There's difficulties and joys that happen with an amazing, great team, when one is working. Television can be a very frustrating job for almost anybody working in television, because you're shooting episodically, and you don't know one scene from the next, and maybe they change around.
