There's a plethora of wonderful documentaries. I made a point of not looking at anyone else's portrayal of Henry because I think it would have been too confusing - so I've got a lot of films to look forward to.

It's always hard but the reality is, especially in my case, that every time I go to work I have to do it so it's become part of the job. It's an extra challenge but it's also quite often another extra tool that you have to really think consciously about getting into the character. So while it does require more work, it's maybe even an advantage to a degree because it forces you to switch, to consciously have to jump into and out of the character.

By the time I finished comedy, I was really burnt out of it. I had had enough. I don't really have a strong desire to prove myself in that area, or to go back to it in any great way.

It's always been my hope, as an actor, to reveal only what is relevant about myself to the work.

The thing I love about working with first-time directors is that it's always quite shocking how little difference there is between them and directors who've been directing all their lives.

The more I love the character, the harder it is to get it wrong. I have to get to a point that I can speak for them.

When you're shooting a film, you really don't get to be a dad, and you don't really get to be a husband. You don't really exist at all. But I do drag my family with me on location whenever I can.
