I find that, when I'm working, if I start the day with a run - outside, not in a gym, but just me out there in the elements, with only my own legs to propel me forward... It's something to do with just being in the world and getting out of my own head.

It’s always about, somehow, finding a part of myself that is relevant, and then turning the volume up on that particular part. So, I am all of the characters I've ever played, and I am none of them at the same time.

I even feel grateful for the failures.

I'm sure favorite moments in movies are things that just happen accidentally when the camera is there. You have to do all the homework to get yourself into the period, the costumes, the style, the voice, the hairdo or whatever it is, but once you've done all that work, you have to kind of let it go and just be there. If you're always thinking about it, it just looks a bit over-thought.

Vietnam is absolutely breathtaking. I've never been to that part of the world before and it is an area of such natural beauty.

Some of the greatest actors have turned superheroes into a serious business: Michael Keaton and Jack Nicholson in Batman; Ian McKellen and Patrick Stewart, the first venerable knights of the X-Men, who have now passed the baton to Michael Fassbender and James McAvoy.

I think a healthy connection with the natural world actually makes us more human.
