Real love is strange and changeable… but also somehow constant.

Heath Ledger's performance in The Dark Knight quite simply changed the game. He raised the bar not just for actors in superhero films, but young actors everywhere; for me. His performance was dark, anarchic, dizzying, free, and totally, thrillingly, dangerous.

I am desperate to do a comedy now.

In 'Thor,' that was my own hair. I grew it out. But I have naturally curly, blonde hair, so I'll never look like that. By the time I got to 'The Avengers,' I had come off two other films, which required me to have it very short. So I dyed it again and it was long enough to use a part of my hairline.

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.

The book [Night manager] is amazing. It is amazing to act in any book adaptation, because a book gives you so many secrets and details that don't necessarily get shot in an adaptation. They give you a cushion underneath everything. The detail in the character, the detail in the tone.

The thing about running is, if I run in the morning before work, I feel like I'm ahead of the day. Whatever work I've done in terms of preparation or research or thinking about the scene or the character, it all kind of crystallizes in that moment in the morning. And sometimes I have the best ideas then.
