We live in a world of denial, and we don't know what the truth is anymore.

I'm getting so old - it's more uncomfortable to do those scenes now than when I was 20. I mean, I don't have a big problem with nudity on screen. But usually the days when you do those naked love scenes are the weirdest ones on set. Everyone is uncomfortable. You're like, 'Hi. How are you?' Then the next minute you're with an actress who you don't know and you're pretending to make love to her in front of all the crew. The acting challenge is pretending things are OK.

Awards were made in Hollywood, in whatever the time it was created. They're to promote each other's movies. You give me an award, I give you an award and people will believe that we are great movies and they'll go to see them. It's still the same.

When I see myself at 14 years old I can put my hands on my head and think: 'How could I have done that?' but at that time it had sense for me. You do the same when you're 20. And now, when you look at people who are 20 years old you ask yourself: 'Was I like that? Was I really like that?'

But I remember the moment when my father died. I wasn't a very committed Catholic beforehand, but when that happened it suddenly all felt so obvious: I now believe religion is our attempt to find an explanation, for us to feel more protected.

I'm a huge fan of the director, Alejandro González Iñárritu, and his work, and I knew he was going to be an amazing actor's director, based on the performances that I saw in his movies.

I don't think an actor needs to necessarily go through his things to do his job. I think it's way more important to imagine. And then, when you're imagining, your experiences, your images and your own personal things will show up, but you keep imagining. You don't get stuck in your own personal things, otherwise you are telling your story in every character, and that's not interesting for anybody.
