We're fascinated by things that scare us, and one of the things that scares us is violence. Violence exists. It's a real part of our lives. We are obsessed with what we're scared of, but it certainly doesn't define us.

I did one sci-fi movie. I did 'Gattaca.' I liked 'Gattaca' because that was always the kind of science fiction I really dug, the non-action oriented sci-fi.

I've very rarely worked with somebody that had such a clear idea of what Alejandro Amenábar wanted to do and what he wanted to achieve. The guy is incredibly prepared. He was clearly making a movie for himself and his own dream. I just tried to be a part of that dream. It's a rare opportunity.

It was a really strange experience. It was very creative for Alejandro Amenábar. It was almost like it was the most I ever felt like I was helping someone paint. They had a very clear idea of what they wanted it to look like, sound like, be like. So, there was no operating outside the box. The only way to help him was to try to really be a part of his imagination and try to make it happen. He's a super kind and loving person. So, you wanted to help him. It just was none of my normal ways of helping a director work at all. So, it was a unique experience for me that way.

Years ago I was going to play Chet Baker in another movie and I really felt drawn to that character and the script is good and I met with Robert and we seemed simpatico and we developed. But I had a real passion for that role and that brought me deep into that film 'cause I got the sense that Robert Budreau was going to really let me be creative inside this part.

I did this movie, Predestination, and it's one of my favorite movies I've ever made, because sci-fi really lets you talk about ideas in a way that's not pretentious.

It's interesting to work with Emma [Watson] so quickly after Harry Potter. When we shot this movie, it wasn't that long after Harry Potter was finished, and it's knowing that's a big transition in her life. She's a very talented young woman.
