To me, it's all about inspiration. What gets me creatively excited is a challenge.

I've always been a night person. There's a sense of virtue attached to getting up in the morning and doing things and starting the day, and I always felt bad for not being that person. But as I've gotten a bit older, now I'm completely okay with it. That's just who I am.

I started acting when I was 9. I did smaller parts here and there as a kid, and then as I grew older I started resisting it, because I didn't like the idea of being, at the time, number four of the Skarsgård actors. So in high school I majored in science and was like, "Maybe I'll do something rebellious and become a doctor."

I come from a family of pacifists, so it's not like I was going to join the war. Sweden is not like the States or England where you might get sent to Afghanistan next month.

It's not about being proud of Sweden; it's just a sense of belonging. Even if you've lived in a place for a long time, those first formative years are going to be a part of you forever, and it's something you can't replace.

In movies we tend make things black and white: you're either this, or you're that.

It's funny: it takes a while to really get your character. It's impossible to do it on the first day. That's the same way in films; if you start shooting a film, maybe a couple weeks in, you're like, "Ah! Now I think I really get him."
