Acting was always there, it's true. But for a long time, in my teenage years, I wasn't sure about it - not because I didn't like it, but I didn't want people to think I hadn't earned it.

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."

I worked with Lady Gaga for a day on a video shoot. It was crazy; we had a lot of fun. I had a great time.

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."

TV is a very sensitive thing. If you're not happy with what you're doing, I don't think you should do it because you will do it for awhile.

Personally I don't believe in bad people. I think there's always a reason for people acting badly.
