When I was auditioning for Divergent, I was kind of in the dumps. I wasn't really happy with acting, and I didn't know if I wanted to do it anymore. I went on a bunch of auditions and nothing worked out. Then they said, "Hey, you got a callback for this thing, Divergent." Because I was in such a weird place in my life, I didn't look up what it was about, didn't look up the director, didn't look up that Shai Woodley was a part of it. I read the script, obviously, but I closed myself off from anything else.

I met Harrison Ford when I was at Comic Con. I didn't know what to say. He was standing behind these two bodyguards - I think he was going up next for Ender's Game - and I had just come off the panel. I saw him sitting over there and I couldn't believe it, so I just walked over to him. He looked right at me and said, "Are you Michael Madsen's son? You look a lot like your dad. You've got a great look, man. I think you're going to have a good future." I just couldn't believe he said that, and then he walked right onto the panel.

Having my parents be divorced, you're forced to realize, "Sooner or later I'm going to be on my own and have to figure it out." I have so many brothers that are younger than me, so I have to have that mindset of, "Okay, what am I going to do now?" I have to show them what growing up is - it's not me living at dad's house until I'm 25.

I kind of hid acting from my dad because I knew what he thought about acting at the time. His advice was "Don't do it," basically.

I knew nothing about hockey when I came to Chicago and then became the biggest fan - went to every playoff game.

When I was 16 was just thinking about the future and - it sounds so stupid - but what my goal was going to be in life. I guess I was thinking about girls too. No girls liked me. That was bothering me. I was thinking about my height - I had a growth spurt right before high school and then that's when sports coaches started coming up to me, but that's when I had this artistic turn.
