From dfw.com:

Is it true that you got the role of Reid even though you really weren’t interested in being an actor or in doing TV?
“Yeah, I really sort of fell into it. I’m so lucky. I studied directing. And I had a directing agent who, long story short, said, ‘Hey, why don’t you go in a try out for this TV show pilot. There’s a character on there that’s sort of interesting.’ And I went in and got it. It was sort of a miracle, I guess, because I didn’t have any major interest in acting. But I since have fallen madly in love with it. It’s been great.”

That’s a great story. But actors who have worked much harder for their breakthrough roles, as well as those who are still waiting for their big breaks, must resent how easily it happened for you.
“Yeah, I’ve experienced that a little bit. But I’m of the belief that, if you love acting, then you can act anywhere. You can do local plays. You can do something. It’s maybe only people who are more interested in getting notoriety that really resent me. And if they’re only in it for their own fame and ego, then I don’t really care if they’re annoyed. I just want to entertain people and I’m lucky to get to do that on a big scale. But if I weren’t on the show, I would still be doing everything in my power to entertain people, even if it were on a much smaller platform, even if it were only for my mother.”

So with which character do you identify more: Spencer Reid or Simon the Chipmunk?
“It’s funny. I do see similarities between all characters I play. But Reid definitely is very different from me. I feel closer to Simon in many ways, to be honest, than I do to Reid, although I look more like Reid, of course. But it does feel like I put a costume on when I play him. When I look in the mirror, I realize I’ve become an entirely different person all of a sudden. It’s a strange feeling, but I’ve gotten used to it.”

Do you think, as an actor and a creative artist, that you have enough insight into the human condition that you could be a profiler?
“Well, I think I could fake it for a while. There are about 11 real profilers in the world. I’ve met six or seven of them. And after doing 110 episodes of the show, inevitably you find that you’ve learned quite a bit more than you ever thought you’d know about profiling. So I think I would be able to sort of get by. I think I could fake it for longer than anyone would want me to. But I think I prefer just to pretend.”
