Hollywood is an illusion. These intense workplaces, with very close relationships, a few months at a time - and then it ends.

For a long time, it was like I was part of some special forces unit: I'd land, meet everyone, five minutes later I'd have to do some amazing work, then - boom! - I'm out again. You know, playing supporting parts takes courage.

You know, the truth is that us actors would all like to believe we re-invent the wheel, every time we play a character. But, we're human beings and our instruments are not violins, they are our bodies and our consciousness and our collective life experience.

When I first joined SAG, there was another John Reilly. My dad was John Reilly, too, but growing up I was John John. Nobody in life calls me John C. It's more like, "Hey you, Step Brother!"

Kind of the exhausting thing about doing pure comedy, or something that's broader, is you're kind of a slave to the laugh. If it's not funny, then there's not much point in doing it. The kind of über-objective is to make people laugh. You always have to have that in the back of your mind, "Eh, I've got to figure out a way to make this funny."

Unless you do the same thing, it's tough for stereotypes to stick. That said, whatever you've done that's most popular at a given moment is what people think "you do."

Movies are this thing that came into my life, and it still feels pretend in some way. I kind of do this thing, and I never really accepted this idea that I'm a film actor. That's what I do. I feel like I'm a theater actor that started doing films. Most people have never seen me in a play. They're fun, though.
