When it comes to casting, I've been so lucky. I've worked with unbelievable actors who make me look better than I am and take the written word and make it honest.

Well, Toronto, I consider to be the birthplace of my films. I've made three films and this is the third one to premiere here in the same theater on the same day at the same time - they are my audience. They're the people that I think about while I'm writing, directing, and editing. I specifically make movies for them.

And the biggest improvement I see between 'Up in the Air' and 'Juno' and 'Thank You for Smoking' is that 'Up in the Air' deals with the complicated human stuff in a way that my other films have not. It's a more articulated film, and because of that, I'm most proud of it.

I remember when I was like 19 years old and I started a desk calendar company to pay for my first short film, just so I could say one day that my daddy didn't pay for my first short film. And I really established myself in the film festival world.

I laugh a lot in horror films. If I'm scared in a horror film, I try to think about what's scaring me... particularly, if it's a bad movie, but something they're doing still works. It's the same way I look at comedy. I've always had an intellectual view of comedy, and what makes people laugh, and how does it work.

If someone else made 'Up in the Air' or 'Thank You For Smoking' or 'Juno,' I would have wanted to rip their head off. I need that same sort of passion for every project I take on.

Growing up the son of a director has made me very aware of the various turns that a directing career can take. Sometimes your films turn out exactly as you want. Sometimes they don't. I spent a lot of my childhood on sets. I think as a joke, my father gave me a line of dialogue in each of his films during the worst moments of my puberty.
