It was pretty much the last person we found - an independent financier who paid for the whole thing out of his pocket.

But my mother's a psychologist, my stepfather's a psychologist, my stepmother is a therapist and my dad's a lawyer. So it was all prominent in my life. I don't know anyone who doesn't know someone on some form of prescription medicine.

They're huge shoes to fill ... if people see any similarities, he was a goofy guy who wasn't your stereotypical magazine poster boy, but he had the ability to be a great everyman. If I can set out to do anything in my career, it would be to play people that the people can relate to. Those are the parts I'm most interested in doing.

It used to be that you came out of school, and you got married - those who were going to get married. But my peers are getting married in their early 30s, so now there's like this extra 10 years of that angst.

I wish I was that important of an actor that that happened. 'Which do you want Zach? Take your pick.' No. I sort of put it out there that I wanted to do an animated movie. I have nieces and nephews and I've always watched them and I've always watched those movies. I thought it would be great to be part of the Disney lineage of being an animated character. When this project came up, I asked to audition. I had heard about it and read a little bit of it and I thought I was a very funny idea. The idea of not just doing a Chicken Little story. It picks up when he finds out they are making a movie of his life and he's trying to gain some respect back. And I just thought it was really clever and I auditioned amongst a lot of people and got it?I've been involved for about two years. As you know, they've been doing it for about five years. But I've been recording voices on and off for two years. Probably every other month. Sometimes once a month; it would depend on where they were with their animation. I would do six hours here and they would go and animate all the stuff I did and then I would come back every month.

I'm by no means condemning prescription medicine for mental health. I've seen it save a lot of people's lives.
