Well I was about to be expelled from school, I had been arrested and a teacher said: "Why don't you try acting, instead of distracting the class? Why don't you use your comic talent for something more productive?" My maths teacher suggested I do comedy and I decided to have a go. I pursued it after that. I was about 17.

But when you are doing an animated voice, it has to have more energy than usual or it falls flat and doesn't work. For myself, I found that I had to put myself in the same physical or emotional state as Sid, in order to make that voice sound alive and authentic. So if there was a scene in which he was running, I would be running beforehand to sound out of breath. That's important because the audience can tell intuitively if it does not sound real.

It was at a performance art space that's no longer around, Gusto House... All of these great performers from all over the country lived on the Lower East Side, and they would take somebody's living room that opened right onto the street, open the door and charge tickets and put up chairs.

Sid [the character from 'Ice Age'] is a prehistoric sloth. Sloths move really slowly and they store food in the cheek pouches. That's where I got the voice that you hear. He had to sound as though he was storing food.

We are taking our culture and suturing it to America. Like gum on the bottom of a shoe, we are not going to disappear. Unlike other peoples who totally assimilated, we are more interested in co-assimilation.

I like drama. I love being in a drama where I get to be the funny guy. That's what I really love the most.

When I started performing I was like, "Holy hell, how am I going to survive this?" I was giving it my all in 15 minutes but now I had to do it for two hours.
