Rehearsals make a huge difference.

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.

I did 40 voices for Chris Wedge, the director of the first film, before coming up with the version we used. He was hard to please, I don't know why. I gave him really slow talking voices. then I thought perhaps Sid could be an Indian sounding sloth. To find out more about my character, I watched footage of sloths. I discovered that the food they store in their pouches rots and ferments and half the time they're drunk.

I've been hurt so many times I don't have the balls for it anymore.

I love theater. I think theater, when its done right, is the best, like a religious experience. When it is done badly, it's the worst thing. It's just an incredible experience.

Some kids are fine, but often I don't like what I see in child actors. My kids are young and they are already showing an interest, so I have to try to discourage them, squash that in them.
