I love life, man, and I embrace every minute of it so maybe I bring that on the set. I love people and I want to have a good time.

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 did Brad's first film The Take and I'm glad Brad [Furman] has not calmed down. I don't want him to ever calm down.

Yes it did really. It was very exciting to find that my energy could be directed into something more useful and positive. I was starting to get panicked. I was thinking 'what am I going to do with my life?' I wasn't sure what was going to happen. Then I became crazily obsessed with acting. I suddenly had a work ethic and then everything changed completely for the better because I knew what I wanted to do with my life.

It's been great, I have to dig deep for really raw emotions and at the same time I have to use my intellect to say the ridiculous medical jargon while acting and treating a patient and then I have to try to have a personality and emotions as well. So it is definitely hard work.

Self-expression, to me, is something that you worked on, that you have mastered a skill to say something in the most artful way that you can. It's not just blurting stuff out and having verbal diarrhea.

Marriage is wild. I thought it was this perfect land of happiness and joy. Wrong! After you say you do, you don't for a long time.
