Self-expression is something that you've crafted, something that you've found. You've practiced on that piano for hours, you didn't hang out with your buddies, you didn't go after the girls, you stayed in your own little geeky room or you wrote for hours.

I grew up with a lot of cats like that and they always were so surprising, magnetic, and electrifying. You can't be with them too long because they burn you out but the energy, the impulsivity, and the freedom connecting them to their animal energy is just so powerful to watch. It's dangerous to live like that but it's riveting to watch.

It's not quite the same as other kinds of performing, but I love animation. It is just a different kind of experience. The difference is that making a live action movie you are using your whole body.

It used to be trained professionals doing animation and they were great. Now they have celebrities and famous actors doing the voices, but that does not always work. But I think this film turned out really well, partly because the three of us (me, Ray and Denis) are comedians who are used to doing solo acts and doing certain types of voices. The three of us are New York guys, we all came up the same way in the profession and we are all edgy and enjoy doing family movies. It was a good combination I think.

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.

t is for me because I needed to do this. I really think actors shouldn't act unless they really need it in their lives. I think it has to be something that is so much a part of your chemistry, such a passion, that you can't live without it. You should not do it just because you are seeking fame or want to get rich.

You have the hilarity and the great production. These films are distinctive because they are not just topical, they tell good stories and they let scenes play out physically. Apart from the dialogue, the characters also have a non-verbal existence, for example with Scrat.
