I had to get the voice back, the precise pitch of Sid's voice and I'd forgotten that I'd pitched him higher than my regular voice, so that was a little difficult to begin with. It was especially hard because we started recording in the morning so I had to warm up a lot and my usual voice is a little more gravelly.

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.

We see them [animals] as the Ice Age is ending and we know that actually in the long run, they're not going to make it. And there's something beautiful about that, beautifully sad. The way the characters are woven together in the film adds to the emotion because they need each other. The message is that it doesn't matter what species you are, you can still love each other and that is a fantastic message.

I gotta tell, that's one of the things in Hollywood that has not been a barrier. I've gotten lots of offers, and I did try my hand at it, I directed two commercials. I won best commercial of ad week [laughs] on my first try.

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.

I was always writing. I was writing in high school because it was a really competitive school for class clowns; I used to have to write all of my snaps and my disses the night before and then act like I was making it up the next day.

The beautiful thing about acting is that you can go your whole life if you stay current and you stay fresh.
