The message is one of the beautiful things about the film. And I think part of the appeal is simply that they are prehistoric creatures, they are no longer around and that makes them magical and makes us feel quite emotional, because we know that those creatures did not survive in the long run, so there's poignancy in their fight for survival.

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.

It's all about respect; he's looking for respect from his buddies. In the last one he just wanted to hang out, to be part of the group, but this time he wants more from his friends. And without giving the story away, he finally gets something that he has been looking for when the mini sloths kidnap him and take him to their tribal area. He gets to be the Fire King and they worship him and there is an amazing scene with a "call and response" sequence in the style of Cab Callow [the legendary American jazz singer and band leader] between him and his audience.

Tennessee Williams, one of my favorite playwrights, [lived] down there. You always heard about the Keys and how amazing they are and, well, it's like a highway with some bars on it.

I love cartoons. So when they came to me to make Ice Age and this sequel, I was so happy.

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.

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.
