I love his [Brad Furman] ferocious desire for perfection and his love of vitality, it feeds me, man. It feeds him and it feeds the whole crew. And he's got huge respect for talent. And that's why talent goes in and gives it 300% percent.

But when you are doing an animated voice, it has to have more energy than usual or it falls flat and doesn't work. For myself, I found that I had to put myself in the same physical or emotional state as Sid, in order to make that voice sound alive and authentic. So if there was a scene in which he was running, I would be running beforehand to sound out of breath. That's important because the audience can tell intuitively if it does not sound real.

Rehearsals make a huge difference.

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.

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.

Acting is kind of a calling for me so I'm just happy to be there and do great work.

There were no Latin people on 'Star Trek,' that this was proof that they weren't planning to have us around for the future.
