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.

Voices come to me but to maintain them is hard work. They go away just as easily, so I have to remember them and that takes work. With Sid, I needed to make sure you could understand what he is saying, his enunciation. Sometimes I couldn't even say my own name [his name] in his voice. It sounds like 'Shid', it sounds a bit like he has a lisp.

America may not realize it yet, but Latin prototypes are being created right now, and not just by me. They are these mambo kings and salsa queens, Aztec lords and Inca princesses, every Hernandez and Fernandez, whom this country will one day come to understand and respect.

It's a product of being an actor, you know? A lot of your work doesn't end up on camera and some of the best things aren't always in the final product. But yeah, a lot of my stuff got cut and it was painful, but I know it was for the better of the movie.

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.

Great acting is being able to create a character. Great character is being able to be yourself.

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.
