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.

When I started performing I was like, "Holy hell, how am I going to survive this?" I was giving it my all in 15 minutes but now I had to do it for two hours.

I like drama. I love being in a drama where I get to be the funny guy. That's what I really love the most.

I have a lot of heroes. I don't think people give enough of a tribute to their mentors. They try to act like they're spontaneous generations - they are faking liars.

I wanted to enjoy the process. I wanted to enjoy just being on stage and giving back and the feedback.

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.

When you feel the world is against you or you give up hope, you look at your heroes and say, "They were able to do it. They had hard times and a lot of opposition, but they got through it." Then you feel, "I can do it too."
