I got a phone call from George Miller [the director] asking me to play this role. We sat down and he showed me on his computer a documentary-type montage sequence of real penguins swimming, in an Esther Williams synchronized sort of way, and doing things I have never seen them do. Then he explained his vision of the film, asked me to read the script and to voice the character. I was cast a little bit later, and he let me do the singing as well!

Sometimes we love people so much that we have to be numb to it. Because if we actually felt how much we love them, it would kill us. That doesn't make you a bad person. It just means your heart's too big.

Over the past year I'vediscovered if you keep on giving and giving, you end up losing yourself. I think that learning to give and receive is the trick. Perfect happiness is also a feeling, and the most amazing thing is that we were all born with the gift to make it happen in a heartbeat. Putting on certainmusic, reading something can make us feel a certain way. I think the key to happiness is allowing ourselves to not feel bad or guilty for feeling it, and letting it be contagious. And to not be dependent on other people to create your own happiness.
