I would hope with all my heart that people understand this and see it in the film. And there are also other messages in Happy Feet, like racial and environmental ones, but none of them are so overt. George has made a great story about penguins with a lot of humanity in it and audiences can follow a species we don't know that well.

I've been singing my whole life, since I was a kid; but never formally as a career. I did it in plays when I was younger, and I sang all styles of music: everything from Italian opera to blues.

Tired is not a word in my vocabulary.

I do sarcasm really poorly.

I don't really take myself very seriously.

I am an eternal optimist. Being happy is a choice. And you can make that choice every day, if you want to.

And as much as I love the gritty characters, I like to play all sorts of characters. I'm an actor. I love to create.
