You just want to go off and be intuitive and wild, and that's what Bryan Cranston brings to the game.

You have the hilarity and the great production. These films are distinctive because they are not just topical, they tell good stories and they let scenes play out physically. Apart from the dialogue, the characters also have a non-verbal existence, for example with Scrat.

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 really love it, I love working with directors that are very collaborative and allow me input. I've done over 75 films, it's just like you're an apprentice. You learn so much about camerawork, lenses, and I'm always talking about DPs and directors and they always give me lists. I think pretty soon, I'll be ready to move away from being in front of the camera.

I gotta tell, that's one of the things in Hollywood that has not been a barrier. I've gotten lots of offers, and I did try my hand at it, I directed two commercials. I won best commercial of ad week [laughs] on my first try.

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.

Marriage is wild. I thought it was this perfect land of happiness and joy. Wrong! After you say you do, you don't for a long time.
