I love life, man, and I embrace every minute of it so maybe I bring that on the set. I love people and I want to have a good time.

It's been great, I have to dig deep for really raw emotions and at the same time I have to use my intellect to say the ridiculous medical jargon while acting and treating a patient and then I have to try to have a personality and emotions as well. So it is definitely hard work.

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.

I think as you mature as an actor things open up to you in a lot of ways, especially if you do work on yourself.

Bryan Cranston has got such an incredible light touch. He comes in egoless, but with bold opinions, and he wants to play. He wants to play. And that's what I've seen in great actors all my life and what I've always tried to nurture and keep in myself is that joy of playing.

After kids leave the house, they can decide to do whatever they want, but while they're under my roof, they're going to be lawyers or writers or something, something important, anything except actors.

Some kids are fine, but often I don't like what I see in child actors. My kids are young and they are already showing an interest, so I have to try to discourage them, squash that in them.
