With kids, the days are long, but the years are short.

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.

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.

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.

That's the happiest I am, when I'm doing great work.

I love his [Brad Furman] ferocious desire for perfection and his love of vitality, it feeds me, man. It feeds him and it feeds the whole crew. And he's got huge respect for talent. And that's why talent goes in and gives it 300% percent.

It's the flip side of illegal success. This man [Pablo Escobar ] turned a small-time drug thing into a large industry. An international, successful industry. And he almost took a country, Columbia, he took it almost hostage, took over it. It was incredible.
