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.

It's all about respect; he's looking for respect from his buddies. In the last one he just wanted to hang out, to be part of the group, but this time he wants more from his friends. And without giving the story away, he finally gets something that he has been looking for when the mini sloths kidnap him and take him to their tribal area. He gets to be the Fire King and they worship him and there is an amazing scene with a "call and response" sequence in the style of Cab Callow [the legendary American jazz singer and band leader] between him and his audience.

Sid [the character from 'Ice Age'] is a prehistoric sloth. Sloths move really slowly and they store food in the cheek pouches. That's where I got the voice that you hear. He had to sound as though he was storing food.

It used to be trained professionals doing animation and they were great. Now they have celebrities and famous actors doing the voices, but that does not always work. But I think this film turned out really well, partly because the three of us (me, Ray and Denis) are comedians who are used to doing solo acts and doing certain types of voices. The three of us are New York guys, we all came up the same way in the profession and we are all edgy and enjoy doing family movies. It was a good combination I think.

At Murry Bergtraum [High School] if you were really funny you sat at this table at with all of the funniest dudes, the toughest, the coolest - everybody sat at that table. It was like the ghetto Algonquin Round Table. [Comedy] was my entry, my membership card.

I'm not really against a lot of things unless they are just pure exploitation and then they create their own copycat culture that comes from someone acting irresponsibly. That's dangerous when that happens.

Most of the great directors I've worked with - De Palma, Spike Lee - like rehearsals.
