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.

I did 40 voices for Chris Wedge, the director of the first film, before coming up with the version we used. He was hard to please, I don't know why. I gave him really slow talking voices. then I thought perhaps Sid could be an Indian sounding sloth. To find out more about my character, I watched footage of sloths. I discovered that the food they store in their pouches rots and ferments and half the time they're drunk.

I had to get the voice back, the precise pitch of Sid's voice and I'd forgotten that I'd pitched him higher than my regular voice, so that was a little difficult to begin with. It was especially hard because we started recording in the morning so I had to warm up a lot and my usual voice is a little more gravelly.

I grew up with a lot of cats like that and they always were so surprising, magnetic, and electrifying. You can't be with them too long because they burn you out but the energy, the impulsivity, and the freedom connecting them to their animal energy is just so powerful to watch. It's dangerous to live like that but it's riveting to watch.

I'd be terrified even now for a Latin kid wanting to be an actor, but back then? Forget it. They must have thought I was going to be working in restaurants and driving cabs for the rest of my life.

The beautiful thing about acting is that you can go your whole life if you stay current and you stay fresh.

I like helping people achieve their dreams just like people helped me.
