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.

Rehearsals make a huge difference.

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 wasn't even in a theater because I guess nobody believed in me, so I was in the hallway of a theater on a platform that they would move so the main stage show could go on at eight o'clock and I'd be gone.

The New York Times made you or broke you.

Bryan Cranston is generous, he's funny. When we did a wedding scene [in The Infiltrator ], at the end of the movie with a big set piece, he put the veil off the bride, he put it on, he pretended like we were getting married, he's just a goof.

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.
