I don't know if tennis players feel like that but when you have a great opponent - although I didn't feel like he [ Ben Mendelsohn ] was an opponent - you just know your game is going to jack up and it's just going to raise the bar. I couldn't wait for that elevation.

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.

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.

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.

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.

I did the bible as told through Hispanic people and they laughed and applauded. I thought, "Oh my god, this is what I want to do for the rest of my life."

The thing I gravitated to was being the class clown. It was very competitive.
