I walked around my apartment with food in my mouth asking myself: "How do I come up with this voice?" Then I found the voice. I called the director and said on the phone: "Guess who you're talking to Chris? Sid, that's right Sid!" And that's how I came up with the voice. That's a true story.

It doesn't make sense. [Republicans are] not for us. You're not for my values. We're working class people mostly and blue collar.

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

I'm just more comfortable with people who are like me than the people who are not.

The way the characters are woven together in the film adds to the emotion because they need each other. The message is that it doesn't matter what species you are, you can still love each other and that is a fantastic message.
