“When your kids turn 13, an alien being invades their bodies and doesn’t leave until they’re 20.”

I had never really wanted to be famous. Everyone is supposed to want to be rich and famous, but as a boy I never knew what rich was, and the first view I had of famous made me leery.

When people are laughing, they’re generally not killing one another.

And I want to warn everyone in the press and all the voters out there: if you demand expressions of religious faith from politicians, you are just begging to be lied to.

You can’t get there by bus, only by hard work and risk and by not quite knowing what you’re doing. What you’ll discover will be wonderful. What you’ll discover will be yourself.

It makes it fun. When an actor plays a character, you want what that character wants. Otherwise it doesn’t look authentic. So I really want to defeat Jimmy – I mean Jimmy as the character.

People who laugh together generally don’t kill each other.

I’ve played a murderer, so certainly I think I can play a Republican.

Someone wrote a Wikipedia entry about me, identifying me as an atheist because I’d said in a book I wrote that I wasn’t a believer.

One day, though, I realized I was no longer a believer, and realizing that, I couldn’t go back.

Testosterone Poisoning: … Until now it has been thought that the level of testosterone in men is normal simply because they have it.

After a while I started to think of that as an image of something that went a lot deeper than the dead dog, which is you can’t bring back anything to life.

A really great actor, in a lucky performance, can transform himself or herself. I’ve seen actors do that.

I still don’t like the word agnostic. It’s too fancy. I’m simply not a believer. But, as simple as this notion is, it confuses some people.

I found I wasn’t asking good enough questions because I assumed I knew something.

I was always interested in figuring things out. I’d do experiments, like combining things I found around the house to see what would happen if I put them together.
