I should have done it years ago. It's amazing I didn't even want cigarettes anymore.

Now that I have kids, I'm probably more overprotective than I've ever been. My wife's nickname for me is "red alert." I sometimes check just to see if the kids are breathing. But I try not to be a helicopter parent.

I've gotten much better at multi-tasking. It's hard, though. But, writing a script is not totally focused. You're taking little breaks, all the time. If a kid runs in, you give 'em a horsey ride. It's a pretty fluid process.

I'd love to be a dad. I hope I'd be great at it. That's every man's fear, yet his most important job.

For a lot of actors, our biggest fear is that we're going to start talking about things we don't fully understand and sound like idiots.

Still, the change is nearly indescribable - going from total obscurity to walking down a street in New York and having everybody turn and look; to feel the temperature of a room change when I walked in.

The only sci-fi movie that I've ever been offered that, had circumstances been different, I would have definitely done, was 'Avatar.' And I literally couldn't do it because of my schedule. But listening to James Cameron talk about 'Avatar' was so fascinating. Because he literally invented the world in his mind - and it literally existed.
