My kids are not that interested in my movie career, by the way. My son, in particular, never talks about it. He just wants me as his dad.

I would love to have a robot at home.

The longer it takes you to become successful, the harder it will be for somebody else to take it away from you.

There is anxiety, but it comes after you've finished filming because it's out of your hands; people are editing it, they're cutting it, marketing it. And it's... part your career sort of rides on that. But when you're actually filming it's a team thing and it really feels good there for me.

There is still boxing, but there's just no money in it anymore. If you went around the world and asked a bunch of people under 20 years old, to name a boxer, I bet they couldn't name one. They'd be able to name a UFC fighter though. When I was younger there was Mike Tyson and we watched everything. I'm not saying its gone, or its going to go, and it could easily be ignited by another fighter, but it's just that idea that UFC is more violent, that desire for more spectacle, has captured people's attention.

To me, the smell of fresh-made coffee is one of the greatest inventions.

When I made 'Real Steel,' the director actually had the robots in the monitor, so he knew where everything was. So technically, there's been advancements. But at the end of the day, movies are about story and characters, so all the other stuff is great, but unless you have those two elements, then you've got nothing.
