Water is an issue, and, clearly, what's happening with the filth in our environment and the levels of carbon monoxide in our atmosphere are the really scary issues right now, the very troubling ones.

Once the steam engine went away and we started moving into burning fossil fuels - not just burning them, but everything we do with oil - we've been experiencing [these problems] at an accelerated rate. The scary end-game scenario is getting closer and closer, about what we're going to be able to do to sustain life on this planet as we have come to know it. And I think this is a very real possibility, that we could be dealing with conditions we have no idea how to wrestle with.

Kids clearly help center you because you can't impress your kids. People are like, "Oh, are they so excited because you're Ironman?" My kids couldn't care less. They like it when I hang out and play dad. I impress them by playing video games with them and doing well. Your kids humble you.

We're always trailing, as far as the amount of roles that are written for us and the films that are being made that have black characters in them. I don't know if that's going to change.
