I'm a big history buff so to walk the streets...the ancient world like that was pretty astounding.

Global warming is not only the number one environmental challenge we face today, but one of the most important issues facing all of humanity... We all have to do our part to raise awareness about global warming and the problems we as a people face in promoting a sustainable environmental future for our planet.

There's a difference in our ages [with Leonardo DiCaprio], but we were both in the same sort of position [on The Quick and the Death movie].Everyone below us in a casting position were all these really famous character actors like Keith David. And they were looking at the two of us going, 'Who are these guys?' So that naturally kind of put us together in a way where we'd just hang out together because we didn't care about status. We just wanted to enjoy the experience. The two things that have changed about Leo [ DiCaprio] since that time: he can drink legally and he's no longer a virgin.

You can make history, or you will be vilified by it.

It's very, very rare in this business [moviemaking] where a script lands on your lap ready to go.

[Success] always starts with the material; it always starts with the truth and honesty of the characters that you read in the screenplay and that's rarely something that can be remedied if it's simply not there by the time you shoot the film. Thank God we had that.

I've got this reputation for shooting one take which is a wonderful reputation to have but it's hard to live up to.
