I'm willing to engage or indulge real ideas, but if we don't do something [about global warming], we're all going to die! What's it going to take, a big f--ing disaster with all kinds of people dying? We need to change our priorities fast.

The future is not set. There is no fate but what we make.

There seems to be a lot of excitement around something that, to me, is a yawn, frankly.

Don't get seduced by your own stuff. Don't get high on your own supply. The hardest thing as a filmmaker is when you're watching a film that you've worked on for several years. You know every frame so intimately that holding lots of the objectivity of a new viewer who has just seen it for the first time is the hardest thing. Every aesthetic decision you make - and you make thousands of them every day, have to - in theory, must be done from you being a blank slate. You almost have to run a program, like a mind wipe, every time you watch the movie.

I've tried not to get sucked into the Hollywood hierarchy system. Personally, I don't like it when people are deferential to me because I'm an established filmmaker. It's a blue-collar sensibility.

Getting the audience to cry for the Terminator at the end of T2, for me that was the whole purpose of making that film. If you can get the audience to feel emotion for a character that in the previous film you despised utterly and were terrified by, then that's a cinematic arc.

You have to not listen to the nay sayers because there will be many and often they`ll be much more qualified than you and cause you to sort of doubt yourself.
