There is a vast frontier that's going to take us a while to understand... it was very lunar, a very desolate place, isolated.

What are you gonna do, talk the alien to death?

We have a great responsibility. Whatever we make will become the truth, the visual reality that a generation will accept.

Here's my philosophy in life: If there's a fire, you put it out. If there's a flood, you fill sandbags and you build a dike. You roll up your sleeves and you get to work.

The literature now is so opaque to the average person that you couldn't take a science-fiction short story that's published now and turn it into a movie. There'd be way too much ground work you'd have to lay. It's OK to have detail and density, but if you rely on being a lifelong science-fiction fan to understand what the story is about, then it's not going to translate to a broader audience.

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.

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