When you're writing is when the "god should I just drop this" feeling can hit. When you're editing is when the "god this is awful and I've wasted everyone's time and money and will be revealed as a fraud" feeling can hit.

I think what I love about science fiction and what sci-fi can be really good at is obviously you're working with outlandish concepts that have very little to do with the real world, like time travel for instance.

You go from these high hopes when you're writing to just a desperate want of not making a complete fool of yourself by the end of it.

Much of directing [a movie] is not directing but just listening and being present in the moment and just keeping your eyes open.

Even if I had $200 million, I’m very wary of overusing CGI. I think it’s a great tool and it can be used really effectively, but I feel like it does tend to be overused and especially in sci-fi stuff.

With 'Brick,' I wrote the script when I was 23 and didn't make the movie until I was 30.

I'm a sci-fi fan, and I guess you have to let go of some of that at some point, and realize that as long as you're focused on telling a story that you care about, at the end of the day, that's what really matters, even to hard-core sci-fi fans.
