Being able to just stick to our instincts and honor the [Hunger Games] books and find a way to stay the course of trying to make the best possible decisions that you would make creatively on any movie, without having your head turned too much by all of the interest, has been a great challenge.

It's a similar feeling from being in a community of punk rockers as a teenager and the feeling I still get today when I'm in a community of skeptical scientists.

It's a process of collective discovery. It's debate, it's experimentation and it's verification of claims that might be false. It's the greatest foundation for a society.
