I used to work as a private detective years and years ago. And my boss gave me this one very simple piece of advice about trying to figure out who to interview first in any investigation. His recommendation: Always pick the people who were fired. Pick the people who are pissed off.

Think of my movies as heightening our awareness, not confusing the difference between truth and fiction, but heightening our awareness of how confused we can become about what is real.
