I feel like I barely survived Django (Unchained) emotionally - the violence, hearing the N-word every day. It cost me a lot psychologically, but it was worth it to tell that story.
There are people who travel because they want to push themselves to physical limits, people who walk across deserts or cycle across the Antarctic - like Ranulph Fiennes, who just does it because it's there. And then there are people like me, who are just genuinely curious about the world.
