The difficulty is the levels of secrecy we had to maintain around the project at all different times. We had to keep it a secret while making it so we could move under the radar so we could get the stories. Before it came out we had to keep it on lock down to protect the safety and security of some people who appear in the film.

It doesn't happen often, it's what you dream and hope for. We are happy, but we want to make sure these changes have teeth. What we want to get across most is that this is a real opportunity for the military. They can step up and be a leader on misogyny and gender issues.

Figure out the one solution - not three - that you want to see happen. There were quite a few things we could have gone after but we decided to focus on the commanders and that was a strategic decision because that, for us, would be the most vulnerable point and the most effective one that could immediately change.

When I talk with women who have had wonderful experiences in the military it's because their commanders treated them with respect and dignity and gave them equality with their peers that was unparalleled in their lives.

[Working with survivors] it's just a whole different level of concern and that is something that was categorically different working on this film than any other project we had done.

We really want to send the message that commanders need to understand and be accountable. We saw that with the Catholic Church. No one cared when they went after the priests, but when they focused on the bishops then things began to change. And we see that analogy working with the military.
