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.

You always try and make a film that is a letter that will be read and we are so glad that it is being read by the right people in the right place and is inspiring change. It is also gratifying that the survivors are finding it healing and transformative. That's been really great.

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.

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.

Make sure it is not too diverse or spread out so people don't know where to go or what to do. So keep a sharp focus. It can be ambitious but should have a small agenda.

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.

Whenever I spoke with anybody who said they did not have a problem in the military it was because their commander treated them well. Every single time it was about the commander as to whether they had a good or bad experience.
