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.

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.

Me and Kirby are very collaborative and it changes from film to film. The first project we worked on together, Derrida, we co-directed. The last film Outrage, I was the producer and he was the director. This film was much more of a collaboration - he is the director and I am the producer - but this is a film by both of us.

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.

Things can change if the military can do a paradigm shift and gets out of the shame and coverup cycle and be a leader in our culture. In the 50s, 60s and 70s there were huge race problems in the military even more severe than the culture at large. The military saw it was detrimental and it changed and became a model to society at large.

Be very focused. Do your homework so your research and claims are unassailable. Make sure it is bulletproof and then make sure you are really focused. The thing I find is that the issues are usually so large that you try to cover a lot of ground. That's a natural impulse.

One of the top challenges is the fact that you are dealing with survivors. Every time you deal with a documentary film subject it is fraught with obvious minefields but when you are dealing with a population that is severely traumatized and trying to recover from that trauma there is an extra level of vigilance and care and attention that has to be implemented all the time at every level.
