Hmm, that is a very thoughtful and moving trailer. I hope the filmmaker is able to raise funds for the documentary.
Here is a trailer for a short documentary made a few years ago, which went on to win an Academy Award, and many other awards at film festivals. This trailer makes me cry every time I see it:
I met the filmmaker at a function once, shortly after she won the Oscar. It was a fundraiser for a women's filmmaking group and everyone was oohing and aahing when she walked by, "Oooh, here comes Cynthia Wade!" She's super nice and I think did a great job. She's going to produce a feature film adaptation of the story with Ellen Page as Hester's lover Stacie Andree.
A narrative feature will bring even more attention to the issues, so that's good.
