The film that won Best Documentary, and I felt should have won Best of Festival (it was the runner up) was clearly the best film I saw there, head and shoulders above the rest.
A Cry From Iran is a 52 min. documentary on the life and death of Haik Hovespian, a Christian pastor and head of the church in Iran who was martyred in 1994. The film is by his sons.

I can't say enough about how powerful it is. It doesn't attack those who martyred this man, but gives the story with hope, telling of who he was, and what he believed, and how his death has strengthened the church in Iran. The production values are wonderful (the brothers are film producers by profession) but the story is so powerful. When the film won Best Documentary the brothers received a standing ovation.

Talks with several distribution companies are in the works, so pray for them. You can pre-order the film on the website.
