Documentary currently in post-production. Trailer here: http://www.youtube.com/watch?v=XAz2jUOmGlc
Judging by the trailer, it appears this documentary examines the dichotomy between Christianity as a peaceful religion and the violent/competitive world of combat sports. The deeper message explored seems to be whether today's Christian men have lost their masculinity. I am interested in it, although I don't know if there will be an Orthodox voice represented. Does seem to be a Catholic priest, though.
