The Human Rights Campagin posted a review of the film here.
Maybe we will see this new film (and the other two) on PBS POV, HBO, or CNN.
Update: Feb. 10
The full documentary that I watched has been suddenly removed by the user. It had been posted by "Geo A" on Feb. 7 and attracted over 51,500 views. The image still (as of 5 PM EST Monday) shows with a search on YouTube, but I suspect it will not show up there much longer. But I did find another video interview with Liz MacKean, from Britain here. The British journalist refers to the vigilante operation as self-called "Operation Pedophilia" and the undercover ops as "safaris". In Russian street thinking, there is no distinction between pedophilia and (male) homosexuality, and idea that does not have the support of reputable science. Note also the role of the Russian Orthodox Church, when the former Soviet Union was considered atheist.
Let's hope that a US group (like PBS) picks this up and airs it soon. Or else, get a film distributor to show it in theaters and make a DVD. I'll see what I can do, by networking, to get this film made available in the US.
Update: Oct. 4, 2014
HBO will air a full 60-minute version of the documentary Monday Oct. 6, 2014. Variety has a review here, The HBO link is here.
Note: Feb, 21, 2015
I am told that Channel 4 in Britain is not part of the BBC.
