One of SXSW's prize winning documentaries is finally coming to the masses. This Wednesday (March 25), HBO2 will be premiering Daniel Junge's documentary They Killed Sister Dorothy at 8:00/9:30 p.m ET/PT. It will get a handful of replays, so check HBO's schedule and your local listings if you miss it on the first try.

Junge's documentary examines the life and brutal murder of Sister Dorothy Stang, a 73-year-old nun from Ohio who was shot to death in an Amazon jungle. Three men were eventually convicted of killing her, and the Brazilian government stepped up to continue her work in preserving the Amazon rainforest.

Kim Voynar reviewed the documentary at SXSW last year, and was full of praise for its tight style and clear narrative: "They Killed Sister Dorothy isn't just a film about a nun thwarting the attempts of honest ranchers to simply make a living; at its heart, this is really a story about the wealthy versus the poor, and about an activist trying to protect a natural resource from those who would destroy it for profit."

The other five reviewers collected by Rotten Tomatoes all found it equally riveting, which suggests we should all check it out. Sister Dorothy Stang was willing to die for her cause and no matter what your feelings on environmental issues might be, her story is worth knowing and remembering.
