Machine Gun Preacher

Machine Gun Preacher is a 2011 biographical action drama film about Sam Childers, a former gang biker turned preacher and defender of African orphans. The movie was based on Childers book Another Mans War. It was written by Jason Keller, directed by Marc Forster, and stars Gerard Butler, Michelle Monaghan and Michael Shannon.

Although the film centers on Childers, it starts off with a scene in South Sudan, where the LRA are attacking a village. This opening scene is placed into context later in the film. Childers was an alcoholic drugusing biker from Pennsylvania. On his release from prison, he finds that his wife has given up her job as a stripper, because she has since become a Christian. Eventually, after he almost kills a vagrant the night before, his wife persuades him to go to church with her, where he is eventually converted.Later, on a missionary trip to Uganda to build homes for refugees, he asks one of the SPLA soldiers watching over them to take him on a trip to the north, to Sudan. The soldier warns him that it is a war zone, but upon Sams insistence they go. They arrive at a medical tent in Sudan. As his friend moves off to talk came in to some people, Sam is roped in by a redheaded female doctor to help lift a lipless Sudanese woman onto the examination table. That night as they lay on their beds at the relief station, they hear noises outside, when they look out Sam and the soldier see large numbers of Sudanese children swarming in to sleep outside the building. ........
