Ben Affleck went in front of the UN yesterday to present a short film he directed, with the help of Mick Jagger and cinematographer John Toll, to launch a new $23 million initiative [1] to help Congolese refugees. The short, "Gimme Shelter" is set to the classic Rolling Stones song used with permission, and was shot last month when Affleck made a trip to visit refugee camps [2] in the Congo. From here, the film will be released worldwide to help raise awareness about UNHCR and the needs of the 1.3 million displaced people in the area. Check out the video below and let us know — do you think it's effective?
