An undated handout photo shows Pastor Dione dos Santos (R) talking with an armed drug trafficker in Vila Alianca during a scene of the documentary "Dancing with the Devil," which premiered at Rio's annual film festival on October 4, 2009. The film traces the daily lives of three men caught up in Rio's violence -- a drug lord, a police officer and an evangelical pastor. The movie is one of two very different movies showing an ugly, violent side of Brazil that many would rather forget as the country prepares to host both the World Cup and the Olympics within the next seven years.
