Underground is a 1976 documentary film about the Weathermen, the militant faction of the Students for a Democratic Society (SDS) who fought to overthrow the U.S. government during the 1960â€™s and 1970â€™s. The film consists of interviews with members of the group after they were forced underground and footage of the anti-war and civil rights protests during this time period. It was directed by Emile de Antonio, Haskell Wexler and Mary Lampson, who were subpoenaed by the Federal Bureau of Investigation in an attempt to confiscate the film footage in order to gain information that would help them arrest the Weathermen.
