Johnny Got His Gun (1971)

Johnny Got His Gun is a 1971 American independent epic anti-war film written and directed by Dalton Trumbo, in his directorial debut, based on his 1938 novel of the same name. The film stars Timothy Bottoms, Kathy Fields, Marsha Hunt, Jason Robards, Donald Sutherland and Diane Varsi. It was Trumbo's first and only directorial effort.
Although a minor success on initial release, it was largely forgotten soon after by mass audiences. It regained public recognition when clips of it were incorporated into the music video for Metallica's song "One", whose popularity subsequently turned Johnny Got His Gun into a cult film. Eventually, Metallica bought the film rights in order to keep showing the music video without having to pay additional royalty fees.
