"The Weather Underground is a 2002 documentary film based on the rise and fall of the American radical organization The Weathermen. The group's goal was to 'bring the (Vietnam) War home' through acts of domestic terrorism. The film, directed by Sam Green and Bill Siegel, was nominated for an Academy Award in 2004."
