In the King of Prussia (1982)

In the King of Prussia is a 1983 film directed and written by Emile de Antonio. The film reconstructs the events of the 1980s "Plowshares Eight." The group of anti-war activists were charged with the September 1980 destruction of nose cones designed for nuclear warheads at the Re-Entry Division of the General Electric Space Technology Center in King of Prussia, Pennsylvania. The members of the Plowshares Eight, including Daniel Berrigan and Philip Berrigan, played themselves while actors played the roles of jurors, lawyers and police; Martin Sheen played the role of the judge in this shot-on-video feature.
