The Warriors is a 1979 American cult action thriller drama film directed by Walter Hill and based on Sol Yurick’s 1965 novel of the same name. Like the novel, the film borrows elements from the Anabasis by Xenophon. The film opened on February 9, 1979 in 670 theaters without advance screenings or a decent promotional campaign and grossed USD $3.5 million on its opening weekend. The following weekend the film was linked to sporadic outbreaks of vandalism and three killings; two in Southern California and one in Boston, involving moviegoers on their way to or from showings. This prompted Paramount to remove advertisements from radio and television completely and display ads in the press were reduced to the film’s title, rating and participating theaters. In reaction, 200 theaters across the country added security personnel. Due to safety concerns, theater owners were relieved of their contractual obligations if they did not want to show the film, and Paramount offered to pay costs for additional security and damages due to vandalism.
