The Zodiac Killer is a 1971 horror-thriller movie directed by Tom Hanson. The film is based on the true story of the unsolved Zodiac murders that happened in San Francisco in the late 1960s and early 1970s.
The movie follows the investigations of a group of police detectives who are trying to solve the case of a series of murders that have been committed by a mysterious killer who calls himself the Zodiac. The Zodiac Killer sends letters and cryptograms to the police and the press, taunting them and claiming responsibility for the murders.
The main suspects in the case are a violent truck driver named Grover and a seemingly mild-mannered mailman named Allen. The detectives also suspect that the killer may be a cop, as many of the murders happen in areas that are patrolled by the police.
The movie depicts the tension and fear that the Zodiac killer brought to the Bay Area during his killing spree. The detectives work tirelessly to catch him, but despite their efforts, the killer remains at large. The Zodiac Killer is known for its gritty, documentary-style cinematography and its chilling portrayal of the real-life terror that gripped San Francisco during this time.
The movie's ending is particularly haunting, as the killer's identity remains unknown and the case remains unsolved. The Zodiac Killer has become a cult classic among horror and true crime fans, and is often cited as one of the most suspenseful and terrifying films of the 1970s.
