Zodiac - Director's Cut (Blu-ray)

During the 1960s and ‘70s, a serial killer, known only as “the Zodiac”, has the San Francisco bay area in a clutch of terror, killing innocent people uncontrollably and taunting police and journalists with letters, clues and cryptograms. Several jurisdictions become involved in the sensational mystery, but the culprit continues to evade the authorities.

Two journalists and two police officers become obsessively involved in the case. Highly intelligent editorial cartoonist, Robert Graysmith (Gyllenhaal), and self-destructive ace reporter, Paul Avery (Robert Downey Jr) are among the primary recipients of the killer’s many messages to their newspaper, the San Francisco Chronicle. The two begin to gather as much information about the case as possible.

Meanwhile, skilful homicide detective, David Toschi (Mark Ruffalo) and his partner, Bill Armstrong (Anthony Edwards), are equally consumed by the harrowing circumstances as they delve deeper into the investigation. The four men will become dangerously immersed in the puzzling case, which will either build or destroy their careers in the process.
