Jake Gyllenhaal returns to the big screen with sure success in Zodiac, a low-key thriller centering around unsolved murders in California from 1968 to 1969. The star-studded cast in this 2007 movie includes Gyllenhaal as Robert Graysmith, Mark Ruffalo (Rumor Has It, Just Like Heaven) as Inspector Toschi, Anthony Edwards as Inspection Armstrong, and Robert Downey as Paul Avery. The Zodiac killer’s numbers were not what made the case so chillingly unforgettable – only five known victims fell to the serial killer’s wicked ways. The Zodiac took his killing one step further, even going so far as to mock police and public alike with strange, coded messages in the newspapers. The case was moved to the inactive files of the San Francisco Police Department in 2004, and to this day it remains unsolved. For many reasons, the self-named Zodiac is one killer that has captured public imagination time and again. The 2007 movie Zodiac, which was given a whopping four stars by TV Guide reviewers, should not be confused with the movie The Zodiac (neither the 1971 or 2006 versions). The chilling tale in Zodiac will be neither gory nor horrific, but rather lead viewers through a darker, more mellow version of fear.
