Go drive my Paramount Studios on Melrose in California and what will you see? How about a giant billboard for David Fincher’s Zodiac?! Inside you can take a look at what should be the new poster image for the film that stars Jake Gyllenhaal, Mark Ruffalo, Robert Downey Jr., Anthony Edwards and Ezra Buzzington. As a serial killer terrifies the San Francisco Bay Area and taunts police with his ciphers and letters, investigators in four jurisdictions search for the murderer. The case will become an obsession for four men as their lives and careers are built and destroyed by the endless trail of clues.
