Mark Ruffalo is in negotiations and Jake Gyllenhaal and Robert Downey have signed onto David Fincher's long-gestating thriller "Zodiac" according to The Hollywood Reporter. The Paramount and Warner Bros. co-production is aiming to begin filming in August.
Gyllenhaal will play Robert Graysmith, the journalist and author of the two books, "Zodiac" and "Zodiac Unmasked: The Identity of America's Most Elusive Serial Killer Revealed," upon which the film's script by Jamie Vanderbilt is based. Downey will play fellow reporter Paul Avery, and Ruffalo would play the San Francisco homicide inspector in charge of the case.
The books revolve around the real-life tale of a serial killer known as the Zodiac Killer, who terrorized San Francisco between 1966-1978 and had at least 37 murders to his name. Graysmith and Avery worked at the San Francisco Chronicle, which the killer used as a conduit to communicate with authorities. The former believed he had identified the killer but competing investigations and other circumstances prevented the suspect from being apprehended.
