Warner Bros. Pictures and Paramount Pictures are in advanced talks to co-finance Zodiac, a thriller detailing the obsessive efforts of three people who sought to bring the famed Zodiac killer to justice and the toll it took on their personal lives. The serial killer terrorized the San Francisco area from 1966-78 by killed at least 37 people. Variety reports that David Fincher is in negotiations to helm the film. Warner Bros, Paramount, and Fincher recently coalesced around The Curious Case of Benjamin Button, but that movie evaporated after the studios declined to spend more than $150 million on the special effects-heavy tale. Zodiac is adapted by screenwriter Jamie Vanderbilt (Basic) from Robert Graysmith's 1986 true-crime tome "Zodiac" and its 2002 sequel, "Zodiac Unmasked: The Identity of America's Most Elusive Serial Killer Revealed." Graysmith's first book has sold more than 4 million copies. Paramount will handle domestic distribution while Warner will handle international.
