Zodiac

Zodiac is a 2007 American crime thriller film directed by David Fincher and written by James Vanderbilt, based on the nonfiction books by Robert Graysmith: Zodiac (1986) and Zodiac Unmasked (2002). It stars Jake Gyllenhaal, Mark Ruffalo, and Robert Downey Jr., with Anthony Edwards, Brian Cox, Elias Koteas, Donal Logue, John Carroll Lynch, Chloë Sevigny, Philip Baker Hall, and Dermot Mulroney in supporting roles.

The film tells the story of the manhunt for the Zodiac Killer, a serial killer who terrorized the San Francisco Bay Area during the late 1960s and early 1970s, taunting police with letters, bloodstained clothing, and ciphers mailed to newspapers. The case remains one of the United States' most infamous unsolved crimes. Fincher, Vanderbilt, and producer Bradley J. Fischer spent 18 months conducting their own investigation and research into the Zodiac murders. Fincher employed the digital Thomson Viper FilmStream Camera to photograph most of the film and used traditional high-speed film cameras for slow-motion murder sequences.
