The most notorious serial killer of our time... remains at large. The Zodiac is the work of Alexander Bulkley, who also wrote the script with his brother Kelley Bulkley. The film features Justin Chambers, Robin Tunney, Rory Culkin, Philip Baker Hall, Brad Henke, Marty Lindsey, Rex Linn and William Mapother. Michael Suby composed the music, and Denis Maloney was responsible for the cinematography. The story is based on actual events concerning a serial killer known as The Zodiac who terrorized the San Francisco Bay Area during the late 1960s; he was never apprehended. There’s been considerable criticism of Bulkley's film, which seems reasonable considering it doesn't offer an exhaustive look at the case itself or function as a truly frightening serial killer movie. That perception isn’t helped by David Fincher’s detailed version from 2007. Still, The Zodiac does have some merit, even if recommending it is difficult to do with certainty. The Bulkley brothers decide to concentrate mainly on one police officer and his family and how they are profoundly impacted by the Zodiac case. This involves Detective Matt Parish (Chambers) facing increasing pressure both at work, where superiors want results, and at home, where his wife Laura (Tunney) becomes increasingly worried and frustrated, and their young son Johnny (Culkin) develops an unhealthy interest in the investigation. The director creates a convincing period setting while skillfully weaving a sense of paranoia throughout the story, which must have permeated the Bay Area as The Zodiac committed his crimes. The killer’s face is appropriately never shown, although we do see perspectives from the killer and brief glimpses from a distance or from behind him. Interestingly, there's a connection between The Zodiac and young Johnny as they each pursue their own activities. The color palettes used at different points in the story are well-considered, giving the film a documentary feel for outdoor scenes and a saturated neo-noir atmosphere for interiors. A simplicity to the production really serves the subject matter. The acting is acceptable; Tunney does a good job with her role, and Suby's score creates an unsettling mood. This isn’t something that fans of gore or Zodiac experts should actively look for, but it remains a better-than-average film that manages to transcend its limited budget. 6/10
