Director David Fincher returns with an arresting take on one of American historys most notorious series of unsolved murders. Jake Gyllenhaal plays Robert Graysmith, a cartoon artist for the San Francisco Chronicle
who researched and hunted the Zodiac Killer in the 70s. The killer was never caught, and the film spends a decent amount of time on Arthur Leigh Allen, the prime (and now dead) suspect. Robert Downey Jr. is his usual excellent self as Paul Avery, the Chronicle
reporter who wrote about the Zodiac. Mark Ruffalo is also terrific as Inspector David Toschi, who chased the killer for years but came up empty. The film is long, and it doesnt have the usual whodunit payoff. It also manages to be terrifying at times, something Fincher does well. It leaves you feeling a little sick that the guy could still be out there.
