Based on the true story of the serial killer who terrorized San Francisco in the late 1960s, this engrossing mystery stars Jake Gyllenhaal as a San Francisco Chronicle cartoonist who becomes obsessed with the manhunt; Mark Ruffalo and Robert Downey Jr. are the police inspector and reporter, respectively, on the same mission. With a meticulous attention to detail (and plenty of foreboding atmosphere courtesy of Harris Savides’ cinematography), this may be the last word on a case that remains officially unsolved.
