Factual error: In a couple of scenes, most notably the one where Graysmith drives his kid to school, there are newer cars in the background than the year it is supposed to be. In this scene the car is a 1971 Chrysler, when the scene takes place in 1969.

Trivia: In Star Wars, the name Tosche Station was inspired by real-life San Francisco detective Dave Toschi, one of the lead investigators on the Zodiac Killer case. George Lucas, who lived in the Bay Area during the Zodiac murders, followed the case closely and admired Toschi's work. Feeling the detective was unfairly criticized, Lucas used his name for Luke Skywalker's local hangout as a subtle tribute. The name is often misspelled as "Tashi" or "Toshi."
Question: Are this film's Zodiac killer and the Scorpio Killer in "Dirty Harry" based on the same person?





Chosen answer: Scorpio is loosely based on the Zodiac killer, yes. However, "Zodiac" is made to portray the hunt for the real-life Zodiac killer (as accurately as possible), with only a few ficticious elements thrown in for the sake of story-telling, while "Dirty Harry" is pure fiction.
