Robert Graysmith is a cartoonist who works for the San Francisco Chronicle. His quirky ways irritate Paul Avery, a reporter whose drinking gets in the way of doing his job. The two become friends thanks to a shared interest: the Zodiac killer. Graysmith steadily becomes obsessed with the case, as Avery's life spirals into drunken oblivion. Graysmith's amateur sleuthing puts him onto the path of David Toschi, a police inspector who has thus far failed to catch his man; Sherwood Morrill, a handwriting expert; Linda del Buono, a convict who knew one of the Zodiac's victims; and others. Graysmith's job, his wife and his children all become unimportant next to the one thing that really matters: catching the Zodiac.

Shane Salerno optioned the Robert Graysmith book "Zodiac" when he was just nineteen years old and developed it with Graysmith for several years before selling it to Disney's Touchstone Pictures in a seven-figure deal. Salerno wrote several drafts of the screenplay before multiple administration changes at Touchstone derailed the project.

I've been thinking...


Paul Avery:
Oh God, save us all.

Anachronisms: The overhead shots of the San Francisco taxi show Bus Only lanes with a diamond symbol. While there were Bus Only lanes at the time, the diamond symbol was not used until many years later.
