6 Real Serial Killers That Defined The Horror Film Genre

2. The Zodiac Killer

Potentially the most famous killer that nobody knows, bar Jack the Ripper, The Zodiac Killer has gained notoriety for his claimed murders of 37 people, of which 7 have been definitively confirmed between 1968 - 1969.

That really means nothing however, as cryptograms from the case are still unsolved now - meaning police were dealing with a man that likely was the perpetrator of many more crimes than they could attribute to him.

Taunting newspapers and police forces alike, The Zodiac Killer consistently sent misspelled and cryptic messages demanding publicity for his crimes - threatening to kill more if he didn’t get his way.

Popularised by David Fincher’s Zodiac in 2007, a reconstructed version of the events that occured in the late 60s, there are at least 11 other films have been made about the unsolvable case.

Movies pour over case files, letters, old evidence and hypothetical situations in various levels of extremity, but none have come close to solving the crime - though many have their theories.
