You can’t mention Friday the 13th without thinking of Jason Voorhees, the legendary killer whose origins began at Camp Crystal Lake 35 years ago. The first film in the franchise opened on May 9th, 1980 and told the story of a group of camp counselors who were being stalked and killed during the re-opening of Camp Crystal Lake. Of course, the killer turned out to be Pamela Voohees (sorry, statute of limitations on spoilers expired for this film), who was seeking revenge after her son, Jason, drowned at camp years earlier. Once Pamela was killed, Jason emerged from the lake to pick up right where she left off at Camp Crystal Lake. Through the years, Jason Voohees has been to many other places like Manhattan, outer space, and even hell. While his heart will always be at Camp, let’s take a look through all 12 Friday the 13th films to learn more about the machete-weilding killer.
