The following article contains images of explicit Jason kills. And eyeballs. Sensitive readers should look with caution.
Besides being a traditionally unlucky holiday, Friday the 13th is probably most famous for bringing us Jason Vorhees, cinema's most, um, successful psycho killer. He's been copied many times, but nobody has entered into the human psyche in quite the way Jason has.
In honor of his day, lets go over a few facts about the killer king. The franchise has covered three decades, so we could talk trivia forever. But let's just focus on the basics - stuff that every human should know.
He's the second oldest of the famous modern movie psychos
Friday the 13th was released on May 9, 1980, to capitalize on the success of Halloween, which had been released two years earlier (Freddy Krueger began his killing spree in 1984).
Friday the 13th was so popular that 11 more movies were made, including the reboot in 2009.
There are rumors of another movie coming in 2017.
It was not supposed to be a series about Jason
While it was being written, the movie was called A Long Night at Camp Blood. But producer/directer Sean S. Cunningham changed it to Friday the 13th, and to make sure they could claim the name, Cunningham made a quick ad for the movie, even though it wasn't finished being written yet.
After it became a hit, the idea was to make new Friday the 13th movies every year, but have each one be a separate horror film, not connected to each other. However, one of the producers insisted that the sequel be actually about Jason. The rest is history.
Part III was supposed to be the end of Jason
When Part III was made, it was a full 3D film!!!!
Part III was also supposed to finish the Jason saga; he was actually killed at the end. But this one was also so popular that Hollywood couldn't just let him RIP. So he just kind of came back to life for Friday the 13th Part IV: The Final Chapter.
Jason didn't always have his hockey mask
Jason did not acquire his trademark symbol until the beginning of Part III, when he found a hockey mask in a hardware store. So ironically, the movie that gave him his famous look was supposed to be his last movie.
He wasn't the killer in all the movies
True fans know that he wasn't the slasher in either the first movie or in Part V: A New Beginning.
He's killed more people than any other movie villain
Exactly how many people has Jason killed?
Here's where some controversy starts. His victim list depends on what you count as a kill. The kills in Part 1 and Part V clearly don't count. But do dreams and hallucinations count? Possessions? What about virtual reality? Do robots count? Or dogs?
A guy over at the Huffington Post captured every single kill in all the movies and put them all in one convenient video. He marks the ones that he thinks are legit kills, and the ones that aren't. He came up with an official answer of 140 kills. That's far above Freddy and Michael.
