What about Friday the 13th?

The first Friday the 13th film was released in 1980. Since then, there has been 9 sequels, 1 hybrid film (Freddy Vs. Jason) and 1 remake/re-imagining that came out most recently (2009). So, in total there are 12 "Jason" films.

About half of the films actually came out on Friday the 13th as a marketing ploy. Friday the 13th has one of largest cult followings that makes the franchise still popular today. Every film except for "Jason Goes to Hell" has been released theatrically.
