10 Horror Movies That Changed Their Franchise

The first Friday the 13th movie famously features Pamela Voorhees slicing her way through the counsellors of Camp Crystal Lake, with her on a skewed mission of revenge for the death of her young son Jason years prior.

For Jason, he tragically drowned due to the counsellors of the day being too busy having sex and partying. And in that 1980 picture, Mrs. Voorhees' rampage is brutally brought to a halt when she's decapitated by Alice Hardy during the film's closing moments. While Jason would later jump out of the lake to startle Alice, it's implied that this was merely a hallucination.

So, while Friday the 13th establishes that Jason has been dead for years, things clearly changed vastly for the IP when Friday the 13th Part 2 rolled around one year later. Here, we find the adult, hulking form of Jason Voorhees as the one cracking skulls at Camp Crystal Lake - and this would reshape Friday the 13th in a way that has made it one of the most successful franchises in horror history.

It would take until Friday the 13th Part III for Jason to get his iconic hockey mask, but it was Part 2 which first put the character in centre-stage and changed the literal face of the series.
