Set directly after the events of the previous film, Friday the 13th Part III is again about a group of friends staying near Crystal Lake who encounter Jason Voorhees as he embarks upon another killing spree. Shot in 3D the film has a less sleazy tone than its predecessors although the formula remains the same. The set pieces and death scenes are more elaborate and less clinical, taking advantage of the 3D picture format. The film marks the first appearance of Jason's signature hockey mask, which subsequently became a trademark of both the character and the franchise. Originally conceived to be an end to the series of films, Friday the 13th Part III performed extremely well at the box office, earning $36.7 million on a budget of $2.2 million. As a result, the franchise was given a stay of execution and a further sequel was commissioned.

Originally, Friday the 13th Part 2 was intended to be an anthology film based on the superstition associated with the date. However, after the popularity of the original film's surprise ending, the producers opted to continue the story and mythology surrounding Camp Crystal Lake. This eventually became the parameters which all future films would broadly work within. Friday the 13th Part 2 is a more polished production than the first movie, benefitting from twice the budget of the original. The quick turnaround meant that Paramount Pictures could continue to capitalise on the popularity of the slasher genre. However, there was growing social pushback against these types of films, from Christian lobby groups and other “concerned parties”. Hence, Friday the 13th Part 2 ran into problems with the MPAA ratings board and cuts were imposed. Something that would continuously plague the franchise over the years.
