Friday the 13th Part 2 (1981)

Friday the 13th Part 2 is a 1981 American slasher film produced and directed by Steve Miner in his directorial debut, written by Ron Kurz, and starring Adrienne King, Amy Steel, and John Furey. It is the sequel to Friday the 13th (1980), and the second installment in the Friday the 13th franchise. King, Betsy Palmer, and Walt Gorney reprise their respective roles from the first film as Alice Hardy, Pamela Voorhees, and Crazy Ralph. Taking place five years after the first film, Friday the 13th Part 2 follows a similar premise, with an unknown stalker killing a group of camp counselors at a training camp near Crystal Lake. The film marks the debut of Jason Voorhees as the series' main antagonist.

Originally, Friday the 13th Part 2 was intended to be an anthology film based on the Friday the 13th superstition. However, after the popularity of the original film's surprise ending, the filmmakers opted to continue the story and mythology surrounding Camp Crystal Lake, a trend that would be repeated in every film in the franchise.

Like the original film, Friday the 13th Part 2 faced opposition from the Motion Picture Association of America, who noted its "accumulative violence" as problematic, resulting in numerous cuts being made to allow an R rating. The film opened theatrically in New York, Los Angeles, and San Francisco on May 1, 1981. Friday the 13th Part 2 received negative reviews, and was less financially successful than the first film, grossing $21.7 million in the U.S. on a budget of $1.25 million. A direct sequel, Friday the 13th Part III, was released one year later.
