Although this is the second film in the Fear Street trilogy, it was actually filmed last, after Part One: 1994 and Part Three: 1666.
"Camp Nightwing" is a reference to the setting of the Fear Street book "Lights Out", although the plots are different.
The film borrows heavily from the original Friday the 13th series, especially by having the killer wearing a burlap sack mask, as Jason did in Le Tueur du vendredi (1981).
Camp Rutledge stands in for "Camp Nightwing" and was the major filming location used for Les petites chéries (1980). Both Fear Street: 1978 and Little Darlings have a scene which was filmed at Camp Daniel Morgan, where Vendredi 13, chapitre VI : Jason le mort-vivant (1986) was filmed.
The same newspaper article that Josh (Benjamin Flores Jr.) had on his board about Ruby Lane in Fear Street, partie 1 : 1994 (2021) can be seen in Nurse Lane's diary in this movie.
