Before Camp Blood came out in the US, there were plans for a sequel.
When the girl tells the story about the clown, the name of the victim is said to be Mary Lou Maloney. This is the same name as a character in Hello Mary Lou: Prom Night 2. Camp Blood cast member Courtney Taylor starred in Prom Night III: The Last Kiss.
The film's title is taken from the Friday the 13th series. The working title for the first Friday the 13th film was A Long Night at Camp Blood. In both the first film and Friday the 13th: Part 2 (1981), characters refer to Camp Crystal Lake as Camp Blood on several occasions.
The name Victor Cunningham is a nod to Friday The 13th (1980) writer/creator Victor Miller and original F13 director Sean Cunningham.
