The film is loosely inspired on the now defunct Action Park in Vernon, New Jersey that first opened in 1979. The park was considered by many to be one of the most dangerous theme parks in the United States. At least six people were known to have died as a result of incidents that occurred within the original park. The park closed in 1996 and later reopened, under new ownership, as Mountain Creek. After yet another ownership change, the park briefly changed its name back to Action Park for the 2014 and 2015 seasons before reverting back to Mountain Creek in 2016, in order to disassociate itself from the former park's infamous reputation. The real park is the subject of the documentary
Class Action Park (2020).
