While the film tells the story of the making of Dolemite (1975), the car chase, the Cadillac exploding, and the sex scene are from the sequel, The Human Tornado (1976). The scenes are intentionally included as a nod to Moore's later film.
While filming the sex scene, Rudy Ray Moore says the line "Put your weight on it." While this line is never said in Dolemite (1975) or The Human Tornado (1976) (the film the actual scene is from), it's said 24 times in Moore's fourth film, Disco Godfather (1979). It's included here as an "inside joke."
When Dolemite (1975) is shown in theaters, it is heavily edited and intentionally interspersed with scenes from The Human Tornado (1976).
