The movie was strongly influenced by Belphégor ou le Fantôme du Louvre, a 1965 french serial. The writer Giuseppe Ferrara was so fascinated by it that decide to write some sort of tribute movie. With the help of Sergio Ingrao and Riccardo Scuto it was changed in a original story, but with strong references to the french serial.
A group of Youtubers, Geckoz Clan, formed by the cousins of Giuseppe Ferrara had released a parody of "L'Ombra di Baal" called "L'Ombra di Amon".
