Wells' novella The Invisible Man.[3] Gastaldi noted that the starting point for the film's development was comic books and director Mino Loy's desire to develop a film with special effects involving partially reflecting mirrors.[3] It was directed by Mino Loy, whose real name was Guglielmo Loy Donà. It was his third last film as a director.[3]
Paolo Gozlino [it] acted in the film under the name Paul Stevens.[4] Gozlino was a well-known dancer and choreographer in Italy mostly due to his appears in many television shows.[4]
