After making these horror films, Pupillo stated that he originally made them to get out of making documentary films and enter the commercial film market.[3] After making La vendetta di Lady Morgan he declared he was finished with making horror films with his following directorial work becoming scarce.[3] His follow-ups included the WesternDjango Kills Softly released in 1967 and the mondo filmLove: The Great Unknown.[3] Pupillo also wrote a few mondo films prior to directing including Primitive Love and Sweden: Heaven and Hell which were both directed by Luigi Scattini and Taboos of the World by Romolo Marcellini.[3]
Pupillo later described himself as "disgusted" by the type of cinema he was making and primarily worked in television during the 1970s.[3] His last feature film was Sa Jana which was shot in Sardinia.[3] According to Merrill Aldighieri and Lucas Balbo's documentary Mondo Pupillo - Une conversation avec Massimo Pupillo, it is likely that Pupillo died on December 29, 1999, but no evidence has been found to confirm this.[3]
