Massimo Pupillo(1929-1999)

After completing the direction of his horror film 5 tombe per un medium (1965), he was unsatisfied with the final result, and allowed the film's producer, Ralph Zucker, to take the director's credit instead. This has led people to confuse Pupillo and Zucker for one another, and when Zucker died in 1982, some thought that Pupillo had died, which is incorrect.
