The listing of 20th-Century Fox movie titles should not have had "The" as the first word of Il fantasma del palcoscenico (1974), as this was only four words in its title.
The movie's ending credits listing for Universal Pictures' contributions should have included 1931 versions of Dracula (1931) and Frankenstein (1931).
The ending credits of movie titles and their involved companies has the copyright year of Zombi (1978) was 1978 (Italian production), not 1968, which was the correct year for its predecessor La notte dei morti viventi (1968).
When mentioning Non aprite quella porta (1974), Donald Pleasence says the movie was inspired by serial killer Ed Gein, pronouncing this Ed Gine, when actually Gein's name is pronounced Geen.
