Beyond the Door (film series)

Beyond the Door is a horror film series that consists of three originally unconnected films that were retitled to be part of a supernatural franchise for the American and English speaking markets, and one direct sequel to the 1974 original. Several loose connections between the first three films are that all three were Italian productions, Ovidio G. Assonitis produced parts I and III, child actor David Colin Jr. starred in Parts I and II (but playing different characters).
