Meatcleaver Massacre

Meatcleaver Massacre (also known as 'Hollywood Meatcleaver Massacre') was released in the United States in 1977. Under the 1909 Copyright Act, which governed works published before January 1, 1978, a work required a valid copyright notice (©, year, and name) affixed to all publicly distributed copies. While the film was produced during the 'automatic renewal' era (1964–1977), it still required a valid initial copyright notice or a registration within five years to maintain protection. A search of the U.S. Copyright Office records (both the CCE and the post-1978 online database) fails to show a timely registration for this title under its primary or alternative names. Furthermore, the film is widely documented by film historians and public domain distributors (such as Alpha Video and Sinister Cinema) as having been released without a valid copyright notice on the theatrical prints. Because it was published in the U.S. without notice prior to the 1976 Act taking effect in 1978, and no curative registration was filed, it entered the public domain immediately upon publication. The film is currently treated as an orphan work; the original distributor, Group 1 International, is defunct and no successor in interest has asserted rights for decades. The film's presence in numerous low-budget '50-movie pack' DVD sets, which exclusively utilize public domain material, further confirms its status.
