Orgy of the Dead

The film was released in 1965, placing it within the 1964–1977 window where copyright protection was automatic for 28 years under the Copyright Act of 1909. However, for films from this era, the validity of copyright depended on the presence of a proper copyright notice on the release prints (17 U.S.C. § 401). Extensive research by film scholars and public domain specialists, including David Pierce and the Hollywood Film Archive (Film Superlist), has identified 'Orgy of the Dead' as having been published without a valid copyright notice. Furthermore, no original registration was filed with the U.S. Copyright Office at the time of release to 'cure' the lack of notice, nor was a renewal necessary because the 1992 Amendment only automatically renewed works that were already in their first term of valid copyright. Because the film entered the public domain immediately upon publication due to the notice defect, it remains in the public domain today. It is widely included in public domain catalogs such as Alpha Video and is available on archive.org without copyright challenges.
