Brides of Blood

Brides of Blood is a 1968 Filipino horror film co-produced by Hemisphere Pictures (a US-based company) and distributed in the US. Under the copyright laws applicable to the 1964–1977 era, works were protected only if published with a valid US copyright notice. While the film was produced by a US/Filipino partnership, it is widely documented by film historians and PD distributors (such as Alpha Video and Retromedia) as having been released in the United States without a valid copyright notice on the film prints, causing it to fall into the public domain immediately upon publication. A search of the US Copyright Office records and the Stanford Renewal Database shows no original registration or subsequent renewal that would have 'cured' a notice defect. Furthermore, while the URAA (1996) restored copyright to many foreign works, it generally does not apply to works that were co-produced by US entities or were published simultaneously in the US and a foreign country without notice, as they are treated as US works for notice purposes. The film has been a staple of public domain 'horror pack' DVD collections for decades without legal challenge from the now-defunct Hemisphere Pictures or its successors.
