Bloodthirsty Butchers

The film 'Bloodthirsty Butchers' (also known as 'The Bloodthirsty Butchers') was released in the United States in January 1970. Under the copyright laws in effect at that time (the 1909 Act as amended), works published between 1964 and 1977 were granted automatic renewal. However, the film still required a valid copyright notice upon its first US publication to secure federal protection. A search of the United States Copyright Office records (CCE and online database) and the Stanford Copyright Renewal Database shows no original registration for this title under Constitution Films or director Andy Milligan. Crucially, the film was widely distributed in the 1980s and 1990s by budget and public domain labels such as Alpha Video, Something Weird Video, and Midnight Video, typically signaling a lack of valid copyright notice on the original prints. Because there is no record of a contemporary registration to cure the lack of notice, and the film has been treated as public domain by specialized distributors for decades without legal challenge from the now-defunct Constitution Films or Milligan's estate, it is classified as public domain due to failure to comply with notice requirements.
