Enter the Devil

The film was released in the United States in 1972. Under the 1909 Copyright Act, works published between 1964 and 1977 do not require renewal (renewal is automatic); however, they still required a valid copyright notice upon publication and a registration within a reasonable timeframe. A search of the U.S. Copyright Office records and the Catalog of Copyright Entries (CCE) reveals no registration for this title under the production company 'Sunset Cove' or the title 'Enter the Devil' around its release. More importantly, the film has historically been treated as public domain by the home video industry, appearing in numerous '50 Movie Pack' collections from distributors like Mill Creek Entertainment and Alpha Video, who specialize in public domain content. The absence of a copyright notice on surviving prints or a timely registration, combined with its ubiquitous presence in public domain catalogs, indicates it failed to secure or maintain US copyright protection.
