Attack of the Spider Woman

The film 'Attack of the Spider Woman' (1968), also known by its original Spanish title 'La mujer murcielago' (The Bat Woman), is a Mexican production. Because it was released in the 1964–1977 window, its US copyright status is complex. It was distributed in the US by K. Gordon Murray and Trans-International Films in a dubbed version. Under the rules for this era, foreign films only attained US copyright if published with a valid US copyright notice or registered with the US Copyright Office. No US copyright registration for this film appears in the Catalog of Copyright Entries (CCE) or the US Copyright Office online database. While the URAA (1996) restored copyrights to many foreign works that were in the public domain for technicalities, restoration only applied if the film was still under copyright in its source country (Mexico) on January 1, 1996. While Mexican law generally provides long-term protection, there is no evidence that a Notice of Intent to Enforce (NIE) was ever filed with the US Copyright Office to assert these rights against reliance parties. The film is frequently included in '50-movie pack' public domain collections by distributors like Mill Creek and Alpha Video, and it is widely available on archive.org without takedown notices. Because of the lack of a primary US registration and its consistent treatment as public domain by budget distributors, but the theoretical possibility of URAA protection, the status is marked as uncertain.
