Creature of the Walking Dead

This film was originally produced in Mexico as 'La Marca del Muerto' (1961). It was imported to the US and significantly altered (re-edited with new footage) by producer Jerry Warren for release in 1965. Under the copyright laws of the time, foreign films distributed in the US required a valid US copyright notice to maintain protection; however, Warren was notorious for failing to include proper copyright notices on his productions or failing to register them with the US Copyright Office. No US copyright registration for 'Creature of the Walking Dead' exists in the online Copyright Office records or the Catalog of Copyright Entries (CCE) for the mid-1960s. Furthermore, as a Mexican production released in the US without notice, it might theoretically be a candidate for URAA restoration. However, the film is widely documented in public domain filmographies (such as the Film Superlist) and has been distributed for decades by numerous budget/PD labels including Sinister Cinema, Alpha Video, and Retromedia without legal challenge. The absence of a registration during the automatic-renewal era (1964+) combined with a lack of copyright notice on the prints as distributed in the US places it firmly in the public domain category.
