Las mil noches y una noche

The most prominent film by this title is the 1958 Mexican musical fantasy directed by Fernando Palacios. As a foreign production from 1958, its US copyright status is determined by whether it was published in the US with a valid copyright notice and subsequently renewed, or if it qualified for restoration under the 1994 Uruguay Round Agreements Act (URAA). No US copyright registration or renewal was found in the Stanford Renewal Database or the Library of Congress Catalog of Copyright Entries for a film under this specific title, suggesting it may never have secured a formal US copyright during its initial 28-year term. Under the URAA, the film's US copyright would have been automatically restored on January 1, 1996, if it was still protected by copyright in its source country (Mexico) on that date. While Mexico has long copyright terms (currently life + 100 years), there is no evidence in the US Copyright Office's 'Notices of Intent to Enforce' (NIE) records that the rightsholders filed to protect this specific work against reliance parties. Because I cannot confirm a contemporaneous US publication with notice nor verify the specific status of its Mexican copyright at the 1996 restoration window without access to Mexican domestic records, the status must be classified as uncertain. The film is not widely exploited by major US distributors today, though it remains a known work of the Mexican 'Golden Age' period.
