The Diabolical Dr. Z

Originally titled 'Miss Muerte' (1965), this film was released in the US as 'The Diabolical Dr. Z' in 1966. Because it is a foreign production from the 1964–1977 era, US copyright would depend on either a valid US copyright notice on release prints or URAA restoration (17 USC § 104A). While the film is a cult classic by Jesús Franco, there is no evidence of a formal US copyright registration in the Library of Congress CCE or the online COcatalog. Under the URAA, the film would be restored if it was still under copyright in its source countries (Spain/France) on January 1, 1996. However, without concrete evidence of a US registration or a documented URAA filing (Notice of Intent to Enforce), its US status remains technically uncertain. The film frequently appears on public domain lists and in low-budget collections, though boutique labels like Kino Lorber currently license it, suggesting a potential active rightsholder in Europe whose US standing is ambiguous. Note: generated without live web grounding (the grounded research engine was unavailable). Verify the cited sources independently before relying on this determination.
