The Hound of the Baskervilles

The film identified is the 1939 20th Century-Fox production starring Basil Rathbone, which is the only major English-language version released within the ±2 year window of the user's 1937 hint (a German version, 'Der Hund von Baskerville', was released in 1937, but the 1939 Hollywood version is the canonical US production of that era). As a US work published between 1928 and 1963, its copyright status depends on a timely renewal in the 28th year. Registration and renewal records confirm the film is protected. The original registration was filed on March 31, 1939 (LP8987). A renewal was filed with the US Copyright Office by 20th Century-Fox Film Corp. on April 20, 1966 (R384501). The Stanford Copyright Renewal Database and the CCE confirm this renewal. Under the 1976 Copyright Act and subsequent extensions (Sonny Bono Act), the copyright was extended to 95 years from the publication date, meaning it will not enter the US public domain until January 1, 2035. Note: generated without live web grounding (the grounded research engine was unavailable). Verify the cited sources independently before relying on this determination.
