Isle of Forgotten Sins

The film was released in 1943 by the 'Poverty Row' studio PRC. Under the Copyright Act of 1909, works published between 1928 and 1963 required a copyright renewal filing during the 28th year of the original term to maintain protection. If not renewed, the work entered the public domain. A search of the Stanford Copyright Renewal Database and the Library of Congress Catalog of Copyright Entries (CCE) indicates that no renewal was filed for 'Isle of Forgotten Sins' (originally registered under LU4051 and LP12246). Given that PRC was a smaller studio that eventually dissolved and sold its library to various television syndicators (like Eagle-Lion and later United Artists), many of its titles fell into the public domain through administrative oversight. This title is widely cited in public domain reference works, including Hurst and Baer's 'Film Superlist,' and is legally distributed by numerous public domain specializes such as Alpha Video and Sinister Cinema without interference. The absence of a renewal record for a 1943 US production definitively places it in the public domain.
