The Mystery of Deadman's Isle

The Mystery of Deadman's Isle (also stylized as 'The Mystery of Dead Man's Isle') is a three-reel American silent drama released in June 1915. It was produced by the American branch of Gaumont and distributed through the Mutual Film Corporation. The film was directed by Giles R. Warren. According to the US Copyright Act, all works published or registered for copyright in the United States before January 1, 1928, have entered the public domain. This applies regardless of whether the copyright was renewed, as the maximum possible term of 95 years from publication has expired for all works from this era. As a 1915 release, the film's copyright expired no later than 1990 (the end of the 75-year term under the 1976 Act for works published before 1978). Records in the Catalog of Copyright Entries (CCE) confirm that films of this era were subject to the 1909 Copyright Act, which provided an initial 28-year term and a single renewal term. Since the film is over 100 years old, it is definitively in the public domain in the United States. No further search for renewal records is required for this publication date.
