Sherlock Jr.

The film Sherlock Jr., starring and directed by Buster Keaton, was released in the United States on April 21, 1924. According to the United States copyright law, all works published before January 1, 1929, have entered the public domain. This transition occurred on the expiration of the maximum 95-year term for works that were under copyright protection through those years (specifically those renewed under the 1909 and 1976 Acts). Since Sherlock Jr. was published in 1924, its copyright term expired no later than December 31, 2019. It is now definitively in the public domain in the U.S. regardless of previous renewal status or studio ownership. The addition of a contemporary score or 'HD' restoration mentioned in the title does not extend the copyright of the underlying film, though the specific new score itself might be copyrighted by its composer.
