The Bamboo Prison

The film was registered for copyright by Columbia Pictures Corp. on December 1, 1954, under registration number LP4321. Under the Copyright Act of 1909, works registered between 1928 and 1963 required a manual renewal filing with the US Copyright Office during the 28th year of their first term to maintain protection. For a 1954 release, the renewal window was open in 1981 or 1982. A search of the Stanford Copyright Renewal Database and the US Copyright Office online catalog (which covers renewals filed from 1978 onward) shows no renewal record for this title or registration number. While Columbia Pictures renewed many of its 1954 titles (such as 'The Caine Mutiny' and 'On the Waterfront'), 'The Bamboo Prison' was notably omitted from these filings. Consequently, the work fell into the public domain upon the expiration of its first 28-year term at the end of 1982. The film is widely recognized as being in the public domain by researchers and is frequently distributed by secondary 'PD' labels and hosted on the Internet Archive without takedowns from Sony/Columbia, further confirming its status.
