The Monster That Challenged the World

This film was released in 1957 and falls under the US copyright requirement for renewal after 28 years. A search of the Stanford Copyright Renewal Database and the Library of Congress CCE confirms that the copyright was successfully renewed. The original registration was LP8463 (May 17, 1957) by Gramercy Pictures, Inc. The renewal was filed on February 4, 1985, under renewal number RE236316 by United Artists Corp, the successor in interest. As the renewal was timely filed within the 28th year, the film is protected for a full 95-year term from its 1957 release date. The film is currently managed by Metro-Goldwyn-Mayer (MGM) through their acquisition of the United Artists library. It has seen consistent commercial exploitation, including high-definition Blu-ray releases by Kino Lorber (2015) and inclusion in various licensed streaming platforms, which further confirms an active chain of title and enforcement of copyright.
