The Cruel Tower

The Cruel Tower was originally released in the United States on October 28, 1956, and registered for copyright by Lindsley Parsons Productions, Inc. (LP8546, October 22, 1956). Under the Copyright Act of 1909, works registered between 1928 and 1963 required a formal renewal filing with the U.S. Copyright Office during the 28th year of the first term to remain protected. A thorough search of the Stanford Copyright Renewal Database and the Library of Congress Catalog of Copyright Entries (CCE) reveals no record of a renewal for this motion picture. For a 1956 registration, the renewal window would have been in 1983 or 1984. The absence of a renewal filing caused the work to fall into the public domain at the expiration of its initial 28-year term in 1984. This film is frequently cited in public domain industry guides, such as the Film Superlist: Motion Pictures in the U.S. Public Domain (1950–1959), which confirms the lack of renewal. It is currently distributed by several public domain home video labels and is available on archive platforms without copyright challenge.
