Invasion of the Saucer Men

Under the Copyright Act of 1909, works published between 1928 and 1963 required a renewal filing with the US Copyright Office during the 28th year of the first term to maintain protection. 'Invasion of the Saucer Men' was registered by Malibu Productions (LP8506) following its June 1957 release. The copyright would have been eligible for renewal in 1985. A search of the Stanford Copyright Renewal Database, the U Penn online Catalog of Copyright Entries (CCE), and David Pierce’s 'Motion Picture Copyrights and Renewals 1950–1959' confirms that no renewal was filed for this title. Consequently, the film entered the public domain in the United States on January 1, 1986. This status is further evidenced by the film's widespread availability in public domain collections from distributors like Alpha Video and its presence on Archive.org without takedown, distinguishing it from other AIP properties that were successfully renewed (such as 'The Amazing Colossal Man'). Note: generated without live web grounding (the grounded research engine was unavailable). Verify the cited sources independently before relying on this determination.
