Ghidorah, the Three-Headed Monster

This film, originally released in Japan as 'San Daikajū: Chikyū Saimitsu no Kessen' in December 1964, was distributed in the United States by Continental Distributing in 1965. Under the 1992 Copyright Renewal Act, works published between 1964 and 1977 are granted automatic renewal, meaning a manual renewal filing in the 28th year was not required to maintain US copyright. Furthermore, as a Japanese production, the film is subject to the Uruguay Round Agreements Act (URAA). Because the work was still under copyright in its source country (Japan) on the URAA date of January 1, 1996, its US copyright was automatically restored or reinforced regardless of any previous US formalities like notice defects. The film is currently managed and actively licensed by Toho Co., Ltd., and is widely available on reputable streaming services and home video through authorized distributors like Janus Films (The Criterion Collection), which confirms the copyright remains active and enforceable. Note: generated without live web grounding (the grounded research engine was unavailable). Verify the cited sources independently before relying on this determination.
