- Both the American theatrical release and the Sandy Frank version havent been re-released on official DVD & Blu-ray releases.note Even when Shout! Factory got the rights to release the Gamera films on DVD they were unsuccessful in licensing the the original American cut as the company refused to let it be licensed and released again until 2020 when Arrow Video announced it would be included on their box set.
- An incomplete 35mm print of the American cut was discovered, digitally restored and made available for purchase on Amazon Prime in 2017 by Legend Films, Inc.
- The International dubbed version, however, has yet to get an official release outside the Mystery Science Theater version.
