was released on DVD in North America. This version includes the original Japanese theatrical version, the American version (running at 84 minutes), and the international version with the alternate giant octopus ending (running at 93 minutes). All three versions were presented in widescreen. The international version (titled Frankenstein vs. the Giant Devilfish) features an audio commentary by Sadamasa Arikawa, the film's special effects photographer. Disc two features two Japanese trailers, deleted scenes and a photo gallery, which was provided by Ed Godziszewski (editor of Japanese Giants and author of The Illustrated Encyclopedia of Godzilla). In November 2017, Toho released the film on Blu-ray in Japan. This release also includes an HD remaster of the international version. In September 2022, The Criterion Collection announced to have acquired the Japanese version to stream on their site the Criterion Channel. Sequel The following year, Toho released a sequel titled The War of the Gargantuas, also co-produced with UPA. In the film, pieces of Frankenstein's cells mutate into two giant humanoid monsters: Sanda (the Brown Gargantua) and Gaira (the Green Gargantua). The former is a benevolent and peace-loving creature, while the latter is murderous and savage. Apart from a reference to a severed hand, UPA obscured all references to Frankenstein in the American version and the names of the monsters were changed to the Brown Gargantua and the Green Gargantua. Gaira and Sanda would later appear in two of Toho's tokusatsu series, Ike! Godman and Ike! Greenman, before remaining absent for over 40 years, with Gaira making his latest appearance in a 2008 Go! Godman special.
