The controversial theory spread throughout the fandom like wildfire. Could Godzilla vs. Biollante and Seinfeld take place within the same canon? Sure it was possible, but we needed more evidence. Thus began the massive search for any clues or connections. Fans scoured the unending backwaters of the internet until, at long last, a few screenshots emerged. Thesetwo were uncovered by @spacehunter-m and @raffleupagus respectively:
This was it: the proof we needed! Kazuki Omori originally wrote and directed Godzilla vs. Biollante as an episode of the then upcoming TV series Seinfeld! It was originally going to be released by New World Pictures as a direct sequel to their production of Godzilla 1985, but the American distribution rights were sold to HBO after Shogo Tomiyama lost a poker game with his executive friends. By the time it was going to be released in the states, Seinfeld was then under the jurisdiction of NBC. After several weeks of intense business dealings, NBC, Toho, and HBO failed to come to an agreement of who controlled what assets of the film. Ultimately, Toho decided to release an edited version of the film that removed all mentions of the characters and branding of Seinfeld in 1989. Three years later, HBO released an English dub of that version, and the original Seinfeld-filled edit of Godzilla vs. Biollante was lost to time.
This shocking news took the fandom by storm. Many of us pestered Jerry Seinfeld himself on twitter about the events. When asked if it’s events were still canon within the Seinfeld universe, he replied with a single, yet earth-shattering, “Yes.”
So there you have it! The classic Heisei kaiju film Godzilla vs. Biollante is actually an episode of the beloved NBC sitcom Seinfeld. Hope that answered your questions @herr-kroenen and anon!
