Godzilla fights a Gargantua(s)

Not much is known about this film except for that Godzilla would be fighting atleast one Gargantua, and that it would follow the script for the American version of the film, thus ignoring the Gargantua's connection with Frankenstien. This project never got beyond the proposal stage. Henry Saperstein of UPA liked the movie War of the Gargantuas (1966) and wanted to put up $6 million for a movie that featured Godzilla fighting a Gargantua. Unfortunately the project never got very far and it is unknown if Godzilla would have fought Gaira, Sanda, or possibly a new creature born from Gargantua cells.
