The King of the Monsters wrote: 1984-89 and 1991-95 are technically the same Godzilla, because when the Futurians placed the Godzillasaurus in the ocean, it was exposed to radiation in the 1970s and became Godzilla, then attacked Tokyo in 1984. In 1991, it was just exposed to more radiation and grew to 100 meters. In reality, the Futurians only wrote the future they were trying to prevent.

The 1970's were never mentioned in the film.
