(Gojira-Minira-Gabara: Oru Kaiju Daishingeki)
Godzilla's Revenge is mostly centred around Minya instead of Godzilla, a focus that considerably belies the ferocity the title seems to suggest. Minya is only there to take pratfalls and give life lessons to the kid. There is much silly nonsense with Minya only able to blow smoke rings instead of radioactive fire and with the kid having to drop a rock on his tail to make him unleash fire properly. The films lowest point is having Minya talk with a dubbed voice. There is also a cartoonishly silly score and sound effects. Special effects man Eiji Tsuburaya was ill throughout shooting and died a few months after the films release as a result, the effects scenes were filled out using scenes taken from Godzilla vs the Sea Monster (1966) and Son of Godzilla.
