Known as Gamera tai Daimajū Jaigā in Japan, or Gamera vs. Giant Devil Beast Jiger, this is the sixth Gamera film. In the U.S., it was released straight to television under the name Gamera vs. Monster X.
The American version contains stock footage from Gamera vs. Guiron and Gamera vs. Barugon to extend the movie’s release time.
As Japan gets ready for Expo ’70 in Osaka, they decide to take a mysterious status called the Devil’s Whistle off an island. Gamera tries to stop them, but they take it anyway. It makes everyone sick and insane that goes near it.
The sound that the Devil’s Whistle makes Jiger go crazy too, so the beast comes down and starts taking out everyone in its way, as well as using its spiked tail to mess up Gamera. It also has a spiky bulbed tail that lays an egg — and eventually a baby Jiger — inside Gamera’s lungs.
That baby looks like a cute version of Jiger, but damn if those little Japanese kids don’t go inside Gamera and kill that infant with static from their walkie-talkies. The scientists then use big speakers to keep Jiger busy while the kids go back inside the giant turtle and jump-start his heart.
In their final battle, Gamera uses telephone poles like earplugs — man, these movies are inventive — and he smashes Juger’s tail, finally making her weak enough to destroy.
Despite the increasingly low budgets and bad effects, Gamera movies remain willing to embrace pure insanity. Isn’t that what we’re all looking for anyway?
