Four men launch an expedition to the jungles of New Guinea to retrieve a valuable opal hidden in a cave during WWII. The jewel is brought to Japan, but turns out to be the egg of an ancient monster called Barugon, that hatches after being exposed to infra-red rays. The creature grows to enormous size and stomps cities; the authorities try different plans to try and defeat the beast, but fail. Gamera, the giant flying turtle, is attracted by Barugon's destructive rainbow energy beam and picks a fight.
Of the Gamera films I have seen thus far (the first four in the series), this is the best, which isn't saying much, I know. Gamera vs. Barugon benefits from being in colour (unlike the original movie), and isn't aimed at kiddies like subsequent efforts (meaning that there is no annoying child to befriend the turtle). The film opens with some enjoyable jungle adventure (superstitious tribesmen, dangerous swamps and deadly scorpions), the monsters are hilariously bad - clearly men in badly designed rubber suits with supporting wires visible throughout - and there's just enough general mayhem and silliness to make the whole thing bearable, especially if really dumb monster movies are your thing.
Not only does Barugon have his ridiculous rainbow beam, but he's also armed with a chameleon-like tongue that sprays a sub-zero vapour to freeze his enemy in their tracks, which makes for a lot of fun (the movie's villain, treacherous treasure hunter Onodera, played by Kôji Fujiyama, meets his fate via the tongue!). Gamera is frozen early on, meaning that he isn't seen for much of the movie, and only shows his scaly face again for the finalé, once he has thawed out, but there's plenty of implausible but entertaining nonsense in the meantime, as the army try to lure Barugon into a lake with a big diamond and reflect the deadly rainbow beams back at the lizard using a giant mirror. Neither ploy defeats Barugon, leaving it up to Gamera to save the day.
4.5/10, rounded up to 5 for the bit where Gamera socks Barugon in the face, resulting in the spillage of gallons of purple blood!
