Godzilla vs. Matt Helm

Godzilla vs. Mecha-Godzilla (1974): The penultimate Godzillaverse movie in the original Toho Studios run demonstrates that old adage about history beginning as tragedy, returning as comedy, and ending in farce. 

Aliens send a giant robot Godzilla to conquer the Earth. Godzilla teams up with kaiju King Caesar, some scientists, and Interpol to save the world. King Caesar is easily the worst kaiju Toho ever created, a sort of cross between a lizard, a Muppet, and a team mascot. Godzilla demonstrates another new power, generating a massive magnetic field. Well, why not? Lightly recommended.

Terror of Mecha-Godzilla (1975): Original Godzilla director Ishiro Honda returns for this final entry in the original Toho series. That makes for a decent finalé, with Godzilla even strolling off into the sunset at the end, sort of. There's a bit too much Interpol vs. the Space Aliens action in this one which may have contributed to its series-ending low box office. 

Along with a resurrected Mecha-Godzilla, the undersea-dwelling Titanosaurus also battles Godzilla under the control of the aliens and a misanthropic human scientist and his alien-resurrected cyborg daughter. This last leads to a scientist-hero telling the woman, "I don't care if you're a cyborg, I still love you." Shakespeare, eat your heart out! Lightly recommended.

The Wrecking Crew (Matt Helm 4) (1968): Sharon Tate is pretty much the only reason to watch this unfunny, boring yet fascinating mess -- fascinating mainly because Mike Myers drew a lot of inspiration for the Austin Powers movies from the Matt Helm series, including Dean Martin's cover job as a fashion photographer. When someone says movies today are bad and overly parts of serials, make them watch this. And it's purportedly better than Matt Helms 2, 3, 5, and the TV series!!! Not recommended.
