"Even if you're a cyborg, Katsura, I still love you!"
~ Akira Ichinose
"What do your bullets matter? Hahaha!!!"
~ Commander Mugan
The final film of the original series, also known as the Showa Era of the Godzilla series (while Destroy All Monsters is the last film chronologically), and directly taking place after the previous year's Godzilla vs. Mechagodzilla. This is the final Godzilla film directed by the legendary Ishiro Honda, and is called Mekagojira no Gyakushū (Counterattack of Mechagodzilla) in Japan. Also goes under the title "The Terror Of Godzilla" in it's initial U.S release.The movie was not well received when it was released, and Toho would not produce another Godzilla movie until the king's 30th anniversary in 1984. The film was one of only two Godzilla films to have less than a million tickets sold. It would remain the least attended Godzilla film until Godzilla vs. Megaguirus in 2000. This would also be the last Godzilla film to be directed by Ishiro Honda. The music was composed by Akira Ifukube, and the special effects were directed by Teruyoshi Nakano. The film was produced by Tomoyuki Tanaka.
This film contains examples of the following:
Arbitrary Skepticism: The scientists don't believe Mafune's theory of a dinosaur living near Japan despite the fact that two Godzillas had already come to Japan before doing such (The first was a villain while the other in 1955 had a Heel-Face Turn, serving as Japan's protector).
Armor Is Useless: Averted. Mechagodzilla is immune to pretty much everything under the sun, and takes multiple hits from Godzilla's atomic ray without slowing down. He's only destroyed after Katsura, who has Mechagodzilla's controls inside of her, kills herself.
Big Damn Heroes: Godzilla shows up just in time to save some kids from getting squashed by Titanosaurus.
Possibly subverted because it's a major "Or does he?" moment.
Blow You Away: Titanosaurus can use his tail like a fan, easily knocking Godzilla off his feet.
Darker and Edgier: Compared to the previous film and the other two before it, TOMG is the darkest Godzilla film in the Showa series since Godzilla vs. Hedorah. Sure, it's not as dark as the first film, but there are definitely clouds hanging overhead. Mechagodzilla's paint scheme even seems to lampshade this, as it is a darker grey compared to the bright silver of the previous film.
Determinator: It doesn't matter how much firepower Mechagodzilla has, or how powerful Titanosaurus' tail fan is. Godzilla just keeps coming.
Gentle Giant: Titanosaurus. He is only violent when he's being mind-controlled.
Giant Equals Invincible: Titanosaurus and Mechagodzilla are both pretty much immune to bullets and mortars. Titanosaurus is still vulnerable to sonic waves and Godzilla's atomic ray, after receiving multiple hits from it.
Heroic Sacrifice: After Ichinose refuses to kill her, Katsura takes the laser gun and shoots herself, destroying Mechagodzilla's controls.
Immune to Bullets: Mugan would like to believe this about himself, and he may be right, but he and his escape ships are definitely not immune to Godzilla's atomic ray.
Improbable Aiming Skills: Apparently, one of the humans who was aiming a sonic emitter onto Titansaurus somehow aim at his neck.
I Cannot Self-Terminate: Subverted. Katsura thinks that she can't, so she asks Ichinose to kill her. He refuses, so she takes the gun and destroys Mechagodzilla's controls herself.
It Only Works Once: Godzilla takes Mechagodzilla's head off like he did before, but this time Mechagodzilla has a backup head that can't be removed so easily. It can also shoot a laser.
Large Ham: Doubles as Say My Name when Dr. Mafune shouts Katsura's name before he dies. The dub was hammier though.
Macross Missile Massacre: Mechagodzilla unleashes a torrent of lasers, rockets, and missiles at Tokyo and later Godzilla.
Market-Based Title: Hoo-boy, we have a lot to cover. Was theatrically released in the U.S. under the puzzling name of The Terror of Godzilla, in the UK as Monsters From an Unknown Planet, in Germany as Konga - Godzilla - King Kong: The Brood of Devils, and in France as Monsters From the Lost Continent. There are four different versions of the English title card alone (the original international version, the UPA TV version, the "new" UPA title card, and another variation of the new" UPA title card).
Mid-Season Upgrade: Mechagodzilla receives a backup head and... revolving hand missiles. Otherwise, he retains the same weapons and abilities he had in the previous film.
Naked on Revival: In the Japanese version at least. While reviving Katsura again, they show her breasts (unusual for a Godzilla film). Obviously, this is cut out in the English version so the film can obtain a G-rating. The scene in the Classic Media release.
They Called Me Mad!: Dr. Mafune was ridiculed for his staunch belief that there was a dinosaur living underwater near Japan. Apparently, no one ever sought him out and apologized to him after a certain event in 1954. Sure, he was referring to a completely different dinosaur, but still.
He also has apparently become mad as well, unfortunately.
Not only that, but according to the dialogue this happened in 1960 (not before Godzilla's first appearance), which means Japan had just recently dealt with two Godzillas and Angilas, but Rodan and Varan if those are to be considered canonical.
Title Drop: A subtle one of one listens carefully:
Commander Mugan: "That's when we will counterattack Tokyo with Mechagodzilla!"
If you listen carefully, he says "Mechagojira no gyakushu-da", which is the Japanese title of the film ''Mechagodzilla's Counterattack".
Tragic Monster: Titanosaurus. Constantly being used and forced to do things beyond his control, he is finally free at the end, only to face the wrath of a tired and bitter Godzilla, who didn't know about the mind control. Katsura can also count, to an extent.
Weaksauce Weakness: Averted. Titanosaurus is susceptible to sonic waves and they had to build a special weapon just to take him down. Without it the final battle may have gone very differently.
What Measure Is a Non-Human?: Katsura, being a cyborg, struggles with this throughout the film. It doesn't help that the Simians do their damnest to make her turn against humankind. Ichinose convinces her that she's still human because she can produce tears, and he says that even if she's a cyborg, he still loves her.
Whatever Happened To The Mouse: In the theatrical US release (and the home video releases of it), Katsura's suicide was cut out, and she vanishes without a trace after the aliens are defeated.
Also Interpol agent Kusakari, who disappears in the US cut because the scene of him getting executed by the aliens was deleted.
And Mafune's creepy gardener, who, in either cut, disappears after accompanying Katsura to the city and running from Interpol.
At least one of these scenes (Katsura's Suicide) manages to make it into the Toho Master Collection rerelease of the English-language version.
