Seen on Pittsburgh's Chiller Theater in 1974
1966's "Terror Beneath the Sea" is a forgotten sci-fi from Japan, less surprising once you learn it's from neither Godzilla's Toho, or Gamera's Daiei. It's actually a Toei production, one of three that made it to American shores, with "Magic Serpent" and "The Green Slime" better remembered. Apart from future martial arts star Sonny Chiba, we have teenage blonde Peggy Neal, who went on to star in Shochiku's "The X from Outer Space," who promptly disappeared from the scene. The Gill Man costumes are initially intriguing, but become obvious through repetition, though the prospect of human beings being transformed into amphibian cyborgs manages to produce some effective moments. Director Hajime Sato really struck paydirt with his final film, 1968's "Goke Body Snatcher from Hell" (also from Shochiku), as nightmarish a combination of horror and sci-fi as any made in Japan. "Terror Beneath the Sea" aka "Water Cyborgs" was frequently seen on television through the late 70s (not much since), airing three times on Pittsburgh's Chiller Theater from 1974 to 1978.
Never Trust A Fish-Man With A Loaded Gun...
In AGENT X-2: OPERATION UNDERWATER, a mad scientist is bent on world domination through his army of cyborg-mutant fish-men. Only Sonny Chiba and his scuba partner can save the Earth from hideous totalitarian control.
They'll have to stay strong as they encounter the scientist's terrible gun-toting sardines!
This movie is loaded with enough cheeeze to fill 10 nuclear submarines! Is it absurd? Of course, but it's also highly entertaining...

It's mysteriously soothing and entertaining.
I like the simplicity of it. You couldn't intentionally make a movie like this; it's just some kind of magic that falls into place, but the audience has to go along with this kind of accidental wackiness or it will fail to entertain.
It's a great comedy.
This is a fun adventure flick that conjures up feelings of nostalgic Japanese horror. It's not scary but will keep you in stitches during the viewing and long afterwards. This film would fit nicely into a "films so bad...they're good!" library. It's worth at least one viewing if only for the laughs and the special effects.......oh, they're great!
EERIE sensation sure to TERRIFY the nation!
YOU, thinking of Japanese monster horror, will likely picture either Godzilla or some kind of bodily mutilation, likely involving lots of tentacles (both fair).
YOU probably think you've seen it all.
But YOU have yet to experience the mid-point somewhere in between: a thrilling, chilling, underwater adventure so sixties it's hip! It's now! And how! Behold: the delightfully nostalgic, charming murk that is... TERROR BENEATH THE SEA!
(bum bum buuuuummm!!!)
SHRIEK in terror,as you attempt to uncover the (not so mystifying) mystery of the strange marine sightings interrupting underwater torpedo tests!
CRINGE at the gloriously wooden overacting, especially the nearly unbearably whiny Peggy Neal, and one navy sergeant bearing an uncanny resemblance to Bradley Cooper!
GROOVE to the funky James Bond vibe of the underwater base, matching uniformed minions, and cackling megalomaniac foe, all given a swingin' sizzle by the slam-banging jazzy adore!
GASP at the strange, eerie underwater creatures - like the Creature of the Black Lagoon with his face caught in a vice! Then HIDE YOUR EYES from the stop motion transformations creating the abominations (see? We promised bodily mutilation!)...which would likely be more memorably grotesque with a higher budget, so the actors weren't left looking like they have shredded condoms all over their faces.
PUZZLE at the fish-men being referred to as cyborgs, and how their actions are controlled by an outrageously 60s wall dial. But don't sweat the details - the film sure doesn't.
CHEER as dashing martial arts star Sonny Chiba finally (finally!) gets to unleash some whoop-ass in a fantastically campy explosive finale, after spending too much of the movie frowning and being imprisoned - even if he does more shooting than martial arts-ing (boo).
You ask yourself: are your nerves (or attention span) up for the spectacle, the pizazz, of this frightfully fun creature feature?? Well, there's only one way to find out. Take the plunge with Sonny and Peggy. Steel your nerves. And uncover the outrageous odyssey that is... TERROR BENEATH THE SEA!
-5/10
