* WeCouldHaveAvoidedAllThis: Walter's reaction to the sheriff ''finally'' telling them about Leopold's experiments much later than he could have.

* AluminumChristmasTrees: Sargassum is a real plant, and it really is sometimes called the "weed of deceit", as ludicrously melodramatic as such a title sounds.

* DiesWideOpen: The girl that Dr. Leopold, er, "punches" to death. The problems with using a live actor for this trope rather than a dummy corpse are evident when she looks less like a dead body and more like [[{{Corpsing}} an actor trying very hard to act dead.]]

* DiesWideOpen: The girl that Zaat, er, "punches" to death. The problems with using a live actor for this trope rather than a dummy corpse are evident when she looks less like a dead body and more like [[{{Corpsing}} an actor trying very hard to act dead.]]

* HeroicBSOD: Martha gets kidnapped by the mad doctor, gets injected by the formula, narrowly avoids getting transformed into a fish-woman, and then afterwards she's not quite the same--zombielike, she follows the doctor into the ocean at the end.

* NobleBigotWithABadge: The Sheriff can be viewed this way, as he calls his assistant Ben "boy." However, [[RaceLift Ben was originally written for a white actor]], and the sheriff takes a fatherly attitude (addressing white characters as "boy" too). It's evident that "boy" was written with the characters' relationship in mind, regardless of skin color, but YMMV on how uncomfortable the end result is.

It's about Dr. Kurt Leopold, a {{mad scientist}} who wants to get revenge on all those who thought he was silly for wanting to make a half-man, half fish. Using a chemical of his creation (the titular "[=ZaAt=]"), he makes himself into his first test subject, and turns the local catfish huge and man-eating. Next steps: kill those who wronged him, and find a mate to breed the new race, and then [[TakeOverTheWorld conquer the universe]].

* LargeHam: Dr. Leopold, at least before he becomes Zaat. Unfortunately, everyone else in the movie is the [[DullSurprise exact opposite.]]

* PanAndScan: The film was never intended to be viewed in 4:3, so television prints show the walking catfish Leopold ''is wearing sneakers''.

WebVideo/RedLetterMedia [[http://redlettermedia.com/half-in-the-bag-zaat/ reviewed]] it as well, as did New York Daily News' Phantom of the Movies, a decade later in 1984. (It took that long for the film to reach the Times Square grindhouse theaters.)
