History Film / TheBloodWatersOfDrZ

* SoundtrackDissonance: ''World War II Boy'' sung over the beginning which is upbeat and catchy in contrast to the doughy, unimpressive evil scientist.

* NobleBigotWithABadge: The Sheriff. His assistant Ben sees him as a fatherly figure, so it could be an affectation rather than any real racism. He also calls a white photographer "boy", so he may just be an InnocentBigot.
** RaceLift: Ben was originally written for a white actor; it doesn't explain why the script wasn't adjusted to take that into account.

''The Blood Waters of Dr. Z'', also known as ''Zaat'', is a 1971 film about Dr. 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]].

* {{Fainting}}: Near the end, the female scientist faints when Dr. Leopold breaks into the cabin where they've set up shop. She then stays unconscious as he roughly carries her, over his shoulder through a humid, noisy, treacherous swamp, for ''several miles''.

* TheyCalledMeMad: "They think I'm insane... they're the ones who are insane!"

* NotableOriginalMusic: [[https://www.youtube.com/watch?v=-m859q53-iQ "World War II Boy]]" by Jamie [=DeFrates=]. If you interpret the mildly incoherent lyrics to the ''World War II Boy'' to being in reference to Dr. Leopold, then it counts as his VillainSong, but with a rather upbeat, catchy tune.
-->''Hey World War II boy
-->Foreboding battlewagon fodder
-->Forelock missing with your luck
-->Keeps you up at night
-->Mare's moon tangles both your feet
-->Drags you down helplessly step a fake
-->Tombstones piling up your last mistake
-->We all wait for you; give us a break, give us a break
-->Sashay, sashay through the sarcasm
-->Stalking, skulking through the sargassum
-->Planning revenge on your friends
-->Planning revenge on your friends
-->Planning revenge on your friends''

* PainfulRhyme: Sarcasm and sargassum do ''not'' rhyme.

-->Holding back a wagging fatter
-->Olaf messing with your luck

-->Mel Pool hang a cocoa bean
-->Drags you down helplessly step of fate
-->Tombstones are piling up your last mistake
-->We all wait for you to give us a break
-->Give us a break!
-->Sashay through the sarcasm [sic]

-->Sashay through the sargassum
-->Planning re-veenge on your friends!''

** If getting the canisters to the ocean will mutate all sea-life then he did indeed succeed. We don't know if the bullets killed him, and also he got the girl...kind of.

* 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.

* [[TodayXTomorrowTheWorld Today Florida, Tomorrow The World!]]: Emphasized when Catfish!Leopold emphatically marks Florida with an "X" after infecting the water.

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.)

* LeaveTheCameraRunning: MST3K fans were lucky in that the televised version used for the show cut the first 15-20 minutes, which was nothing but Dr. Leopold ''walking around'', ''checking equipment'', and ''reading notes'', and ''nothing else''.

* HeroicBSOD: Martha gets kidnapped by the mad doctor, gets injected by the forumula, 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.

* ScienceMarchesOn: Sargassum fish are no longer a danger to Floridian waters - in fact, they're endangered.
