Big drink of water Wade Popwell is a furry, portrait-sketching fish monster in Don Barton and Arnold Stevens' incoherent 1971 sci-fi feature inspired by news articles about walking catfish. The fishy fiend is murderous mutated scientist Dr. Kurt Leopold (Marshall Grauer), a sourpuss intent on wiping out humanity once he's created a fish-woman mate out of one unlucky federal agent (Sanna Ringhaver). Can her agency partner Walker (Dave Dickerson), the town's redneck sheriff (Paul Galloway from J.D.'s Revenge), or his dumbass deputy (Jaws 3D's Rich Valliere) save the planet from a catfish takeover? Filmed around Jacksonville, Florida and originally screened exclusively for the pissed-off patrons of southern drive-ins, Barton's bottom feeder suffered an abortive Times Square run when reissued by the late Terry Levene's Aquarius Releasing as Blood Waters of Dr. Z.
