I See Sea People
What was thought to be a flick about mermaids who lure stinky fishermen to their watery graves, then crack their skulls open like clam shells and feast on their gooey duck brains, turned out to be a fantasy Disney-esque tear-jerker. Dammit.
Hume Cronin, all but reprising his role in Cocoon (1985, another breast-less feature), is an actual mermaid (but he prefers to be called “Sea People”). He and his mermaid wife eat seaweed and pump seawater into their sleeping tanks, which are industrial strength aquariums.
Hume (that name sounds SO made up) looks as old as the barnacles growing on the bottom of the boats that sail in and out of the unsuspecting harbor. He has no fins, visible gills, or creature-like attributes, but does manage a decent dog paddle. In short, Sea People (1999) is out to sea.
