American analog, you say?
I'm no cinephile, and
the moviegoers here can no doubt think of a whole bunch.

The only that comes to mind from the few movies I have seen,
is that
"Lake Placid" horror movie with Bridget Fonda,
about these ginormous crocodiles. In Lake Placid, obviously.

Betty White, that wholesome yet exuberant personality of an actress,
plays the old lady who feeds the ginormous crocodiles ...
on one occasion,
she fed her husband to them.
At the end of the film,
she is seen barefoot sitting at the edge of the dock,
feeding the tiny little baby crocs floating around.
