Wikidata records no filming location for Passion Fish (1992) at all, not a place, not even a country. There is nothing to pin, and this page says so rather than guessing.
Why there is no pin
Its Wikipedia article also says it was filmed in Louisiana, without naming a place, so it is not on the map.
