Every dot is a place where a film or a series was really shot, taken from the filming location statements on Wikidata and from the filming sections of Wikipedia articles. 14,611 locations from 9,201 films and series, across 156 countries.
It is not complete and it is not meant to look complete. It holds what Wikidata and Wikipedia actually record, so India has 406 locations against an industry that makes more films than Hollywood, and about half the dots resolve to a town rather than to the exact spot.
I hope to add more points and items on the map. Free, no ads, no signup: https://thefilmmap.com/
You're doing good work and I wish you the very best. We can bounce ideas if you want. I'm not in a position to undertake this development with my present responsibilities but if implemented, i would love to contribute the few locations I'm aware of.
