Where was This Happy Breed filmed?
1944 film by David Lean
Wikidata records no filming location for This Happy Breed (1944) 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 United Kingdom, without naming a place, so it is not on the map.
Filming locations that are mapped there: United Kingdom
