Where was The Lost Battalion filmed?
2001 television film directed by Russell Mulcahy
Wikidata records no filming location for The Lost Battalion (2001) 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 Luxembourg, without naming a place, so it is not on the map.
