tbf, they couldn't really film Apocalypse Now in any Vietnamese like jungles in the US and have it look legit and have the extras that they needed...Yeah, it's always weird. I think often it's matter of financing, which means little in terms of the country of origin of a film. Also, in that list, The Prestige feels quite British in various ways, but I don't know if there is anything British about it except for some of the setting and actors; and while Apocalypse Now counts as coming from the US, I think filming happened pretty much exclusive in the Philippines - which nonetheless would never be considered as its country of origin.
Which reminds me; it is funny to see certain movies that are set elsewhere but clearly are filmed in California. The topography and look of southern california is quite distinct.
