Simple question: what's the greatest film your country has produced? Yes, you must pick one and only one. Of course, many films these days are decidedly international efforts, with cast and crew and financing and productions assembled from around the world, and some movies may therefore be fairly said to come from more than one country, but... use your judgment, I guess, and err on the side of non-international productions. (LotR, for instance, I'd call as American a movie as a Kiwi one, being produced by an American studio with a thoroughly international cast, so I'd discourage that as a pick for either country.)
I'll go first.
