The tiny Principality of Liechtenstein is, on a per capita basis, a very wealthy nation. But with a population of only 39,000 people, there are certain features common among larger nations that it lacks, such as airports, an army, a currency, and even embassies in foreign lands. It also lacks a film industry centered within the nation, producing movies by and for Liechtenstein and employing primarily its own citizens.
Nonetheless, there is one feature-length film that can be considered a truly Liechtensteiner film in that it was shot within that nation and tells a story that takes place there. The 1958 film Kinder der Berge tells the story of a Liechtensteiner woodcarver who experiences a miracle attributed to a statue of the Virgin Mary that he carves.
The actors were primarily German and Swiss, with the main character portrayed by the acclaimed Swiss actor Maximilian Schell. But a prince and princess of this alpine monarchy also make appearances to give this film a definite Liechtensteiner flavor.
I've embedded a clip from the film.
