The Swissmaker. A 1979 film about people who want to become Swiss citizens. Two Kantonal Police investigate the character and intentions of people who have applied for Swiss citizenship. Thanks to my friend, whose copy we borrowed, we enjoyed this satirical movie, filmed in Zürich and had some laughs about the stereotypes of Swiss expectations.
If you want a teaser and know some German, here is link to a trailer (without subtitles, but in High German, not Swiss German).

I have been corrected. This is not in High German! But maybe you can get the gist of it if you know German….
