Got to be Obecna Skola (sorry, no accents on my keyboard :? ) aka The Elementary School. It is SO nostalgic for an era I didn't know but wish I did! It is a great movie, up there with Cinema Paradiso, I really think that the European film industry is consistently turning out far better material than America, and has been for many years now. It is sadly blighted by the problem of language, and as such fails to hit large audiences. At least with the growth of the internet many of these films are now becoming available to their fans.
