One film that may be less well known than others is TUNNELKIND (TUNNEL CHILD)
--Austria, 1990, directed by Erhard Reidlsperger.
 
(Sorry, that should be Riedlsperger)
 
It's about an Austrian girl who finds a tunnel under the Czech border just
as it's being enclosed following the quashing of the Prague Spring.  She
strikes up a friendship with a surveyor for the new fence.  An interesting
and not well-known film.
