Has anyone seen the Bulgarian film The Attached Balloon? In my imagination it's already among the handful of most wonderful films. So perhaps a film to stay unseen to avoid possible disappointment! I'm delighted to find it gets great ratings at imdb, confirming my belief. 

And the American Quay twins' British animated short Street of Crocodiles should really be classed as a Czech film, not only for its quirky macabre surreal character, influenced by Svankmajer + Kafka- it obviously sees itself as Czech. I love it.
