This week's Hidden Gem (#56 as we count down to #1) is an abstract but nevertheless, hypnotically engaging 1964 film from Czechoslovakia. Interestingly enough, this has been announced for release on Blu-ray by the Criterion label (April 16, 2019). If you've seen this one, please share your thoughts. If not, please let us know if it sounds like a film you'd like to see:
