I saw this film as a student at Cambridge nearly 50 years ago and it has haunted me ever since. I longed to find a showing, then a tape, then a DVD, then a blu ray and never have I ever been able to find it. It is the nearest thing I have ever felt to true hallucination. A beautiful, immersive unforgettable experience. Today I found it again for the first time in decades. I am so thrilled by this. it's a jewel, a strange but wonderful jewel and a reminder that Soviet art did, after all, have room for diversity and expressions of artistic sensibility. Watch and be amazed.
