There is hardly anything I can add to the already effusive comments by others at this site. This film is a painting in motion. Theodorakis' music beats in one's heart and the Dali-like dream sequence is unforgettable.
I first saw this film in Chicago in 1962 and again in New York the following year. A whole group of us sat through the film twice, and became obsessed with it.
For forty years, I have tried in vain to find the music, and later the tape of this film, but to no avail. It is never shown on TV and I have not been able to find it even in a New York art house for many years.
What a pity that a gem such as this should be unavailable. All I have of it is a 45-rpm recording of two of the films songs, but not the ballet.
There was another movie made, "Honeymoon," or "Luna de miel" in 1959 starring Ludmilla Tcherina and Anthony Steel which featured the ballet in a different setting, but, alas, that is also unavailable on tape or DVD.
I would be happy to spearhead any attempts to make the original film available on DVD if I knew who to contact. I once wrote to the French Film Office, but they never answered me.
