David Hamilton was a 70s photographer, much admired and copied in his time, who ventured into movies. His work in that medium repeats many of his photographic preferences and styles, with soft lighting and colours, slightly off-focus images, pretty young girls and by no means least, a degree of nudity.
Hamilton's movies are far less known than are his still images and the books within which most were published. It may be that four of the five were made primarily for the French Art Cinema movement in French. I know that his first such effort, Bilitis, did receive a limited UK distribution but possibly not any other. Most of his preferred models and actors were unknowns and many were students of ballet or dance who were used for their litheness, ability to create and hold a pose, and also for their beauty. No less so here.
Primarily a coming-of-age story told in relatively few words, the movie relies mostly on its imagery, concentrating on the perceived youth and innocence of its cast. Hamilton typically would use as models those who looked much younger than their true age in order to portray pubescence without any risk of legal intervention. UK law, and I believe French law, permitted persons 16-18 to pose nude if parental permission was given. US law prohibits such activity if under 18 so that Hamilton's films may well have been in breach of their standards. That alone may explain the limited distribution of his movies.
Hamilton was neither a trained or experienced scriptwriter or director, and it shows! Consequently, the movie can best be described as satisfactory but not good and would not be a candidate for any major award.
Enjoy it for its imagery, lighting and techniques and for Hamilton's easy ability to extract the last ounce of beauty from his cast, if nothing more.
