The third movie photographer David Hamilton made might have been his best one yet. It is livelier and more interesting than "Bilitis" and "Laura", and also has a more convincing sense of time and place. You can actually believe that the characters and locale in the movie are real, and that they go on existing in between shots, and outside of them.
However, probably nobody watched a David Hamilton movie for the mise-en-scene. His movies were like artful softcore pornography. "Tendres cousines" actually seems to have less nudity than the previous two flicks. "Bilitis" and "Laura" both had lengthy communal shower scenes with young women frolicking naked. I didn't see any of that here, though there is of course still nudity.
What always struck me about this flick - and the only thing I remembered about it from watching it years ago - is that the male lead, a fourteen year old boy, is more strikingly beautiful than any of the women in the movie. At first, he detracts from the beauty of the female lead, because she is nowhere near as striking as he is, and you wonder why he is interested in her. Then later, when you get a better look at her, you realise she is beautiful too.
The plot features the same theme Hamilton used in his previous two movies: that of unrequited love. Poune (what a name) is in love with her cousin Julien, who is in love with his cousin Julia. His sister Claire is engaged to Charles, but he's got his eye on Julia. A maid at the house tries to seduce Julien and take his virginity, but is caught and fired after she strips naked and lies with him and gets his shirt off. He makes up for it later, though, bagging himself a couple of other girls. He doesn't even look like he's in puberty yet.
I enjoyed this flick more than the others. I just felt like it was more professionally done.
