I saw this back when I was the same age as our protagonist here, 15 year old Peter.
Den sommeren jeg fylte 15 (The summer I turned 15) is the story Peter is telling the about a special summer, when he is invited over to summer holiday from bickering parents, to his aunt and uncle in th country. He's been there before, but this summer was quite one to remember.
The film is based upon the Youth novel by Knut Faldbakken, and is about a boy sensing his first real sexual feelings. Directed by Knut Andersen, the man behind some of Norwegian film's most popular classics, this is a well-told coming-of-age story.
Peter has entered an age where he starts noticing sexual tension and what's going on around. That is like noticing that his aunt and uncle also quarrels, when they think he is not aware. He also discovers that his uncle is having an affair.
Together with a comrade the same age, he uses his time looking at old erotic magazines. But the really important thing is when he meets up with a girl his same age and a 6-7 year older single mother who is not afraid to bathe naked, both giving him his first real sexual feelings and sexual experiences. His first real kiss before I go on...
It's a great teen-summer feel from the seventies here, which adds to this as a melancholic movie.
There are also some subtle dramatic sequences here, but the film can be viewed by anyone grown enough to understand the sexual tension, but I think teenagers will appreciate it most. Well played by all actors, and a charming story, but still, I must say it feels quite dated today.
