Second feature movie from Klapisch, and first of many with Romain Duris, one of his favourite actors, "Le péril jeune" is a masterwork, and a cult movie.
It manages to capture the spirit of a time (mid 70s) and of a generation and relies to do so on a group of talented actors.
I can only strongly recommend you this movie and hope you'll feel its magic!
Compared to others movies around that main story - a group of youth, having fun, going to school, growing into themselves, living - it does so with such freshness, you'll want too, to be part of that group
It will make you come back to your school time - even if you're not part of that generation, like me!
On top of that, we can feel that despite telling a story incorporating personal memories, he does so while laughing at that memory and the movie is infused with that fact. It will then be honed and used very efficiently in its most known work "L'auberge espagnole'.
