It's funny and a bit unusual but three of the stars of this movie have already worked together in the movie named in my title.Regarding this one, it could be a biopic about my parents and the time they conceived me, because it happens in France in the 70's. From my point of view, it was a great time then: the clothes were full of colors and society was boiling with talks about freedom and revolution. The other trend of this time is the so-called sexual liberty that gives the title to the movie: it was a time when old locks on sex were broken and it was before AIDS. Compared to another french movie also with Geraldine where protagonists are also swingers ("Je pense à vous" ),I think this one is much better because the couples are naive, idealist and lost. Finally, with their experiences bad or good, they gain maturity.As always, Geraldine is the delicate rose but the movie is also an opportunity to see a good Roschdy Zem and our a clone of Penelope, Marie Vialle as Juliette.
