Cœur bleu (1980)

"In this journey, Courant's heroine wanders through the clouds and Pyrenees mountains way after the world's destruction [...] Songs by Brigitte Bardot, Marilyn Monroe and Leonard Cohen, scores by Vivaldi, Kraftwerk and Johan Strauss, they all form this eclectic and defying musical atmosphere from which Courant dreams about a point of view that would allow him to find a rhythm in a constantly changing abysmal paradise" -Diego Trerotola

Unfortunately the movie Cœur bleu is not yet available on HBO Max.
