Based on a play by Georges Neveux and raised in a tone between dreamlike and eerie, the film develops a fantasy filled with allegorical resonances. Marcel Carnรฉ achieved with "Juliette ou La clef des songes" which I think deserves to be considered his best film "installed" in the poetic realism of which he is their peak rating. Special mention deserves the splendid work of interpretation of its main actors.
