Les Demoiselles de Rochefort is the follow up to Les Parapluies de Cherbourg but no sequel. From a musical viewpoint, one of the principal differences is that it is not through-sung; there is spoken dialogue. What it does retain is character, that sense of parochial lightness - and the sharpness of the drama when that goes awry.
Principally though Les Demoiselles is a fantasy ballet. From the first improbably shot taking from various perspectives on the Rochefort-Martrou suspension bridge to any number of ensemble set pieces on the streets of the town itself, co-ordinated costuming and choreography are the beating heart of the film. It's no surprise then - though a stunning coup - when the godfather of the Golden Age Hollywood musical Gene Kelly turns up (as a composer, i.e. as Legrand. Told you it's about him).
Gentlemen Prefer Blondes, it looks studied. Indeed Remy might even have filmed it as such to better realise the breeziness of the rest of his conception.
The essence of the film is distilled in a set piece, known as the concerto ballet, when Kelly and Françoise Dorléac finally come together to acknowledge the love that all but exploded into flower near the film's start. The sequence forgoes the natural causality of the story, making the same assumptions as the audience, and gets right down to the dancing in a gleaming, Elysian temple that is the music shop to the proto-Rachmaninov gushing of Legrand's ersatz piano concerto.
The bittersweet character - the poignancy of love - that the sequence carries became all too real immediately after the film was completed, as Dorléac was killed in a car accident.
