This 35mm screening is part of the season (details here) celebrating the 60th anniversary of the Curzon Soho and was the film which premiered in the UK at the cinema, then known as the Columbia. Gigi star Leslie Caron will be on hand to introduce the film.
Chicago Reader review:
Lerner and Loewe turned Colette's novel into the archetypal "Gallic romp," but while their score often falters, Vincente Minnelli's mise-en-scene does not (1958). It's easy to drift away from the story and become absorbed in Minnelli's impossibly delicate textures, but there is a little something here for everybody. Maurice Chevalier sings the Humbertian anthem "Thank Heaven for Little Girls," Louis Jourdan and Leslie Caron make competent lovers, and it's Academy Awards (nine to be exact) all around. With Hermione Gingold, Jacques Bergerac, and Eva Gabor.
Here (and above) is the trailer.
