I've just seen this film for the first time over the Xmas period on a Chinese cable television. It's a classic. Marceau is just the epitome of beauty itself and charming throughout the film. Perez, too, is very watchable.
Unlike many love stories on film this has none of that awful sentimentality, but is strewn with many comical moments. The plot centres around Perez falling in love with Marceau but desiring to keep the relationship fresh by keeping her at at distance. At the same time Perez is planning to marry his girlfriend, played by the equally beautiful Marine Delterme.
Forget tired old classics like "Brief Encounter" and "The Seven Year Itch" and watch this instead. The only thing that stops me giving it more out of ten is that I would have liked to have seen much more of both the beautiful Miss Marceau and also Miss Delterme. Then it would have been a classic among classics!
