This is a film from the transitional period between silents and sound. The film was shot without sound, then later dubbed. The result is a movie that is predominantly visual and this assists greatly if you have bought the V.H.S. version, because the subtitles are all over the place. Some dialogue has no subtitles whatsoever, some has titles for part of a conversation, and (maddeningly!) other parts have a subtitle half or even a quarter visible at the bottom of the screen. This is not the fault of Rene Clair however, who presents us with some great images of the streets of Paris, its low-life, and a peek inside the rented rooms of the poor people. The sound too is pretty good when you consider its original format, and the pretty but simple music conveys Clair's own enthusiasm to the listener.
The plot is somewhat incidental, but difficult to follow since it seems two near-identical men dressed in almost the same clothes are rolling dice to see who gets a girl. They are thwarted by a tough Parisian thief who looks uncannily like Basil Fawlty! But this does not really matter, just look at the sights and sounds of 1920s Paris, lovingly recreated in the film studio and see why Clair went on to become such a successful Hollywood director.
