Under the Roofs of Paris

Under the Roofs of Paris is a 1930 French film directed by René Clair. The film was probably the earliest French example of a filmed musical-comedy, although its often dark tone differentiates it from other instances of the genre. It was the first French production of the sound film era to achieve great international success.
