Boudu sauvé des eaux

Boudu (Michel Simon), a tramp, jumps into the Seine. He is rescued by Mr. Lestingois, a gentle and good bookseller, who gives shelter to him. Mrs. Lestingois and the maid Anne-Marie (Mr. Lestingois' mistress) are far from delighted, for Boudu is lazy, dirty and salacious...

Pauline Kael called it, "not only a lovely fable about a bourgeois attempt to reform an early hippy...but a photographic record of an earlier France." The film was remade in 1986 for an American audience as "Down and Out in Beverly Hills", directed by Paul Mazursky.

Now, I don't know that Boudu is a hippie. That might be an insult to him, and it is certainly an insult to hippies. But there's plenty of comic potential in wealthy people trying to reform the slobs of the world. This theme is addressed in other films, such as "Trading Places", and the comedy writes itself.
