Renoir changed the ending of René Fauchois's play. The play ends with the marriage of Boudu and Anne-Marie, whereas in Renoir's film, Boudu escapes 'from holy padlock' and heads for ' a future of independent, vagrant liberty.' Initially angry, according to Renoir, Fauchois threatened to have his name removed from the credits, but later changed his mind, and (in Cinéma 56, no.7, November 1955) said: "I have just seen the film again and I admired it and am happy to say so. As a very free adaptation of my work, Boudu belongs to Renoir." (Fauchois's career started as an actor with the Sarah-Bernhardt company, and in 1925 when Michel Simon played Boudu on the stage Fauchois was Lestingois.) In narrative terms, another major change by Renoir from the play, consists in shifting the centre of attention from the character of Lestingois to that of Boudu.[3]
Michel Simon was at various times, a boxer, a boxing instructor, a right-wing anarchist, a frequenter of prostitutes, pimps and petty crooks. He was extremely well read, a talented photographer, a hypochondriac, a misanthrope, owner of a vast collection of pornography and with a reputation for unorthodox sexual behaviour which he did not bother to deny. The writer Richard Boston has stated that, "Whether or not he was a pleasant man, he was certainly a complex one, with a good deal of Boudu in him," and Renoir called Simon "a genius of an actor...Boudu was conceived primarily to make use of the genius of Michel Simon."[4]
Michel Simon called Boudu a pique-assiette, a sponger, while the writer Richard Boston rejected the idea that Boudu had much in common with the hippies of the late 1960s, as Pauline Kael had suggested. "The Oxford English Dictionary says that hippie is a hipster; a person usually exotically dressed; a beatnik. None of this sounds remotely like Boudu. Boudu doesn't reject conventional values: he never had them in the first place: you wouldn't catch him doing anything as pussy-footing as 'rejecting conventional values.' " Rather, Boston argues, Boudu is what the French call a marginal. Boudu is anarchic, chaotic, and finally, a fool. An archetype, "these agents of chaos act out our secret desires. If we see a big bum we might want to kick it: Chaplin does kick it...Laurel and Hardy, the Marx Brothers, Boudu, and Hulot are the enemies of conformity, of what can be regulated. They are the awkward squad."[5]
