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.
