This chapter begins with the idea of utopia which was the original theme of Coline Serreau's first documentary and which is central to her first fiction film, Pourquoi pas!. The 'community' created by the three bachelors could be seen as another alternative to accepted gender roles, and a variation of the ideal society created by the trio of Pourquoi pas!. The chapter examines the ways Serreau endlessly rewrote and re-created her ideal communities from one film and one play to the next. Taking intertextuality in its wider sense, the chapter analyses the direct and indirect influences and quotations from the 'philosophical century' and to a lesser extent from the seventeenth century. It demonstrates Serreau's originality and skilful synthesising of a number of inherited genres, from the conte philosophique to the fairy-tale.
