ABSTRACT François Ozon’s Regarde la mer/See the Sea uses the generic codes of a psychological thriller in order to portray femininity in a state of flux. Although Ozon is one of the most established contemporary French auteurs, this film is often overlooked in studies of his work. This article explores Regarde la mer as one of Ozon’s many contributions to a specific genre. The ‘psychological thriller’ relies heavily on suspense and ambiguity in order to function, and much of the film’s ambiguities are built around a sense of ambivalent sexual tension. In addition to the analysis of genre, this article approaches this ambivalent sexual tension from a queer perspective. Many normative configurations of gender are transgressed in the film, and the article identifies how this is conveyed in its expressive visual style. Furthermore, the film interrogates traditional female roles, such as ‘wife’ or ‘mother’. As a result, Regarde la mer draws on the aforementioned generic codes in order to subvert normative discourses of femininity.
