The short film depicts the French artist Jean-Charles de Quillacq performing his own alter-ego as he seeks for inspiration in his atelier, where his behaviour evokes excitement, effort and sex. Most of the time naked, Quillacq wears masks that strongly resemble the artist. The masks are alterations of his own face and those of his siblings. Over the course of the short film, the artist's alter-ego engages in domestic chores and repeats mechanical gestures that are difficult to classify. Masturbatory, almost autistic gestures that might trouble the spectators mind. The camera follows his body, under the inexpressive silicone masks, drawn into sexual and sometimes obscene actions, where the figure of the artist is cut up in a stream of piss and sweat. Quillacq's work explores questions of repetition, body functions, comedy and satirizes our relationship to the economic world and its capitalist logic. «Getting a younger sister thinking to myself» has been produced for an exhibition at the Museum of Modern Art in Paris. It is either shown in a black cube or screened on a monitor.
