How can we talk artistically about the contamination of the world by chemicals? How can we bring to light the invisible damage that is causing subtle alterations both inside and outside us? Having attempted to describe in documentary form the bath of industrial chemistry in which we are all now swimming, documentary filmmaker and theatre-maker François de Saint Georges wants to invent a visual, video, sound and theatrical practice capable of responding through the imagination to this violence of the colonisation of the body by chemistry. How can we make the invisible visible? What is it about our bodies that we are not yet aware of, but which gradually emerges? This two-stage research project - putting together stories of chemical contamination; studying the theatrical physicality of contamination, in particular through the practice of butô - should enable us to lay the foundations of this new practice and develop a new formal language.
