W is a research collective that studies action in a performance setting. What does it mean to act as others watch? What characterizes the relation we call theater?

To answer these questions, W simultaneously develops three complementary approaches: a practice, which builds tools and techniques for the actor; a critical method, which suggests reception guidelines for the spectator; and a theory, which works to define notions useful to the first two approaches.

In particular, W produces games, a lexicon of operational notions, a critical seminar, a theoretical apparatus, articles, conferences, research sessions, as well as school visits.

W was born in 2003 out of a project on the conditions of collective verbalization in an improvisational setting (Bloc, Centre Choréographique, Tours). That work was followed by another project, in which Joris Lacoste and Jeanne Revel collaborated with Joao Fiadeiro on his method of Composition in Real Time (CND, 2004). It has since evolved on its own.
In practical terms, W has run various hands-on sessions with actors: in 2006, at the Théâtre National de la Colline and at Cip-Idf, and in 2008-9, at Les Laboratoires d'Aubervilliers.

W helped develop Joris Lacoste's performance, Purgatory, at the Théâtre National de la Colline in 2007.

In addition, W has organized several research seminars: in 2005-2006, at the University of Paris III in collaboration with the Théâtre de la Colline; in 2007-2008, at the Laboratoires d'Aubervilliers, in partnership with the University of Paris 8's Department of Dance and the Masters Stage Directing Program at Paris 10; and, in 2008-2009, in partnership with the review Art21.

From 2007 to 2009, W was in residency at the Laboratoires d'Aubervilliers.

From 2008 on, W held W-Games at various festivals and art centers (Printemps de Septembre à Toulouse, Bétonsalon à Paris, and 3bisf à Aix-en-Provence).
