Theatrical improvisation festival in Massy, shows and improv matches in Essonne
The M'Improvise Festival is the annual meeting point for theatrical improvisation in Massy (91300). Organized by local improvisation associations including Les Tréteaux Amateurs de Massy and Les Impropotams, it brings together local and guest teams each year for improv matches and shows open to all. A festive and participatory event at the Petit Théâtre de Massy or Espace Lino Ventura.
The M'Improvise Festival is the flagship event for theatrical improvisation in Massy. Driven by the territory's improvisation associations — primarily the Tréteaux Amateurs de Massy (TAM) and Les Impropotams — this annual festival brings together amateur and semi-professional actors and guest teams in improvised jousts that blend humor, creativity, and camaraderie.
Theatrical improvisation is a living art form in which actors construct scenes in real-time, without prepared text, which can take comic, dramatic, poetic, or absurd directions. Born in the 1970s in Canada and popularized by Robert Lepage, the "improv league" has spread worldwide and given rise to a community of passionate practitioners. In Massy, this practice is very much alive thanks to the commitment of local associations.
The Tréteaux Amateurs de Massy are at the origin of the festival, with their historic event TinTAMart, an amateur theater festival that integrated improvisation into its programming. Les Impropotams, an improvisation theater troupe founded in Massy, have strengthened this dynamic with their regular shows at the Espace Lino Ventura (Place Saint-Fiacre, 91300 Massy) and their participation in regional and national improvisation championships.
The festival's flagship format is the improv match, pitting two teams of actors against each other in categories set by a referee in front of an audience that also acts as referee and participant. Spectators can influence the course of the match through their reactions, votes, and sometimes suggestions. This interactive format creates a unique bond between stage and audience, making each evening a unique and unrepeatable moment.
The 2025 edition of the M'Improvise Festival brought together several improvisation teams from Essonne and neighboring regions in matches and shows held at the Petit Théâtre de Massy (18 rue Gabriel Péri) and the Espace Lino Ventura. The program alternated competitive matches, themed evenings, and long-form shows, offering a complete spectrum of contemporary improvisation.
The 2026 edition of the M'Improvise Festival is planned for Massy and will once again bring together local and guest teams in improvised jousts. Program and dates to be confirmed with the organizing associations TAM (tam.asso.fr) and Impropotams (impropotams.com).
Massy is one of the nerve centers of theatrical improvisation in the Île-de-France region. Beyond the festival's producing associations, Impro Essonne (founded by Robin Gueguen) offers professional training and regular workshops, nurturing a pool of local talent. The diversity of associations and practices makes Massy a particularly active territory for the Parisian improv scene.
