Action Theatre is an improvisational performance technique developed by the American performance artist, Ruth Zaporah. Action Theatre is defined by its focus on embodied awareness, the tracking of the present moment through sensory experience, and by a structured training that uses exploration to build the performer's 'formal dexterity and the ability to “listen” to oneself and one’s acting partners'. This physical theatre technique is documented in Zaporah's 1995 book, Action Theatre: The Improvisation of Presence.
