Since Anne Bogart began to develop the Viewpoints in the Experimental Theatre Wing of New York University (ETW) twenty years ago, her approach has become a training tool, a staging tool, an "everything" tool, adopted and adjusted by theatre artists around the world. The Viewpoints, a technique used to focus actors' awareness on different elements of performance (tempo, duration, gesture, spatial relationship), no longer remain exclusively among the avant-garde; rather, in the last decade, a generation of mainstream directors has begun to incorporate Viewpoints training and practice into the rehearsal process. Some have studied with Bogart; some have studied with her students; some have studied with Viewpoints creator Mary Overlie; and some have only attended a workshop.
