This work has inspired the work of countless actors, directors, and writers in theatre, television and film. Spolin's improvisational techniques have changed the very nature and practice of modern theatre. This third edition updates the more than 200 now-classic exercises and adds 30 new ones. It adds 30 traditional theatre games that are frequently used as warm-ups. It includes Spolin's explanations of key concepts crucial to her programme, and collects "The Sayings of Viola Spolin" and adds a glossary of phrases for teachers and directors, with Spolin's definitions of their meaning and value. Most significantly, though, this edition makes available "The Lone Actor". In this section, Spolin offers games for individuals to play when they are alone. It is an important piece that should expand Spolin's teachings and influence to an entirely new audience.

Viola Spolin's Theater Games for the Lone Actor offers theater games and side coaching for the solo player. Available for the first time, this handbook presents more than forty exercises that allow actors to side coach themselves at home, in rehearsal, or in performance. Building on her seminal Improvisation for the Theater, Spolin challenges the actor to develop an ability to enter present time, "a moment of full consciousness, awareness, continuous time, a timeless moment . . . with all of your responses awake and alert, ready to guide you . . . allowing you, the real you, your natural self, to emerge."
Spolin's improvisational techniques changed the nature and practice of modern theater. Her work has inspired actors, directors, teachers, and writers in theater, television, and film. Her techniques have also influenced the fields of education, mental health, social work, and psychology.
