At the time of his death, Stanislavsky considered Nikolai Demidov to be 'his only student, who understands the System'. Demidov's incredibly forward-thinking processes not only continued his teacher's pioneering work, but also solved the problems of an actor's creativity that Stanislavsky never conquered. This book brings together Demidov's five volumes on actor training. Supplementary materials, including transcriptions of Demidov's classes, and notes and correspondence from the author make this the definitive collection on one of Russian theatre's most important figures.
