Book excerpt: Stanislavsky’s system of actor-training has revolutionised modern theatre practice, and he is widely recognised to be one of the great cultural innovators of the twentieth century. The Routledge Companion to Stanislavsky is an essential book for students and scholars alike, providing the first overview of the field for the 21st century. An important feature of this book is the balance between Stanislavsky’s theory and practice, as international contributors present scholarly and artistic interpretations of his work. With chapters including academic essays and personal narratives, the Companion is divided into four clear parts, exploring Stanislavsky on stage, as an acting teacher, as a theorist and finally as a theatre practitioner. Bringing together a dazzling selection of original scholarship, notable contributions include Anatoly Smeliansky on Stanislavsky’s letters; William D. Gunn on staging ideology at the Moscow Art Theatre; Sharon Marie Carnicke and David Rosen on opera; Rosemary Malague on the feminist perspective of new translations; W.B. Worthen on cognitive science; Julia Listengarten on the avant-garde; David Krasner on the System in America; and Dennis Beck on Stanislavsky’s legacy in non-realistic theatre.
