Just as the First Studio, led by his assistant and close friend Leopold Sulerzhitsky, had provided the forum in which he developed his initial ideas for the 'system' during the 1910s, he hoped to secure his final legacy by opening another studio in 1935, in which the Method of Physical Action would be taught. The Opera-Dramatic Studio embodied the most complete implementation of the training exercises described in his manuals. Meanwhile, the transmission of his earlier work via the students of the First Studio was revolutionising acting in the West. With the arrival of Socialist realism in the USSR, the MAT and Stanislavski's 'system' were enthroned as exemplary models.
