The famed "object exercises" of Hagen are described here for the first and possibly only time. In fact, there are three divisions of the text: part one is The Actor, part two is The Object Exercises and part three is The Play And The Role. Hagen and Herbert Berghof practiced and taught these lessons at the Berghof school in New York (which produced at least a hundred Broadway and Hollywood household names) and Hagen pursued her own simultaneous acting career according to them. Sense memory, identity, substitution and many other topics are covered as they were in the classes from 1947 through the 1960's.
