Once, in Eric Morris' Acting class, I mistakenly referred to this book as Irrelevant Acting. Nothing could be farther from the truth. This is one of the best books on acting ever! The exercises and work in this book have enhanced my acting tremendously, given me a way of working that is unmatched by any other acting book I've ever come accross (and I've read a ton of em) and has made me a powerful teacher and director in my own right. It explains Eric's Technique of Freeing the Instrument (Explained in great detail in his No Acting Please which should be read prior to this book.) It explains a new way of looking at material and personally connecting it to the actor through choices and choice approaches. It truly helps make the actor an artist in that he creates and is truly using himself. If you utilize this work and combine it with some common sense of your own (if you don't combine it with some common sense--some of it can get you into trouble) your acting will take on a new dimension; you will be more open as an actor artist and human being.
