"Actions" is the perfect size to carry around, and I've found it invaluable in preparing for auditions as well as fleshing out a role. The juice in this book is in the concept of characterizing a theatrical beat in one action word. Since theater is visual, it is critical for an actor to physically demonstrate the inner workings of the character, and this book is a great jumping off point. I did purchase a pocket size thesaurus to use with it, since on several occasions this book did not contain the exact word I was looking for. I've played four widely different roles since acquiring this book, and consider the hours I've spent looking for that perfect "aha!" word well worthwhile. I'm making much more confident acting choices, and I think my characters are more assured, clearly defined and authentic. Highly recommended!
