The Sphere

From the author of Jurassic Park, Timeline, and Congo comes a psychological thriller about a group of scientists who investigate a spaceship discovered on the ocean floor. In the middle of the South Pacific, a thousand feet below the surface, a huge vessel is unearthed. Rushed to the scene is a team of American scientists who descend together into the depths to investigate the astonishing discovery. What they find defies their imaginations and mocks their attempts at logical explanation. It is a spaceship, but apparently it is undamaged by its fall from the sky. And, most startling, it appears to be at least three hundred years old, containing a terrifying and destructive force that must be controlled at all costs.

Theatre of the Sphere is Luis Valdez’s exploration of the principles that underlie his innovations as a playwright, teacher, and theatrical innovator. He discusses the unique aesthetic, more than five decades in the making, that defines the work of his group El Teatro Campesino—from shows staged on the backs of flatbed trucks by the participants in the Delano Grape Strike of the 1960s to international megahits like Zoot Suit. Opening with a history of El Teatro Campesino, rich with Valdez’s insights and remembrances, the book’s first part provides context for the development of the Theatre of the Sphere acting method. The second part delivers the conceptual framework for Valdez’s acting theory and practice, situating it in Mayan mathematics and metaphysics. The third part of the book applies this methodology to describe the "viente pasos," the 20-element exercise sequence that comprises the core practice of El Teatro Campesino—strengthening the body, balance, precision, and flexibility but also leadership, collaboration, observation, vulnerability, trust, and expression of passion; of consciousness of time, place, self, community, language, and belief; of honour, faith, morality, and commitment. The book concludes with the full text of Valdez’s poem, "El Buen Actor/El Mal Actor," and a comprehensive bibliography for further study. This is a vital and indispensable text for today’s actor, as well as scholars and students of contemporary theatre, American and Chicano performance, and the process of theatre-making, actor training, and community performance.
