This book is a distillation of a lifetime in film that discusses the theory, practice, aesthetics, history and personal experiences of the author in the world of animated film. From advice to the most mundane, such as using 3X5 cards for storyboards vs. using store-bought panels, to the most practical, like what to do when a producer proposes not paying one for the "experience" of a professional job, the book is a wide raging look at the animation industry. An innovative teacher as well as animator, the book extensively covers teaching strategies, syllabuses and exercises to assist teachers in their own teaching environment. The over 1000 illustrations which accompany this text are included in Animation Rules! Book Two Art. If the philosophy of the UCLA Animation Workshop is One Film, One Filmmaker the philosophy of this book is Two Books, One Field.
