John Abbott, author of The Improvisation Book, explains how theatre directors at every level can use improvisation in the rehearsal room. Foreword by Mark Rylance.'Improvisation can be used as part of the creative process of rehearsing a play. It can be a fabulous tool for exploration and discovery. It can strengthen the actor's commitment to their character. And it can create an environment of confidence and spontaneity.'Packed with useful exercises and improvisation scenarios, and examples from a wide variety of plays, Improvisation in Rehearsal reveals how improvisation enriches and enlivens the creation of characters, back-stories, relationships, shared histories and emotional lives. The book also demonstrates how improvisation can be used as a powerful tool in the foundation of a strong company, and when searching for the hidden depths and dynamics in a scene.Building on his own experience as an actor, director and teacher, Abbott writes with clarity and an infectious enthusiasm which will motivate directors to try the techniques for themselves. As Mark Rylance says in his Foreword, this book 'will inspire and delight its readers'.
