This book examines the phenomenon of adapting musicals originally written for the Broadway or West End (London) stage into Hollywood movies. It highlights tensions between live and recorded media, between the culture of the East and West Coasts of America, and between producers on Hollywood and Broadway. The book is divided into sections dealing with identity, technology, audiences, music, stars and multiple adaptations of single works. A range of methodologies is used, including film studies and musicology, and archival research has informed original readings in various chapters. Some chapters also look at how the stage musical concerned is already an adaptation, e.g from a play or novel. Overall, the book reflects on stage-to-screen adaptations and offers an introduction to the scholarship on the subject, often offering the first-ever scholarship on various important films.
