This book studies British literary writers’ engagement with adaptations of their work across literary, theatrical, and film media in the nineteenth and early twentieth centuries. It considers their critical, reflective, and autobiographical writings about the process of adaptation, and traces how their work was shaped, as well as delimited, by their involvement with adaptations to different media and intermedial writing. Linking canonical and non-canonical writers both chronologically and contemporaneously, and bridging studies of prose fiction adaptation from nineteenth-century theatre to early twentieth-century film, this book offers an interdisciplinary, transhistorical, cultural, and analytical study of adaptation and the variable positions of writers within and across media.
