Both comics studies and adaptation studies have grown separately over the past twenty years. Yet there are few in-depth studies of comic books and adaptations together. Available for the first time in English, this collection pores over the phenomenon of comic books and adaptation, sifting through comics as both sources and results of adaptation. Essays shed light on the many ways adaptation studies inform research on comic books and content adapted from them. Contributors concentrate on fidelity to the source materials, adaptation and myth, adaptation and intertextuality, as well as adaptation and ideology. After an introduction that assesses adaptation studies as a framework, the book examines comics adaptations of literary texts as more than just illustrations of their sources. Essayists then focus on adaptations of comics, often from a transmedia perspective. Case studies analyze both famous and lesser-known American, Belgian, French, Italian, and Spanish comics. Essays investigate specific works, such as Robert Louis Stevenson's The Strange Case of Dr. Jekyll and Mr. Hyde, the Castilian epic poem Poema de Mio Cid, Ray Bradbury's Martian Chronicles, French comics artist Jacques Tardi's adaptation 120, rue de la Gare, and Frank Miller's Sin City. In addition to Marvel Comics' blockbusters, topics include various uses of adaptation, comic book adaptation of literary texts, narrative deconstruction of performance and comic book art, and many more.
