From film and television theory to intertextuality, poststructuralism to queer theory, postcolonialism to meme theory, a host of contemporary theories in the humanities have engaged with adaptation studies. Yet theorizing adaptation has been deemed problematic in the humanities' theoretical and disciplinary wars, been charged with political incorrectness by both conservative and radical scholars, and declared outdated and painfully behind the times compared to other disciplines. And even separate from these problems of theorization is adaptation's subject matter - with many film adaptations of literature widely and simply declared "bad." In this thorough and groundbreaking study, author Kamilla Elliott works to detail and redress the problem of theorizing adaptation. She offers the first cross-disciplinary history of theorizing adaptation in the humanities, extending back in time to the sixteenth century - revealing that before the late eighteenth century, adaptation was valued and even celebrated for its contributions to cultural progress before its eventual - and ongoing - marginalization. Elliott also presents a discussion of humanities theorization as a process, arguing the need to rethink how theorization functions within humanities disciplines and configure a new relationship between theorization and adaptation, and then examines how rhetoric may work to repair this difficult relationship. Ultimately, Theorizing Adaptation seeks to find shared ground upon which adaptation scholars can dialogue and debate productively across disciplinary, cultural, and theoretical borders, without requiring theoretical assent or uniformity.
