The Routledge Companion to Cult Cinema offers an overview of the field of cult cinema – films at the margin of popular culture and art that have received exceptional cultural visibility and status mostly because they break rules, offend, and challenge understandings of achievement (some are so bad they’re good, others so good they remain inaccessible). Cult cinema is no longer only comprised of the midnight movie or the extreme genre film. Its range has widened and the issues it broaches have become battlegrounds in cultural debates that typify the first quarter of the twenty-first century. Sections are introduced with the major theoretical frameworks, philosophical inspirations, and methodologies for studying cult films, with individual chapters excavating the most salient criticism of how the field impacts cultural discourse at large. Case studies include the worst films ever; exploitation films; genre cinema; multiple media formats cult cinema is expressed through; issues of cultural, national, and gender representations; elements of the production culture of cult cinema; and, throughout, aspects of the aesthetics of cult cinema – its genre, style, look, impact, and ability to yank viewers out of their comfort zones. The Routledge Companion to Cult Cinema goes beyond the traditional scope of Anglophone and North American cinema by including case studies of East and South Asia, continental Europe, the Middle East, and Latin America, making it an innovative and important resource for researchers and students alike.
