Shedding light on the regional scale between the national cinema framework and the planetary perspective, East Asian Ecocinema: Between Nation and Planet argues for the importance of East Asia as a critical space for cinematic ecocriticism. Drawing on the influential work of Sheldon Lu and Jiayan Mi on Sinophone ecocinema, and Tommy Gustafsson and Pietari Kääpä’s transnational approach, the book brings together diverse perspectives that examine ecocinema in both national and transnational contexts. Through promoting inter-East Asian conversations, the essays collectively reveal how films from East Asia can reframe global environmental discourse, decentering Hollywood and expanding ecocinema’s conceptual horizons.
