Infernal Affairs has received journalistic, popular and corporate notice but little vigorous critical attention. In this book, Gina Marchetti explores the way this example of Hong Kong's cinematic eclecticism have crossed borders as a story, a commercial product and a work of art; and has had an undeniable impact on current Hong Kong cinema. Moreover she uses this film to highlight the way Hong Kong cinema continues to be inextricably intertwined with global film culture and the transnational movie market.
