Hong Kong Directors in Mainland China is one of the very few English-language academic monographs that discuss this film genre at length.It is the third in Chu's "Hong Kong Studies" series of single-authored books devoted to the city's popular culture, including its cinematic culture, in the post-handover era.The previous ones were Lost in Transition: Hong Kong Culture in the Age of China (State University of New York Press, 2013) and Found in Transition: Hong Kong Studies in the Age of China (State University of New York Press , 2018).Unlike these two books, focused mainly on Hong Kong and the consequences of its 1997 sovereignty transfer to China, Main Melody Films explores how, in the 2010s, established Hong Kong filmmakers adapted their filmmaking practices to a new film industry environment in mainland China under new political-economic conditions in China, Hong Kong and elsewhere.These developments were enabled, among other factors, by the Mainland and Hong Kong Closer Economic Partnership Arrangement, concluded in June 2003 between the authorities of the PRC and the Hong Kong Special Administrative Region government, an agreement which allowed Hong Kong film professionals to tap into the profitable audience market of mainland China.As the author indicates, Hong Kong filmmakers were commissioned by either the mainland Chinese authorities or China-based film companies to make "main melody films" (which Chu calls "main(land) melody films" in order to distinguish them from similar films made by mainland film directors).These "main melody films" produced in China, which are essentially propaganda works, have a long mainland tradition, but this tradition may not have been easily accessible to the Hong Kong filmmakers in the 2010s.Nevertheless, as Chu convincingly argues, the filmmakers in question helped extend Hong Kong's film culture to the mainland when they were employed to modify "main melody films" to make them more profit-oriented, entertaining, diverse and "blockbusterised" (pp.2-3, 219).According to Chu, the making of "main(land) melody films" may be understood as a kind of "tactic" (p.47), whereby these filmmakers juggled between the cultures and politics of Hong Kong and the mainland (p.3).The result was a win-win situation: 1) while Hong Kong may have thus lost some established filmmakers to the mainland Chinese film industry, these individuals achieved what they were commissioned to do, sustaining their personal ways of making films in the genres they are good at, while also profiting financially from the mainland audience market; 2) main melody films became more appealing to mainland Chinese viewers.Chu's aim is to provide persuasive cases by discussing some representative "main(land) melody films" created by established Hong Kong filmmakers; the author thereby furthers his theoretical paradigm of Hong Kong Studies.It is a new strand of research that could be grouped under the larger fields of Chinese studies and area studies, and may also establish dialogues with other arts and humanities disciplines, such as film and media studies, cultural studies, literary studies, etc.To support his argument, Chu persuasively examines six Hong Kong filmmakers and their commercially successful and critically acclaimed "main(land) melody films."Placing their cases into
