This paper studies the film The Lion City (1960) from the perspective of national cinema. The Lion City was made by the Singaporean studio Cathay-Keris and was regarded as the pioneer of the local campaign of “Chinese Language Film within Malayan Culture.”( 改为Malayanization of Chinese-language Cinema?) This paper uses this film as example to analyze the uniqueness and problems of the concept of National Cinema, when applied to Singapore such a Chinese population dominated, multi-race, multi-language (including dialect) society. The essay is consisted of three parts. The first part discusses the general situation of Singapore National Cinema. The second part focuses on the film The Lion City. Particularly, it pays attention to several issues, including the difference between this film and the contemporary Hong Kong films that also depicted Southeast Asia scenery, the reasons why the film repeatedly emphasized and advertised itself as a “Chinese Language Film within Malayan Culture,” how the film promoted the ideology of People's Action Party's contribution to a healthy Singapore society, the moderate left-side revolution ideology from the film director Yi Shui and finally, what are the image and quality of the idealized Singapore youth promoted in the film. The third part notices the phenomenon that after the film The Lion City, the campaign of “Chinese Language Film within Malayan Culture” suddenly stopped. It suggests several reasons and examines certain difficulties in the development of Singapore National Cinema.
