Since the 1970s, though, cultural imperialism has been put forward and sparked a series of discussions, yet under the background of globalization, cultural imperialism has exerted more and more significant influence on the film industry of various countries. The impact of Western media flow on the film industry of other countries has long been hard to ignored. As the homogenization of the film industry has become a global problem, this paper further studies the role of cultural imperialism in the global film industry by discussing the origin of cultural imperialism and its development in the context of globalization. Both positive and negative influence of cultural imperialism on the film industry will be addressed. The article will take the response of the film industry in non-Western countries to cultural imperialism as the starting point to explore the possibility of the heterogeneity of the film industry under the influence of cultural imperialism.
