With the flow of capital and the development of technology, migrant workers are spreading everywhere in the world with the hope of realizing a promising future. However, there is less and less opportunity for stability and for attaining good life, especially in the neo-liberal globalization. Drawing on Lauren Berlant’s explication of people’s attachment to compromised conditions of possibility which constitute the origin of “cruel optimism”, this paper deals with two most issues in migrant workers―their living conditions in the host country and interactions with locals. Through a case study of two Korean films He’s on Duty and Where is Ronny? featured by their representation and narrative of migrant workers, it examines the configuration of migrant workers in these two Korean films around the year of 2010, and how their fantasy for a better life in more developed foreign countries is broken by local anti-foreigner Koreans and social hierarchy. Ultimately, it argues that by incorporating local Korean people into the life of migrant workers, migrant’s optimism can become less cruel and multiracial hybridity becomes possible.
