Political emotion has become one of the most significant components of the ensuing crisis in Hong Kong since it was taken over by China in 1997. By focusing on the highly controversial film Ten Years which was awarded the best film at the 35th Hong Kong Film Awards but heavily criticized for its poor artistic value and intense political implications, this article explores a range of affective cultural practices of fear generated by the film and their social effects on Hong Kong’s post-Umbrella movement era. Informed by the perspective of critical cultural studies, the article examines how this political film offers a site of political intervention through which to perform the politics of fear. The article further illustrates how such emotional politics engages with subject formation in the changing political context, and how it produces a site of political intervention against China. Moreover, the article also elaborates what possible dilemma may be evoked by such politics of fear in relation to Hong Kong’s nativism.
