After four months of restless waiting, filmmaker Kiwi Chow received a dreaded, but not altogether unexpected, message: Hong Kong censors had banned his new movie from reaching the big screen.

The 46-year-old¡¯s career, which took off in 2015 with an award-winning dystopian tale, encapsulates how a film industry once known for its audacious spirit and sardonic humour has dimmed to leave artists describing a creative straitjacket.

His latest thriller ¡°Deadline¡± tells the story of an elite school rattled by warnings of an impending suicide, Chow said in an interview on Wednesday, describing the work as an allegory for hyper-competition under capitalism.
