The first Taiwanese-language spy film produced in Taiwan, The Best Secret Agent is a remake of the 1945 movie of the same name that caused a sensation in Shanghai. Fueled by a dog-eat-dog plot and the changing faces of the “female spy” protagonist, the film has been likened to a Taiwanese version of the 007 movies. The film broke box office records in Taiwan and kick-started the popularity of Taiwanese-language spy movies for years to come.
