Codename Cougar also known as Codename Cougar, Operation Cougar or The Puma Action is a 1989 Chinese thriller film. It was codirected by Zhang Yimou and Yang Fengliang. Unlike the bulk of Zhangs early works ranging from 1986s Red Sorghum to 1995s Shanghai Triad, which were all historical pieces, Codename Cougar is a modern thriller involving a skyjacked airliner and political intrigue.
The film follows a commercial airliner on a routine flight between Taipei and Seoul that is hijacked and taken to mainland China by the fictional Taiwan Revolutionary Army Front. Communist authorities cannot seize the plane because of the presence of an important business figure on the flight, and agree to cooperate discreetly with Taiwanese authorities to defuse an already tense situation.The film is generally considered a failure or a footnote to Zhangs general oeuvre Time referred to the film as Zhang Yimous last purely frivolous work. ........
