The film is unusual in that although featuring Sammo Hung and Lam Ching-ying , two actors famed for their kung fu abilities , neither actually perform any martial arts . Golden Harvest had wanted Hung to perform fight scenes in the film , but he refused , rationalising " My character was mentally retarded , mentally disabled , so how can you ask me to fall down and suddenly become well again ? And fight ? They knew my fighting skills and wanted me to be part of the action but I thought that would have completely destroyed the tone of the film , the principles behind the film . " The action is left to Chan and his fellow CID officers , Mang Hoi , Yuen Wah , Peter Chan and Corey Yuen . Despite the relative lack of action scenes , the film was nominated for the Best Action Choreography award at the 5th Hong Kong Film Awards in 1986 . It was beaten by Chan 's '' Police Story ''
