Hong Kong's Ironman stepped up to the plate when Dr. No (1962) took the world by storm in the 1960s. Tso Tat-wah, the quintessential tough guy of Cantonese cinema who had appeared in dozens of popular action films, was licensed to spy in several 007 imitations. Here, he is Agent 303, the lucky number "3" a vivid sign of East-West integration. Presented in glorious widescreen, the film is garnished with secret weapons and ominous hideouts, mind games and technological intrigues, violence and sex, the latter in the form of a silhouette striptease!
