This Hong Kong made movie was actually an adaptation of the European spy movie classic, Passport to Hell: Secret Agent 3S3, released in 1965.In that movie, the lead character, Walter Ross, CIA Agent 3S3 (a designation meaning secret agent number 3 of the 3rd Special Division) was played by Georgio (George) Ardisson.Although in this Chinese movie, the lead role was played by Paul Chang, he apparently did not do very well as far as the action sequences & fighting scenes are concerned. He looked suave & flamboyant, but he was certainly no fighter, unlike George.The voluptuous Zhang Zhongwen (Diana Chang), a former Miss Hongkong & considered in Chinese movie circles as Planet Earth's Most Beautiful Animal, added some spice as well as distraction to the movie.The movie title in Chinese (Cantonese to be more specific) was somewhat of a misnomer. Its translation, literally: 'Flamboyant Big Fellow'!
