No Overflix. In 1966, Connie Chan Po-chu and Josephine Siao Fong-fong starred in multiple contemporary films, cementing their onscreen persona as virtuous young women while becoming the hottest youth idols of their time. Colourful Youth remains the only contemporary film to feature both of them. Filmed in Eastmancolor, the song-and-dance spectacle keeps its fingers on the pulse of its era and presents the vigour of the modern times.
