The return of Cantonese really took off with the comedies of former TVB stars the Hui Brothers (actor-director-screenwriter Michael Hui, actor-singer Sam Hui and actor Ricky Hui). The rationale behind the move to Cantonese was clear in the trailer for the brothers' "Games Gamblers Play" (1974): "Films by devoted young people with you in mind." This move back to the local audience for Hong Kong cinema paid off immediately. "Games Gamblers Play" initially made US$1.4 million at the Hong Kong box office, becoming the highest-grossing film up to that point. The Hui movies also broke ground by satirising the modern reality of an ascendant middle class, whose long work hours and dreams of material success were transforming the colony into a modern industrial and corporate giant (Teo, 1997). Cantonese comedy thrived and Cantonese production skyrocketed; Mandarin hung on into the early 1980s, but has been relatively rare onscreen since.
