Johnnie To teams up with Sylvia Chang to bring the latters play to the big screen in Office! In 2008, Chang & stage director Edward Lam debuted Design for Living in Shenzhen. Written by & starring Chang herself, the play went on to run another 82 shows to massive acclaim. Towards the end of its run, Chang began bouncing around the idea of adapting the script to film as a musical, & the wheels were set in motion when To expressed interest in directing. The partners then assembled a truly star-studded cast in Eason Chan, Chow Yun Fat & Tang Wei, as well as newcomers Wang Zi Yi & Lang Yue Ting. For the all-important music, Chang & To enlisted the efforts of the iconic Luo Dayou.
Lee Seung (Wang Zi Yi), newly hired at Jones & Sunn, enters the billion-dollar company with all the hope & bright-eyed idealism youth affords. However, he soon finds that this new world is much more complicated than he first thought, with a myriad of illicit relationships, including one between the company chairman (Chow Yun Fat) & the CEO (Sylvia Chang), & the cutthroat world of finance laid bare before his eyes as Jones & Sunn prepares to go public.
