Justin Cheung is a mailroom clerk. But not just any mailroom clerk. He works at the Creative Artists Agency, one of the most powerful and best-connected entertainment and sport agencies in Hollywood. Humble as his position appears, it is highly coveted—both for the insider’s view it provides of the industry, and for the opportunity it gives to make powerful connections. Ultimately he is hoping to follow in the illustrious footsteps of his father, the actor, director, writer and producer Alfred Cheung. With the recent release of Justin’s first lm, Yaya, a documentary that explores the exploitation and abuse of helpers in Hong Kong, he’s already well on his way to doing so.
