"If I were to wait only for roles that clarify my racial makeup, I'd be waiting for a very, very long time"

In this quote, Wentworth Miller is expressing his disappointment with the absence of diverse functions in the entertainment industry. He is acknowledging that as an individual of combined race, it is rare for him to find roles that properly represent his racial identity. Miller is suggesting that if he were to restrict himself to only accepting functions that specifically require his racial background, he would be badly limiting his chances as a star. He recognizes that this is a typical struggle for stars of varied backgrounds and acknowledges that it might be a long period of time before the industry becomes more inclusive.
