Sandra Oh gained fame and fortune for 10 seasons as Dr. Cristina Yang on Grey's Anatomy, but she admitted that this success came at the cost of hiding her Korean heritage. Speaking in a clip from the documentary "The A List: 15 Stories From Asian and Pacific Diasporas," directed by Canadian producer Eugene Yi, Oh recalled being born in Canada as the daughter of Korean immigrants and shared the sensitivities experienced by the show's crew.

Oh expressed that Grey's Anatomy had one of the most diverse casts of its time, yet they avoided discussing it. "Half of our cast wasn't white, which was very important," Oh said, continuing, "We almost got a response like, 'Shh, let's not talk about this. We can just do it and succeed.' 'Oh my God, it happened!' The show, created and produced by Shonda Rhimes, had an approach that shied away from discussing ethnicity back then.

Before reaching stardom, the Canadian producer had roles in Canadian indie films like Double Happiness and The Diary of Evelyn Lau. After moving to Hollywood, she made history by being the first Asian actress nominated for an Emmy for her role as Dr. Cristina Yang, playing a significant part in the success of Grey's Anatomy.

Oh also starred in Killing Eve and has been seen in films like The Princess Diaries and Sideways. In previous statements, it was noted that the Grey's Anatomy writers had to make changes to the scripts for dialogue that suited Oh's character and even assigned her a special "Sandra translator" in the writers' room to address this issue. The documentary will premiere on HBO and HBO Max on May 13.
