Speaking with talk show host Oprah Winfrey, Rhimes said: "Cristina was second, simply because she's the kind of woman I know really well, and I like her . There's something interesting about a person who is that driven, a little bit emotionally disconnected but still a caring, sweet, and smart individual you could be friends with ." Sandra Oh, initially auditioned for the character of Bailey, adding: "Thank God I did not get that part", explaining the show would not be the same without fellow cast member, Wilson . Discussing casting Oh as Yang, Rhimes said: "She brought this energy that felt very fresh . From the beginning, I've been shaping Cristina around Sandra a little bit . One of my favorite things to do is take as much of her dialogue out of a scene as possible because she does so much nonverbally . Then I just watch what she manages to do without having a word to say ." </P> <P> The character of Yang was not originally supposed to be of Asian descent .

Online reported in May 2012, that Oh, as well as all original cast members, had signed on for two more years . </Dd> </Dl>
