KoreAm Journal - August 2005 List
Extract from Sandra Oh feature / interview:
And then she continues talking, calling it an impossible question because she doesn't have perspective other than her own experience, and then, she is interrupted by co-star Katherine Heigl, who plays the soft-hearted Dr. Izzie Stevens.

Heigl stops by to say goodbye, but then the subject comes up that Heigl's older sister is a Korean adoptee. Heigl is excited to learn that Sandra's guest is also adopted and a discussion is born about birthparent searches.

Before Heigl leaves, she offers a quick sound bite about Sandra. "She makes my performances better, which is always nice. It's just a really amazing work experience. She's super talented, super cool. We're good friends. It's just been a dream come true."
