He also mentions Mischa specifically in this quote:
In particular, Mischa Barton is a joy to work with, and her eyes are so expressive–she reminds me of a silent film actress. I also feel great sentimental attachment to her as she was one of the first people I worked with when I started directing on THE O.C.
