LMD: Probably the best-known name in the film is your queen, Park Shin-hye, who’s practically considered a national treasure in Korea. What was it like to direct her?
LW-s: She doesn’t need direction. She’s really well prepared. Like, sometimes she would amaze me, she would think about all other options, and with the king and queen’s emotional line - I’m not a woman, so there’s some details I can’t catch - and she would say, “I think she would do this,” and “The queen felt like this and that’s why she made this kind of choice.” And I thought about it, and it was very different. Park Shin-hye studied really well and she brought all this different emotional line and she convinced me. And I told her, “You saved the queen.” Because I was being very superficial; like making a very one-dimensional queen and she brought all these details that amazed me.
