Meta References in Dramas

  I love meta references, and there are so many in asian dramas. They're like little easter eggs for me to treasure. The Hong Sisters are especially well-known for being self-referential, but there are many meta allusions out there, from actors discussing getting their own autograph to clips from related shows. There's even the more subtle and ubiquitous question "Are you writing/starring in/filming a drama?" Here is an open-ended list:

The King 2 Hearts Review

  This drama is packed with great stuff—romance, political intrigue, comedy, action, and frankly some of the best non-asian actors I've seen in a kdrama. (Most of them aren't actually good actors, but most "foreign" actors I've seen in kdramas have been terrible, and these actors are somewhat decent. . . mostly.)
  One of my favorite aspects of this drama is Ha Ji Won's character Kim Hang Ah. She's a tough-as-nails North Korean drill sergeant who has to deal with South Korea's crown prince/Peter Pan/playboy Lee Jae Ha (in a world where South Korea has a nominal monarchy). Are we surprised that Ha Ji Won is playing a tough chick? Not in the least, because she's awesome at it, but this girl has a squishy center.
