No classic by a long shot, but a far better picture than that awful, awful,
awful English title would suggest. Definitely has nothing to do with that awful, awful, awful U.S. TV show, and it also has no semblance
whatsoever to the American TV show DALLAS, despite Kozo's laboured attempt to work it into his review of the film at LoveHKFilm (as in, "Dallas in the palace"

) From what I've gathered, a more accurate translation of the Chinese might be "A Concubine's Smile" (or maybe "A Smiling Concubine"?) which would have been a much more clever English title considering the devious nature of the characters on screen.
Added a credit gallery here, though the DB entry looks fairly complete at this point:
