There's a maddening article by Ursula LeGuin in the Slate archives about how the SyFy (then Sci Fi) channel manhandled, eviscerated, and perverted her Earthsea books. Initially I was excited to see that they'd even done a series, but now I mourn an opportunity squandered.
When I looked over the script, I realized the producers had no understanding of what the books are about and no interest in finding out. All they intended was to use the name Earthsea, and some of the scenes from the books, in a generic McMagic movie with a meaningless plot based on sex and violence.... My color scheme was conscious and deliberate from the start. I didn't see why everybody in science fiction had to be a honky named Bob or Joe or Bill. I didn't see why everybody in heroic fantasy had to be white (and why all the leading women had "violet eyes"). It didn't even make sense. Whites are a minority on Earth now—why wouldn't they still be either a minority, or just swallowed up in the larger colored gene pool, in the future?....Instead of a mostly non-white cast that was faithful to the books, the producers hired just two non-white actors, one of them an extra. She also talks about previous issues she had with book covers:
I had endless trouble with cover art. Not on the great cover of the first edition—a strong, red-brown profile of Ged—or with Margaret Chodos Irvine's four fine paintings on the Atheneum hardcover set, but all too often. The first British Wizard was this pallid, droopy, lily-like guy—I screamed at sight of him. Gradually I got a little more clout, a little more say-so about covers. And very, very, very gradually publishers may be beginning to lose their blind fear of putting a nonwhite face on the cover of a book. "Hurts sales, hurts sales" is the mantra. Yeah, so? On my books, Ged with a white face is a lie, a betrayal—a betrayal of the book, and of the potential reader.
