If you're a fan of this movie--and who isn't?--you might want to check out the new anthology Forbidden Planets, in which about a dozen writers (including me) offer wildly varying but universally interesting takes on the central ideas raised by the film. Or something like that.
I mentioned this before; the difference is that the book is actually out now. My contribution is called "This Thing of Darkness I Acknowledge Mine," which, yeah, is a line from The Tempest. There are times, and this is one of them, when you should go ahead and wear your influences on your sleeve.
