I meant to put this up when it first happened, but I'll throw it up now, as an amusing aside - the daughter of a friend of ours recently got to act as interviewer to the folks who are making the film(s) of the Dark is Rising books. She was flown to Romania and spent a couple days interviewing people. You can read the details over at Derek's blog and the article in French.
I don't know about the rest of you, but I read these books when I was 11 or so, and loved them, so I was pretty excited to see they were making films (though, as always, concerned they were going to screw it up). It's even more fun now.
