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.
Hate to say it but you'll be real disappointed in the movie if you liked the book! I read it with Alex in the week before she went off to Roumania and very little of the story line ended up in the film - they even cut out the "Walker" character when editing the film despite leaving him in the movie poster. "Lovejoy" was the only actor to have fun camping the butler...
