Sorry if I upset you and Midnite by posting the link, MB. I didn't think the spoilers were all that much beyond what is stated in the official synopsis released long ago by TPTB, but perhaps you've even avoided reading that. I seem to lack the faculty for being spoilt--or even understanding what is meant by "spoiler," and I do try to play it safe here.
Warner Brothers stalled Dan Curtis for years. I don't care what anybody tells you, the young execs did not want Curtis, they just wanted to do their own thing with his intellectual property. They muscled him out, and then they waited until he died so that they could turn Dark Shadows into a Tim Burton franchise. And they will relish the moment that their "grandmother's generation" reacts to the put-down. That's the sort of people they are at Warner Brothers.
As I understand it, making the DS movie wasn't any Warner Bros. execs' idea, it was Johnny Depp's. Johnny Depp was the one who wanted to make the movie, and ended up at Warner Bros. It was Johnny, not Warner, that wanted Tim aboard, wasn't it?
