If you read the original script from HoDS, quite a few pivitol scenes were not in the movie. For example: watching the movie, Barnabas and Willie were having an argument regarding Barnabas' wanting to get Jeff Clark out of the way (well, who wouldn't?). Willie asks Barnabas if he's going to do something to Jeff; Barnabas replies, rather, he's going to do something for him. And then Jeff's gone (well, not that that's a bad thing), no explanation. Turns out there was a scene, maybe a couple, I don't recall exactly now, in the script in which Barnabas has made arrangements for Jeff to have a gallery showing of his works somewhere out of town, or something like that, so Barnabas can spend time wooing Maggie. There are other various scenes which fleshed things out more that didn't make it to the big screen.
