In my original story for Scream 3, the killers were basically a fanclub of Woodsboro kids that had formed because of Stab 1 and Stab 2… They were all doing the killings and the big surprise of the movie was when Sidney walked into the house after Ghostface had killed everyone … and they all rose up. None of them were actually dead and they’d planned the whole thing.

The motive was their quest for fame, so I just placed that into one character with Scream 4… They were trying to top [Sidney’s] Woodsboro story so they could be the legacy of their hometown. All those ideas metamorphosed into The Following.
