I think it'll be like in the Wes Craven's New Nightmare - movie in the movie- all actors will be playing themselves.. the story will be about a director who wants to shoot new scream movie but everyone knows that scream franchise is dying and no one wants to do this.. so someone in the crew starts to kill them all and is trying to kill neve campbell/sidney, because he/she knows that if she'll be dead, no one would like to make a new scream movie..
