A film detailing Mrs. Prescott being stalked by Stu and Billy after being contacted by Sidneys half brother. It could have flashbacks to her acting career and then show her affair with Cotton. Stu, Billy and Her brother (his name was Roman, right?) Could be sitting around trying to invent the Ghostface costume and his MO all while committing lowkey murders around town that aren't exactly linked together (as training perhaps) before they kill Sidney's mom. I think it'd be cool, but then again I just love prequels.
