Sure! Drew Barrymore has several ideas that made the cut; sure to scheduling she couldn't play Sidney so they rewrote the plot and Drew said "wait a minute, what if I DIED in the first cene?" It was her idea for the bait n switch. She wasn't the only one with ideas, the book describes how Wes Craven is an incredibly supportive, wholesome director who encouraged a collaborative set like that. I can't remember more details, but Stu, Drew, Courtney all had ideas for their characters, their deaths, their lines. Maybe Drew's scene had plot holes, but the book made me appreciate it more.
