"We were really lucky with the Scream films to actually make a good trilogy, I think it's very challenging to find other films that have done that properly," she told FilmFocus, "but I think it was a good idea for me to stop there. They are going to go ahead and make a Scream 4, I guess they're casting it right now and it was offered to me; but to me, for Sidney, it just doesn't make sense."
And why the change of heart? Logic, of course. "Sidney Prescott should have gone insane in the second Scream," she joked, "It was hard for them to get me to do the third one; how far can you go with a character whose friends have either all tried to kill her or died? The only way I could be in Scream 4 is in an insane asylum in a straight-jacket."
