Okay, I'm sure I'll get a lot of people telling me that I'm wrong, but here goes. When Sidney is running from the killer on the studio set of her own house, she runs into her bedroom. On the wall is a poster of the rock band Creed, who I believe were the producers of Scream 3's soundtrack. But remember, the movie they are filming, Stab 3, is supposed to be set in Sidney's hometown at the time of the ORIGINAL murders. Now, the first Scream movie was released some time in 1996, and Creed didn't release their first album until August of 1997. So how'd she get that poster? If they were trying to be accurate, they would have put up a Pearl Jam or Stone Temple Pilots poster to represent Sidney's high school years!
