On the back cover of Scream 3 in the Scream trilogy on DVD, the town of the original killings is referred to as Greensboro twice. The correct name of the town is Woodsboro, of course.
And again in this movie there's a small part for the man himself, Wes Craven. He's the guy with the video camera walking by Jay and Silent Bob. He even takes a good look at the camera.
