-Session 9 has some great extras, the best being a short behind the scene's feature that has some great high def video and photo of the old Danvers State Hospital, as well as the actors talking about what it was like to be in the building, and the differe emotions that just being in that building created. It also has some great deleted scenes that should have never been deleted, but they explain why they were deleted. The soundtrack to this movie is also great, it is not music or sound effects per say, it is really one of a kind, could be used in a haunt.
The Mummy Returns has a great extra with a tour of Universal Studios "Chamber of Doom" attraction
Those are a few!
The secret of life is to appreciate the pleasure of being terribly, terribly deceived.
