Karen's friend Maggie (RIP) learned this lesson the hard way, literally, when Chucky snuck up on her (and us) in Andy and Karen's apartment with a hammer. It's one of the biggest and best jump scares in the entire franchise, and of Child's Play's pivotal scenes. Because once that hammer hits Maggie's face, and sends her falling out of the kitchen window and onto a truck, the movie kicks into full slasher flick overdrive.
So it falls to these same companies to build something for the studios that will be rather harder and more persuasive, to act as a hurdle against piracy for these new DVDs. In fact an organization called Advanced Access Content System (AACS), formed back in July by such notables as IBM, Intel, Microsoft, Panasonic, Sony, Toshiba, Disney and Warner Brothers has come together in order to create a decent speed bump against piracy that should last at least for the next decade, a decade during which broadband lines improve to the point where it will be child's play to download even a high definition movie. 2b1af7f3a8
