Each of the heroes represents a different high school type: popular babe (Jordana Brewster), picked-on geek (Elijah Wood), goth girl (Clea DuVall), sensitive jock (Shawn Hatosy), new kid in town (Laura Harris), and bad-boy rebel (Josh Hartnett). The plot isn't much--a basic kill-or-be-killed premise spiked with a healthy shot of paranoia--but Willliamson and Rodriguez do a great job of building the tension slowly but surely. The suspense set pieces are genuinely frightening, and the film pokes fun at itself without deflating its scares; Williamson is a master at shifting gears from comedy to horror quickly and adroitly. The young cast doesn't have a weak link among them (with special kudos to Wood, DuVall and heartthrob-in-the-making Hartnett), and Rodriguez gets maximum mileage from the titular faculty, which includes Jon Stewart, Piper Laurie, Salma Hayek, Bebe Neuwirth, and Robert Patrick of Terminator 2. Go to the head of the class, Mr. Williamson. --Mark Englehart
