In the wake of such recent undead boxoffice breakouts as "28 Days Later" and "Dawn of the Dead," Hollywood Reporter reports Lions Gate Films is fast-tracking its own zombie picture, "Flight of the Dead," for a September start date, sources said. "Flight" follows the tale of two zombies being shipped back to their homeland after they are captured. But when the deadly creatures come unexpectedly to life aboard an airplane, the begin to wreak high-altitude havoc. The project is being developed by Lions Gate Entertainment Corp. chairman Andre Link with John Dunning. The two were partners in Cinepix Film Properties, the precursor to Lions Gate Films, and have teamed on such features as "Buffalo '66" and "The Daytrippers." The original draft of the "Flight" screenplay was penned by Gary Parker and Tom Lavangnino, with rewriting done by Dunning and Lorenzo Orzari. No director is on board "Flight."
