<Li> Blu as Chips </Li> <P> James Gunn is partially responsible for the screenplay although he received a solo writing credit . After he left the project to concentrate on Scooby - Doo 2: Monsters Unleashed, Michael Tolkin and Scott Frank were brought in for rewriting . In a commentary track on the Ultimate Edition DVD for the original George A. Romero's Dawn of the Dead, Richard P. Rubinstein, producer of the original and the remake, explained that Tolkin further developed the characters, while Frank provided some of the bigger and upbeat action sequences . </P> <P> The mall scenes and rooftop scenes were shot in the former Thornhill Square Shopping Centre in Thornhill, Ontario, and the other scenes were shot in the Aileen - Willowbrook neighborhood of Thornhill . The set for Ana and Luis's bedroom was constructed in a back room of the mall . The mall was defunct, which is the reason the production used it; the movie crew completely renovated the structure, and stocked it with fictitious stores after Starbucks and numerous other corporations refused to let their names be used (two exceptions to this are Roots and Panasonic). Most of the mall was demolished shortly after the film was shot . The fictitious stores include a coffee shop called Hallowed Grounds (a lyric from Johnny Cash's song "The Man Comes Around", which was used over the opening credits), and an upscale department store called Gaylen Ross (an in - joke reference to one of the stars of the original 1978 film). </P> <P> The first half of the film was shot almost entirely in chronological order, while the final sequences on the boat and island were shot much later and at a different location (Universal Studios Hollywood) than the rest of the film, after preview audiences objected to the sudden ending of the original print . </P>
