According to director Tor Ramsey, he was pressured a lot during the filming by Karen L. Wolf and John A. Russo, who made him use their friends as the film crew even though Ramsey wanted to hire other people. After screening the Directors Cut of the film, Wolf took the film away from Ramsey, hired a new editor and even looped many lines to correct the plot holes of the new cut.
Tor Ramsey had intended to get an acquaintance of his - an award winning DOP who had worked with MTV - to come aboard. But he was told he had to use John A. Russo's friend Bill Hinzman, who had shot a number of George A. Romero's early films, but had only worked on two films since then.
Sheriff Randolph gives Matt and Laurie the history of zombie activity in the diner. He says the first outbreak was in 1969, referring to Night of the Living Dead (1968). He then says the second outbreak was in 1986, referring to The Return of the Living Dead (1985).
Karen L. Wolf stayed on set and threatened to fire anyone who questioned her script. When actors protested that the lines didn't make sense and wanted to work through their scenes, Karen refused to allow any changes to be made.
A workable Director's Cut was created which cut down the long dialogue scenes and emphasised the action scenes. However Karen L. Wolf fired everyone in Pittsburgh, hired a new editor and re-cut the film. She reinserted long dialogue scenes and looped even more dialogue without the director, resulting in robotic delivery of many of the lines.
