"Hill was carrying a Thompson submachine gun as we walked. A retired Air Force officer, he’s the film’s weapons coordinator, but he really likes being a zombie. “This is supposed to be a horror movie,” he said, “but it’s also an action thriller It’s a whiz-bang. We’ve fired thousands of rounds of blanks; every type of weapon available. “Now, let me tell you about being a zombie, When you go into your zomb, you’re in a fantasy. I go into the role feeling I am the living dead, I can’t focus on things, I can’t get it together. I researched it in books – the wide-open eyes, the clutching hands, the slow movements. Then I made my own zombie. I asked George and he said, ‘Be your own zombie.’ I intend to be the best zombie there ever was. I want people to come away from this movie saying, ‘Wow, he was a good zombie.’ Sharon, the nurse zombie, got into her zomb so heavily the other night, she made herself sick. We’ve got some good zombies. When we were shooting the exteriors and it was zero degrees, there was this 300-pound guy showed up every night in a bathing suit. He said, ‘I’m not cold. I love it.'”"
