When 27-year-old George A. Romero set out to shoot his first feature, Night of the Living Dead, he had a little over $100,000 to his name and a cast of unknowns. So he got creative. For locations, he staked out abandoned buildings, reasoning that no one would care if a zombie ripped a hole in the wall. For photography, he chose 35 mm black-and-white film, hoping it would smooth over some of the ad-hoc production’s rougher edges. The blood would be Bosco’s chocolate syrup and the guts would be ham, donated from a local butcher shop.
