Leaving Hollywood and heading to London today for one of the most famous Crew stories involving Set P.A.s in very wide lockups. 28 Days Later didn’t have the resources to shut down huge areas of London in order to film its opening moments, which feature Cillian Murphy wandering through deserted streets after waking up from a coma one month after the rage virus apocalypse. It was important for Danny Boyle to make the city look empty, which seems impossible in one of the biggest metropolitan areas in the world. The shots didn’t use any CGI, but were achieved using the simple technique of waking up extremely early. The crew needed to begin work in the early hours of the morning to dress the streets in the dark before dawn. They would set the lockups as dawn was breaking and as soon as there was usable light, start filming before the city got too busy to hold people and cars back. Because the film used low-grade digital cameras, the crew could gather footage quickly, and the early morning hours provided an eerie silence that makes the sequence so chilling.
