Something becomes real—to those who are elsewhere, following it as “news”—by being photographed. But a catastrophe that is experienced will often seem eerily like its representation. The attack on the World Trade Center on September 11, 2001, was described as “unreal,” “surreal,” “like a movie,” in many of the first accounts of those who escaped from the towers or watched from nearby. (After four decades of big-budget Hollywood disaster films, “It felt like a movie” seems to have displaced the way survivors of a catastrophe used to express the short-term unassimilability of what they had gone through: “It felt like a dream.”)
