"Somewhere else in this house," Tony says, "is a cabinet full of 25,000 library cards, three inches by five inches. If you want to know what Napoleon, or Josephine, or anyone within Napoleon's inner circle was doing on the afternoon of July 23 17-whatever, you go to that card and it'll tell you."

"Who made up the cards?" I ask.

"Stanley," says Tony. "With some assistants."

"How long did it take?" I ask.

"Years," says Tony. "The late 1960s."

Kubrick never made his film about Napoleon. During the years it took him to compile this research, a Rod Steiger movie called Waterloo was written, produced and released. It was a box-office failure, so MGM abandoned Napoleon and Kubrick made A Clockwork Orange instead.

"Did you do this kind of massive research for all the movies?" I ask Tony.

"More or less," he says.

"OK," I say. "I understand how you might do this for Napoleon, but what about, say, The Shining?"

"Somewhere here," says Tony, "is just about every ghost book ever written, and there'll be a box containing photographs of the exteriors of maybe every mountain hotel in the world."

There is a silence.

"Tony," I say, "can I look through the boxes?"
