"DR. Strangelove," Stanley Kubrick's 1964 film about nuclear-war plans run amok, is widely heralded as one of the greatest satires in American political or movie history. For its 40th anniversary, Film Forum is screening a new 35 millimeter print for one week, starting on Friday, and Columbia TriStar is releasing a two-disc special-edition DVD next month. One essential point should emerge from all the hoopla: "Strangelove" is far more than a satire. In its own loopy way, the movie is a remarkably fact-based and specific guide to some of the oddest, most secretive chapters of the Cold War.

As countless histories relate, Mr. Kubrick set out to make a serious film based on a grim novel, "Red Alert," by Peter George, a Royal Air Force officer. But the more research he did (reading more than 50 books, talking with a dozen experts), the more lunatic he found the whole subject, so he made a dark comedy instead. The result was wildly iconoclastic: released at the height of the cold war, not long after the Cuban missile crisis, before the escalation in Vietnam, "Dr. Strangelove" dared to suggest -- with yucks! -- that our top generals might be bonkers and that our well-designed system for preserving the peace was in fact a doomsday machine.

What few people knew, at the time and since, was just how accurate this film was. Its premise, plotline, some of the dialogue, even its wildest characters eerily resembled the policies, debates and military leaders of the day. The audience had almost no way of detecting these similiarities:Nearly everything about the bomb was shrouded in secrecy back then. There was no Freedom of Information Act and little investigative reporting on the subject. It was easy to laugh off "Dr. Strangelove" as a comic book.

But film's weird accuracy is evident in its very first scene, in which a deranged base commander, preposterously named Gen. Jack D. Ripper (played by Sterling Hayden), orders his wing of B-52 bombers -- which are on routine airborne alert, circling a "fail-safe point" just outside the Soviet border -- to attack their targets inside the U.S.S.R. with multimegaton bombs. Once the pilots receive the order, they can't be diverted unless they receive a coded recall message. And 0nly General Ripper has the code.
