Bernard Madoff may go down as one of the biggest stock market fraudsters ever.

But even if the losses from the New York fund manager’s Ponzi scheme reach $50 billion—Madoff’s own estimate—he will remain a bit player in the ongoing market collapse.

But not all $50 billions are alike. For Lehman Brothers, which once had that much market capitalization, the sum supported a balance sheet many times larger. For Madoff, the effect of the loss will be magnified in a different way—by wounding the trust on which financial markets are built. Too many Madoffs and the whole financial would collapse.

The psychological drama of con men has entranced many writers: Herman Melville, Charles Dickens, Thomas Mann and John le Carré. The authors, like the dupes, have often been seduced by the fraudsters’ almost magnificent ability to take advantage of human weakness.

In retrospect, Madoff looks anything but magnificent—more like a schemer, or perhaps a foolish man caught up in a fast-expanding web of lies. But for many years, he was able to charm many rich people who should have known better.

That ability and the calibre of the victims mean that Madoff’s bit part in the financial crisis could easily translate into a major motion picture. A clever director will give the audience the satisfaction of seeing the villain unmasked and punished. But the film is likely to linger on the years of dishonest glory. Deception is dangerous, but it comes with a certain glamour.
