Selling Hitler (1991)

In 1981, Gerd Heidemann, a bloodhound reporter for the German magazine Stern, believes he's stumbled onto the greatest literary find of the century: the personal diaries of Adolf Hitler. Shrouded in secrecy, Heidemann and the men of Stern attempt to pull off the greatest scoop in publishing history, blinded by their greed to the fact that the diaries are, in fact, crude forgeries.
