Attila Ambrus invented himself. Fleeing the oppressive Ceausescu regime (especially repressive to Hungarians of Transylvanian extraction, stranded in Romania as a result of borders redrawn following two world wars), Ambrus arrived in Budapest at a critical moment: the juncture of the ebbing of Communism in Hungary, and the arrival of a particularly shambolic form of Hungarian free enterprise. The man was very much a product of his time.
Purely through personality and force of will, Ambrus landed a spot (as Zamboni operator and third-string goalie) on UTF, which had been Budapest's premiere hockey franchise. From there he found a career as a pelt smuggler, which led him (as the result of a horrific Tunisian holiday) to his true vocation, that of bank robber. It would not be too much of a stretch to see him as a post-modern Robin Hood, a redistributor of wealth from the institutions of a corrupt State, and the travel industry which had betrayed his dreams, into the hands of casino owners, bar owners, drug dealers, and prostitutes (or at least their pimps). As a bank robber, he evinced a brilliant tactical mind, but a weak strategic grasp. What is certain is that he became a national hero, or if not exactly a hero, then like The Dude, the man for his time.
As far as I know, there is no movie in the works retelling the saga of the Whiskey Robber; I feel that Ambrus would make an ideal subject for either a Guy Ritchie feature, or a Werner Herzog documentary.
