The real person, on which the character of Dan Mahowny is based, is now a consultant for a company that investigates fraud.
The character's name was changed to Dan Mahowny, in part because his real name (Brian Molony) was very similar to the name of the Canadian Prime Minister at the time (Brian Mulroney).
The movie's budget was about $10 million, which was also roughly the amount that the real person on whom Dan Mahowny is based stole from the bank for which he worked.
