 The two scenes in which Marcos Woinski delivers the money in the  mailbox were not scripted. In the original screenplay there was only  one delivery scene and it took place on a parking lot, with  Mendizabal (Federico Luppi) behind the wheel of his car, and the  delivery guy throwing the envelope in his car. The original ending  (in the original screenplay)was supposed to be only the close shot  of the curtain in Mendizabals room with the three cigarette burns.  And the ending seen in the film (the one with Kulpe picking up his  money from the mailbox) was scripted at the last minute and filmed  right after the Mendizabal Pick up.
