The film poster says "Six million dollars says they won't find Harry by Midnight". However in the movie, 'Steve' (played by Bryan Brown) actually says that unless they find Harry by midnight the amount at stake is six million POUNDS, which in 1984 equated to between 8 and 9 million US dollars.
During the flashback where Paul remembers Harry leaving, with great fanfare, for the Broadstreet Station (tapes in hand) there is a crew member's head poking out from behind the grand staircase, right side.
