Visible crew/equipment: In the first scene of the Christmas party when Takagi steps out of one the offices and greets a couple of his guests, the camera pans left to show the orchestra and other guests. A huge shadow of the camera and its operator is being shown on the back wall, then the stage light gets moved to light a different area and the shadow is gone. (00:02:20)
Question: Why didn't Hans Gruber simply place 5 hostages in a room and threaten to blow their brains out if John McClane doesn't hand himself in? John McClane is the good guy with a conscience and Hans Gruber is the ruthless killer that kills 2 people in a heartbeat, John would have been forced to hand himself in or be responsible for their deaths. Even if Hans didn't want to kill anyone, he could have pretended to shoot people one by one. John wouldn't know any better.
