Early in Die Hard, we are introduced to the businessman Ellis in a scene in which he snorts coke in Holly Gennaro's office.
Later in the movie - in what turns out to be his final scene - Ellis is in Holly Gennaro's office again, this time with Hans Gruber. At one point, one of Hans's men offers a can of Coke to Ellis, and then pours it into a drinking glass.
Is it just a coincidence that Ellis appears with coke in his first scene, and then appears with Coke in his final scene? If not, what is the meaning?
