Through in-jokes, cameos, and simply borrowing footage, some movies have formed unexpected weird connections with other totally unrelated movies. For example...
“Django Unchained” is a prequel to "Shaft"
Quentin Tarantino secretly fashioned “Django Unchained” as a prequel to a ‘70s classic. Attentive viewers may remember that Django’s wife Broomhilda bears the surname “von Shaft”-- well, according to Tarantino, his intention was to infer that John Shaft from “Shaft” is a descendent of Django and Broomhilda. Of course, the reference is subtle, so no intellectual property lawyers told Tarantino to shut his mouth for just talkin’ ‘bout Shaft.
“Casper” implies a depressing fate for the Ghostbusters
The 1995 children’s fantasy/vaguely necrophiliac love story, “Casper,” features a cameo from Dan Aykroyd as Ray Stantz of the Ghostbusters. Depressingly, Ray seems to bust ghosts solo now, appearing in a professional capacity completely alone. So where are the other Ghostbusters? Are they dead?
