If Quentin Tarantino won't make The Vega Brothers, other people will, damn it
While not as vast as, say, Stephen King’s interconnected web of stories or Kevin Smith’s View Askewniverse, the films of Quentin Tarantino contain enough threads to reveal that they exist in the same universe. Take the Vega Brothers, Vic and Vincent, who were played, respectively, by Michael Madsen in Reservoir Dogs and John Travolta in Pulp Fiction. They never meet, but Tarantino has confirmed that, yes, they are brothers and that his idea for a Pulp Fiction sequel was to tell a prequel story about their adventures in Amsterdam (where they call it a Royale With Cheese, et cetera, et cetera).
