Film fans love to scrutinize the works of their favorite directors, and Quentin Tarantino devotees are no different. Many supporters enjoy checking all the details of the director's works and seem to assume they all exist in the same universe.
For instance, Michael Madsen's character in Reservoir Dogs is named Vic Vega, while John Travolta's is called Vincent Vega in Pulp Fiction. Many characters smoke fictional Red Apple cigarettes, and many names, such as "Alabama," crop up in backstory and expository dialog from time to time.
The latest comments from Tarantino don't necessarily indicate that there's any credence to these theories, but they do shed some light on where his next movie might go.
According to IndieWire, the filmmaker recently mentioned that Inglorious Basterds and the upcoming Django Unchained "bespeak a trilogy." This probably means that whatever he makes next will probably be a genre exercise, following in the footsteps of Basterds' war epic and Django's Western. Some rumors from the past include a spy movie or a prohibition-era gangster picture, both of which would be fantastic.
