Quentin Tarantino was a guest on The Tonight Show with Jay Leno earlier this week, 20 years after his first appearance. He recalled that early nineties visit and, more interestingly, revealed the first details of his possible next film. It is not, as previously expected, Killer Crow, a WWII movie about a "bunch of black troops" and the last entry of Tarantino's so-called historical trilogy (following Inglourious Basterds and Django Unchained).
In the video below, Tarantino instead reveals he is returning the western genre ("but not a Django Unchained sequel") and his current writing process.
