Speaking to the Telegraph, Tarantino added that he's still going to make his World War II film, Inglorious Bastards, for which he'll be ripping off The Dirty Dozen, then move on to imitate some kind of spaghetti western but set in the slavery-ridden south, allowing the director to possibly throw in some cool blaxploitation shit, too (maybe Pam Grier as a sexy, badass slave escaping her rapist captors, like The Big Bird Cage with more social commentary).
With these three projects on the table, and Tarantino often taking years between movies, it may be as long as a decade before we hear another announcement for a new film, but I'm willing to speculate whatever it is will be something imitating some other stuff from the '60s or '70s, possibly involving kung fu or badass babes, and star.... Patrick Swayze? Maybe Billy Dee Williams? Something like that. And, despite myself, I'll still think it's kind of awesome."
