UPDATE: According to Deadline, Quentin Tarantino's next film will, indeed, be a western. He's finished the script which, unlike his previous projects like Inglorious Basterds and Kill Bill, "just flowed out of him" (his past screenplays have reportedly taken the auteur years to write). So, there. We can officially be excited about a Tarantino western, which will no doubt be absurd and awesome.
Quentin Tarantino's next film will be a spaghetti western. And, well, we kind of know what the title is.
According to an interview with Franco Nero on movieplayer.it -- combined with a nice Google translation (thanks, Internet!) -- its title will be The Angel, The Bad and The Wise and will be a tribute to Sergio Leone, the famous Italian director known for his work defining the genre.
BadassDigest claims to know other details -- like the cast, plot details, etc. -- but won't offer any of them up, except claiming that it will "blow [our] minds." Oh, really? Sounds awesome, guys. Thanks for the information!
Regardless, it is nice to see that Sally Menke's unfortunate death this past fall hasn't stopped Tarantino from pressing forward in his career. For those unaware, before her untimely death, Menke had been his right hand editor who cut all of the Oscar winner's films. Her work quite visibly contributed to much of their acclaim.
