There's something else going on here. Inglourious Basterds and Django both leaked during pre-production, and that sure didn't stop him. He clearly didn't have a lot of stake in this project. Could also have something to do with Harvey Weinstein's recent "I'm not doing any more violent movies" announcement.

That's a bingo. Those other leaks were all tagged "Last Draft," ready for action. Those were the scripts he was planning to shoot (and did), so they represented a version of the film that he was comfortable going out into the world. This was a first draft, NOT something that necessarily represented the film he intended to finally show audiences.

QT said he's walking away because he sees it as a personal betrayal. Sounds like he suspects Bruce Dern. He went on to say he enjoys when a script leaks later in production - he's flattered by fan interest. He doesn't care about leaks inherently, it seems. Just not when it's an unfinished product and by a friend.

It's a bummer cause it sounded like an awesome project and it was all set to go. Who knows when he'll be done writing the next one, and when THAT one goes into production?

Possible, though not likely. More likely is that he goes back to this script and makes it AFTER whatever his next movie ends up being.

It's particularly a bummer cause good Westerns almost never get made anymore, and this could've been a great one. Pretty much no one except Tarantino has the clout to get a Spaghetti Western made in 2014.

Or Silent Running? Come on... spaceships!

This just in, Quentin Tarantino is suing Gawker for copyright infringement and promoting illegal downloading of the script.
