What?
What are specific rumors about writing in a random blog, I don't get what this means.
The author is at awardswatch forums, he read about the Cohen's MacBeth and this being rejected by the Venice Festival, next he make those rumors.
It's ridiculous to think that Netflix had no idea about this old script or the book, And a script that many people have even had for years (I haven't finished reading it), plus let's not ignore that Netflix has a bunch of gory and x-rated stuff in its libraries. Some people think those huge executives are 6 years old, I don't believe it.
The problem that I could see is if Netflix is aiming for this to be an Oscar bait and crowd pleaser type of movie (since they've wanted to release it during the Oscar seasons), and that is not going to happen. This is very much an art house film, what some typically call Weird.
