Première Magazine's Editor-in-chief, Mathieu Carratier tweeted this morning about Rob and two directors. He said that Rob is set up to work with Werner Herzog and is "spending time" with Harmony Korine.
Ok, real info then: Robert Pattinson is preparing a movie with Werner Herzog.
Since it seems to interest you, I can also tell you that Robert Pattinson has been spending time with Harmony Korine lately.
While we don't have any confirmed details about that information, what we DO KNOW is that Première is a very respectable magazine and the tweets came directly from its Editor-in-chief. His later tweets show that he doesn't have a lot more info about this movie but hopefully we'll know more soon enough.
