Variety is reporting that The Post will be given a limited release on December 22 of this year and then be expanded nationwide three weeks later, on January 12. As we were expecting, this will make the film eligible for the 2018 Oscars. No official word on the exact date filming is set to start, but considering this news, I expect it will remain on schedule and begin sometime in May, as previously reported.
Strangely, the article cited states that the film is currently untitled, calling it "Steven Spielberg's untitled Pentagon Papers drama." I imagine that's just bad reporting, and that they're not changing the name of the movie.
Looking forward to info on casting soon!
