I'd been wondering if filming was underway for The Post (no longer the title, but haven't seen official release on new title) as I had previously seen that May 22 was supposed to be the date. It now appears that they may still technically be in pre-production, as Meryl, Tom Hanks and Steven Spielberg were on hand this morning at the Washington Post to observe a meeting, likely for research purposes.
All previous indications have been that filming was set to start in May, knowing that it is supposed to be released in December. Maybe it will officially begin next week (still May). Regardless, just glad to see some action on this!
