Let's take this with a rather large grain of salt again considering the source, but World of Reel is reporting today that Meryl and Sigourney Weaver are circling a project at Amazon entitled Useful Idiots. Thelma & Louise writer Callie Khouri wrote the screenplay and it apparently already has a director attached, Joseph Cedar. Cedar is known for his films Footmate and Norman, among others.
I did a little sleuthing and there are reports as far back as 2020 of Khouri having written The Useful Idiots (the "The" is in most of the articles I've seen other the the World of Reel one) as a series. The World of Reel article seemed to intimate that this would be a feature film, but who knows.
While Jordan Ruimy doesn't have the greatest of reputations among discerning readers whom I've followed, the fact that this is/was a legit project form Khouri and has a director already named/attached, along with a specific co-star, makes me feel that it wasn't conjured from thin air. Ruimy suggests that filming is set to start in January. If that were to happen, it doesn't seem like The Corrections would get underway before that time. Speaking of the latter project, I really want it to happen. It would be so dumb for it to essentially go through development hell three times only to never see the light of day as a screen production. But they may be taking a while to complete the script.
As far as The Useful Idiots, there is no mention in any source I can find of what it might be about. A "useful idiot" is, by definition "a pejorative description of a person, suggesting that the person thinks they are fighting for a cause without fully comprehending the consequences of their actions, and who does not realize they are being manipulated by the cause's leaders or by other political players." Seems likely to have a political bent to it, which is not surprising considering the times we live in and, of course, Meryl's interests.
After a year and a half of hand-wringing, if every rumored or announced project comes to fruition in the next couple of years, we could have:
The Devil Wears Prada 2
The Useful Idiots
Narnia (voice)
Joni Mitchell biopic
The Corrections
Mamma Mia! 3
Glad to see she's back!
