No, the MCU is still not doing Civil War.
Robert Downey Jr being “in talks” to be in Cap 3 is absolutely meaningless. Remember last week when he was “in talks” to do Iron Man 4? Renner was “in talks” to be in Cap 2 and to be in Cap 3. Both Joaquin Phoenix and Benedict Cumberbatch have been “in talks” to play Doctor Strange.
Scarlett Johansson is in talks to star in a Black Widow solo film.
"In talks" is just a buzzword used by the entertainment industry to mean that at some point two people talked about maybe doing the thing. In no way does it mean they’ll ever do the thing, or even that anyone will ever do the thing.
The variety article that started all of this is a bunch of bullshit, written by a slavering Civil War fanboy who doesn’t understand nuance. Someone, somewhere said that RDJ is in talks for Cap 3, and the “journalist” jumped to the conclusion that a) this meant he’s in talks to co-lead, and b) that the only reason that Steve and Tony might ever interact in a film is Civil War. If you read the rest of the article, he even takes a quote from the Russos about how we’ll be super excited to see who they’re getting for Cap 3 as “proof” that the Russos mean it’s RDJ, and proof that that means Civil War.
Even though the Russos have already told us that Cap 3 is going to be focused on the Steve/Bucky relationship and the Winter Soldier.
Even though “in talks to be in Cap 3” doesn’t remotely mean “in talks to be the co-lead in Cap 3”.
From an in-universe perspective, even though everyone knows Steve Rogers is Captain America (he has a Smithsonian exhibit, for crying out loud!). Even though Natasha already leaked everyone’s sensitive data onto the internet. And even though there are less than a dozen superheroes in the MCU at this point
It’s an article full of biased suppositions, based on an un-finalized rumor, designed for page views and to generate site traffic immediately after NYCC. It doesn’t mean anything. I expected more of Variety, tbh.
Age of Ultron will not be planting any seeds for Civil War. If you’ve seen the footage that Marvel showed at SDCC and NYCC, you know that there’s no room in this story for that. And there’s no way they’d leap into and tell the whole story of Civil War in a solo film without prior groundwork being laid. If they do Civil War, it won’t be until Phase 4, at minimum, since Phase 3 is almost definitely going to pay off the Thanos teaser from the end of Avengers.
Also, Agent M tweeting a picture of the cover of a first issue of Civil War (which I’ve heard will be a reissue, rather than a reboot), doesn’t mean they’ve confirmed they’re rebooting anything. It means they’ve shown us the cover of something that will come out next summer. Literally just that.
If you were at NYCC, you know that they’re 100% focused on Secret Wars, what they’ve called the “biggest event Marvel Comics has ever done”, which will happen in May of 2015. I can’t count the number of times I heard “in 8 months, time runs out” and that this will impact literally every single title the company produces (potentially into the MCU or cartoons, but nothing confirmed there). Why would they do something that epic and then decide to do Civil War again? It doesn’t make sense.
So please relax, guys, it isn’t happening.
