The making of Avengers 4 is shrouded in mystery - it’s going to be one of the biggest, most-anticipated films ever made, and keeping plot details under-wraps is of utmost importance. In fact, things are so secret, that not even the cast know what happens.
Mark Ruffalo revealed all (or as much as he was allowed to/knew himself) when he appeared on The Marvelist podcast, saying:
“We’re doing reshoots starting in September, and then we’ll go back into the international tour, we’ll go on tour. Then you guys will get the second installment. Which we don’t even know what it’s gonna be yet.
“We’re not just doing reshoots; we’re going to finish the movie, which we really didn’t get to finish totally when we left it last year.”
According to reports, the movie is having the reshoots in response to the popularity of certain characters like Black Panther, meaning that Wakanda is to be featured more heavily. Ruffalo said of the Russo brothers’ approach to directing:
“I don’t even know that they really know exactly. Some of it is happening while we’re there. It’s pretty amazing. And we’ll shoot some stuff and a few days later come back and reshoot it cause we wanna take it in another direction. It’s a very living organism, even as we approach it being a locked picture, we’re still working on it.”
They even stretched to writing fake endings so that cast-members with large mouths like Tom Holland don’t let the secrets slip and ruin it for everyone. And the recent Guardians of the Galaxy furore will have of course affected elements of Avengers 4, so a couple of last minute tweaks here and there shouldn’t spell disaster or hint at too many other problems, as reshoots normally do.
Either way, they could reshoot the entire thing and everyone will still see it. Nothing can make this movie fail. Even if it turned out every member of the cast were “bad” - this film will bang.
