When it comes to making something major like Avengers 4, you have to know what you’re doing. There are a lot of characters and a lot of storylines they need to wrap up in two movies. Directors Anthony and Joe Russo knew the scale of the thing they were taking on, and they know that it’s their fault. Joe Russo admitted to Vanity Fair that they were the ones really pushing to bring everyone in.
We’ll take blame for the scale, because we were pushing for it. We were pushing to make it bigger, we were pushing it, saying, “Look, what you’ve done is an impressive narrative over 10 years, and why shouldn’t this involve every character?” It should be the culmination, so in some way, we have to touch on everyone in their story, or their theme. It has to be woven in, in some way. You can’t really look back and go, Hey, remember the last time that somebody took 12 franchises and blended them together and told the movie with 60 lead characters? So that’s the challenge, and you have to create your own structure for a story like that.
When asked if the Russo Brothers are involved with the future of the franchise after Avengers 4, Anthony revealed that they aren’t involved. They know who lives, who dies, and that this is only an ending for some of the characters — not all of them:
We’re not participating in any thought whatsoever about what happens after these movies. So we know who we’re allowed to kill, and that’s about it. I don’t even think Marvel had any ideas about where they would go after [Avengers 3 and 4]. It’s not an end for all of these characters; it’s an end for some of these characters. So some of these characters will go on. So it’s more complicated, that’s why it’s not a clean ending.
If everything was perfect at the end, there wouldn’t be a reason to keep going. Everyone is expecting there to be bodies on the ground. It’s just driving people insane trying to figure out who it’s going to be.
