Here's some stuff about the IW movies that came out these days from Russos/Feige/writers
>Directors Anthony and Joe Russo confirmed that they’ll shoot both movies, which are currently scheduled for release in May 2018 and May 2019 respectively, at the same time. But they stressed that the back-to-back filming doesn’t mean it’s just one story split in half.
>“The movies are very very different from one another,” said Anthony Russo. “It’s not a part one and part two scenario, necessarily. They’re just two different expressions. I think it creates a misconception that we’re shooting them at the same time.”
>When we asked writers Christopher Markus and Stephen McFeely about that statement, they confirmed the sentiment, but refused to elaborate. “I will agree [the two movies are very different], and that was very important to all of us,” McFeely said.
>For some clue as to what the different movies could entail (outside of probably Thanos, the Infinity Gems, and all the Avengers), the Russos pointed to the past. That Infinity War will continue a story they’ve been working on for some time. “For us there’s a through line from Winter Soldier, through Civil War, right to Infinity War,” said Anthony Russo. “In our mind, the storytelling arc moves that way.”
>“There’s an overarching story that’s going to be told through all four films,” added Joe Russo. “And I think having the amount of characters we have in [Civil War] certainly prepares us to deal with probably triple the amount of characters in Infinity War.”
>“Much of the groundwork has already been laid,” he said. “That’s the truth. Doctor Strange will lay some more. Thor: Ragnarok will lay some more—but I think the majority of it is already there.”
