During a set visit by Screen Rant and other outlets, director Joe Russo revealed the original direction for the film has changed drastically.
"It isn't a true two-parter," he said. "I think the two-parter concept came back when Marvel decided they were going to culminate the MCU, it was going to be a two-movie deal. But as we developed the movie, in execution, it ended up being more of two singular expressions."
Of course, the two films will still have the same connective tissue fans of the Marvel Cinematic Universe have come to expect. Russo explained the links are more akin to those between Captain America: The Winter Soldier and Captain America: Civil War.
"[The films relate to each other] in the way that The Winter Soldier relates to Civil War, and the way that Civil War relates to Infinity War," he said. "These two movies will also relate. There's a narrative thread that is connecting these films, but at the same time, there's an independence in terms of what the experience is or where the story goes."
