According to Collider and UPROXX who recently sat down with the directors of Captain America: Civil war, there seem to be a few changes coming to the MCU. Directors Anthony and Joe Russo have said that even though Avengers: Infinity War - Part 1 and Avengers: Infinity War - Part 2 has a common villain Thanos, the movie titles will change. The brothers while speaking with UPROXX recently said that "the movies are two very different movies" they also were asked if the "Part 1" and "Part 2" subheadings were misleading, to which Anthony replied: "It is misleading" before Joe clarified and revealed that the films would be retitled: "The intention is we will change it, we just haven’t come up with the titles yet. But, yes, we will change it. And, yes, that is a scoop: we will retitle them.”
While speaking to Collider the Brothers were questioned on if Scarlett Johansson's Black Widow would get a solo movie to which they replied saying:
ANTHONY RUSSO: "It’s a no-brainer, right?"
JOE RUSSO: "I don’t think [it’ll take] much. I think it’s just a function of where on the slate it goes. She’s a bad-ass."
