Avengers 3 and 4 are standalone movies and there will be at least 3 Star Wars Han Solo movies

Marvel Avengers 3 and Avengers 4 will not be a two-parter. The studio will release the first part “Avengers: Infinity War” as a standalone movie on May 4, 2018. The second film, now called “Avengers Untitled,” will hit as planned on May 3, 2019.

“The movies are two very different movies,” answered Joe Russo. Directors Joe and Anthony Russo directed Captain America Winters Soldier and Captain America Civil War.

They said it is misleading having them labeled as “Part 1” and “Part 2”

Star Wars Han Solo

26 year-old ‘Hail Caesar!’ scene-stealer Alden Ehrenreich will be the new Han Solo. The new plan is to make at least three Star Wars Han Solo movies.
