The Russo Brothers are clearly very excited about the upcoming third Avengers film in the MCU. They are “Accidentally” leaking lots of small details about the film all over the place. Most recently the duo may have let it slip that the comic books character, Captain Marvel will make an appearance in the third installment of the Avengers series.
The Russos already confirmed the appearance of 68 Marvel universe characters in the films so it would not be a stretch that Captain Marvel is one of those 68. After speaking at a Marvel event hosted by the Smithsonian Institute this past Friday, the Russo brothers appeared to let it slip that Captain Marvel will make her big screen debut at some point during part 1 or part 2.
It was also revealed last week that the next Avengers film is no longer being titled Infinity War: Part 1 and Part 2.
Currently, there are still plans from Marvel to make a Captain Marvel film though the slot has been pushed back several times. The production of Captain Marvel was first announced back in 2014, but then had its release date pushed back to March 2019 from July 2018 As of now, no announcement has been made as to who will play the Air Force pilot Carol Danvers.
