A Marvel Studios leak has possibly shed some new light on the Marvel Cinematic Universe's Phase 4. Part of the leak talks about Keanu Reeves being in negotiations to join The Eternals cast, which has already been previously reported. With that being said, it is not clear if this is the same source from where the Reeves news originated from, but the source has been reliable in the past. There are some potential Phase 4 spoilers below, so read ahead at your own risk.

James Gunn has already denied including Nova in Guardians of the Galaxy Vol. 3 after stating he did not want to introduce new characters in the final installment of the franchise. However, the new leak claims Marvel Studios might be making a standalone Nova movie, which MCU fans may be interested in. As far as Phase 4 movies and beyond are concerned, it looks like Black Widow, The Eternals, Black Panther 2, Shang-Chi, Doctor Strange 2, Nova, and Guardians of the Galaxy Vol 3 are what's being line-up next.

In addition to the aforementioned movies, there are reportedly plans to make Thor 4, Ant-Man 3, and Captain Marvel 2. As for further down the line, the source claims New Avengers, Young Avengers, and Dark Avengers movies are also in development at this time. This is a lot of information to take in and some of it may or may not end up happening when all is said and done. However, the person behind the leaks has been pretty on point over the past few years on Avengers: Endgame and Infinity War.

Black Panther 2 will reportedly see the return of Michael B. Jordan. This has been talked about quite a bit since the first installment hit theaters last year, though it has not been confirmed. After the events of Endgame, pretty much anything is possible from the time heists and its effects on the universe, so seeing Jordan come back isn't too much of a stretch. Apparently, Killmonger won't be resurrected, but will still "exist in Wakanda's 'spiritual plane.' The source also suggests the sequel will "be politically charged and teases the arrival of the Queen Divine Justice, a princess secretly raised in America by one of T'Challa's warriors."

Marvel Studios boss Kevin Feige is expected to give a substantial update on the MCU's Phase 4 at this summer's San Diego Comic-Con, but it is unclear just how far he'll go in talking about the future. Though the leaks mentioned above could be true, there are plenty of movies that never make it past the development stage, which means a Nova movie might not be happening. However, he could get introduced in Guardians of the Galaxy 3, which has been teased in the past to set up Phase 4, though that was all said before James Gunn was fired from the sequel. The Independent was the first to report on Roger Wardell's new Marvel Studios leaks.
