The actor who gave life to Watson in the Sherlock series, starring Benedict Cumberbatch, will play Everett Ross again at MCU.
There is not much data on Black Panther 2 yet, but actor Martin Freeman has claimed that his character will return in this movie.
One of the actors who participated in Black Panther, Martin Freeman, known above all for his role as Dr. John Watson in the Sherlock series and his portrayal of Bilbo Baggins in The Hobbit films, commented in an interview with Collider that he will play again Everett Ross in the Marvel Cinematic Universe and who will be in Black Panther 2:
As far as I know, I will return.
As far as I know, I'll be in another Black Panther movie. That is what I understand. As for when that will happen, I don't know.
There is hardly any data on Black Panther 2, but most likely it will be in Phase 5 of Marvel alongside Captain Marvel 2, Guardians of the Galaxy Vol. 3 and Blade. We will have to be patient until the arrival of these films, but with the number of films and series announced for Phase 4, among which we find Doctor Strange in the multiverse of madness, WandaVision, Loki, Thor: Love and Thunder and Hawkeye, among others, we will have plenty of entertainment while we wait for the return of the king of Wakanda
