Anthony Mackie, who plays Sam Wilson aka The Falcon in the Marvel Cinematic Universe (MCU), recently assumed the title of Captain America.
The fourth 'Captain America' is likely to continue to Wilson's story though there is no official update on the casting.
Diversity will continue to be significant for Marvel Studios, which is behind one of the most successful films - "Black Panther", a film that had a nearly all-black cast.
Coogler found that Black Panther's appearance in 'Captain America: Civil War' was 'a great jumping off point'.
Things just got serious and dark in the Marvel Universe as the supervillain 'Thanos' enters the scene in the new Avengers: Infinity Wars trailer.
