We've known since last month that Brie Larson will be joined in Captain Marvel by not only Samuel L. Jackson as Nick Fury but three other returning Marvel Cinematic Universe actors -- Clark Gregg as Agent Phil Coulson, Lee Pace as Ronan the Accuser and Djimon Hounsou as Korath the Pursuer -- and now we have some insight into why.
During a press event for Avengers: Infinity War, Marvel Studios President Kevin Feige explained to io9 why those four characters are important to Carol Danvers' story.
"It was the backstory of those characters crossing over into Kree mythology, and Kree lore, that just made it made it work," Feige explained, referring to one of Marvel's alien races. "And I always think it’s fun to see, most obviously with Fury in Captain Marvel, but also to a certain extent you’ll see with Ronan and Korath, characters the way they were before they became the icons that you have seen in other films. And it’s just fun to see people in different environments."
Last seen as the principal antagonist in 2014's Guardians of the Galaxy, Ronan is a Kree fanatic who attempted to use one of the Infinity Stones to destroy the Nova Corps' home world of Xandar, and employed Korath to help him in exact his revenge. Ronan died in that film, but Captain Marvel's 1990s setting enables the character to be brought back.
It also permits the return of Phil Coulson, widely believed by the heroes of the MCU to have been killed by Loki in 2012's The Avengers, only to be secretly revived on Agents of S.H.I.E.L.D.
Directed by Anna Boden and Ryan Fleck, Captain Marvel stars Brie Larson as Carol Danvers/Captain Marvel, Samuel L. Jackson as Nick Fury, Jude Law as Walter Lawson/Mar-Vell, Gemma Chan as Minn-Erva, Clark Gregg as Phil Coulson, Lee Pace as Ronan the Accuser, Djimon Honsou as Korath, and Ben Mendelsohn and Lashana Lynch in undisclosed roles. The film is currently in principal photography and scheduled for release on March 8, 2019.
