Although Brie Larson's on-screen debut as Captain Marvel is scheduled to be released two months before the fourth Avengers film arrives, the Academy Award-winning actor filmed her scenes for the ensemble movie ahead of her solo debut.
In a spoiler-filled interview with Collider, Avengers: Infinity War co-writers Christopher Markus and Stephen McFeely revealed that Larson actually filmed scenes as the latest MCU hero for Avengers 4 months before filming on the Captain Marvel solo film even began.
"We were in the position we were in with Spider-Man [Homecoming] and [Black] Panther where Brie was going to have to shoot her scenes, I think its ok to say, before she shot Captain Marvel so we can’t really talk about what we decided, but it was clearly a conversation we had to have with [Captain Marvel directors] Ryan [Fleck] and Anna [Boden]" McFeely explained. "So you are bringing directors on and we're trying to set up something that will work for our movie and not screw up their movie."
Since Avengers 4 finished principal photography this past January, while Captain Marvel began filming in March, having Larson first taking on the role in front of cameras for the untitled Avengers sequel makes logistical sense. It also confirms an earlier claim by actor Josh Brolin last month who revealed he had already filmed scenes with Larson for Avengers 4.
With Avengers 4 directors Joe and Anthony Russo recently admitting that they haven't completely finished filming the Infinity War follow-up, Larson may very well end up filming her role in the sequel both before and after Captain Marvel has completely wrapped.
Directed by Anna Boden and Ryan Fleck from a script they wrote with Liz Flahive, Carly Mensch, Meg LeFauve, Nicole Perlman, and Geneva Robertson-Dworet, Captain Marvel stars Brie Larson as Carol Danvers, Samuel L. Jackson as Nick Fury, Jude Law as Mar-Vell, Clark Gregg as Phil Coulson, Lee Pace as Ronan the Accuser, Djimon Hounsou as Korath the Pursuer, Gemma Chan as Minn-Erva, and Ben Mendelsohn, Lashana Lynch, Algenis Perez Soto, McKenna Grace, and Annette Bening in as-yet-undisclosed roles. The film arrives on March 8, 2019.
