Phase Three of the Marvel Cinematic Universe is well underway with every film in it, save for one, already having been released, filmed, or at least gone into production. The only Phase Three film yet to go before cameras is Captain Marvel, which will do so early next year to be ready for its March 2019 release. Despite being the last film of its respective Phase to go into production, Captain Marvel will play a critical role in setting up Untitled Avengers, the 22-movie conclusion that hits theaters just two months later in May 2019.

During a recent interview with IndieWire, Marvel Studios President Kevin Feige was asked how the future of the MCU could be shaped by the clear demand for more female-led superhero franchises, in front of and behind the camera, as evidenced by the success of Wonder Woman earlier this year. Feige said that there are a lot of discussions, but that Marvel isn’t ready to go public with any post-Phase Three plans just yet (beyond the already announced Spider-Man: Homecoming sequel and Guardians of the Galaxy Vol. 3).

For now, Feige and his team are all about the handful of films that are still right in front of them, including Captain Marvel. The Marvel boss was a little more forthcoming about that film’s role in the bigger picture of the MCU as it relates to the rest of Phase Three.

“We’re really focusing on Captain Marvel and the work that [directors] Anna [Boden] and Ryan [Fleck] are doing. It’s going to be a big part of heading towards this epic conclusion and epic finale of 22 movies over the course of 10 years. That is focus for the next six movies we have to finish and get out.

“The focus now is on delivering Captain Marvel and then bringing Captain Marvel’s story into the finale of everything we’ve started thus far.”

We all know that Captain Marvel herself, Carol Danvers (Brie Larson), is a sure bet to appear in Untitled Avengers, so her presence alone might be all that Feige is referring to. Feige has previously described Captain Marvel as the most powerful hero in the MCU, so she is probably going to play a big role in The Avengers ultimately (the universe hopes) defeating Thanos (Josh Brolin) once and for all, as the heroes probably won’t be able to finish the job in Avengers: Infinity War in May 2018.

The contribution of Captain Marvel to Untitled Avengers could also go beyond the former film’s title character. As announced at San Diego Comic Con back in July, Captain Marvel, set in the 1990s, will feature the debut of The Skrulls in the MCU. The shapeshifting alien antagonists that will challenge Carol Danvers in her first solo film could return to cause some last minute problems for The Avengers.

Infinity Gauntlet is the most immediately identifiable comic book inspiration for Avengers: Infinity War and Untitled Avengers thanks to Thanos and the Infinity Stones plot that’s been developing over all three Phases of the MCU. There is, however, another, much more recent source of inspiration in Jonathan Hickman’s 2013 Marvel Comics event series, Infinity. We know that Infinity is a factor because the Children of Thanos, known in the comics as the Black Order, were introduced in that series and have been confirmed for Avengers: Infinity War.

The Skrulls were not part of Infinity, but there was another race of aliens, the Builders, with whom The Avengers went to war while also having to worry about Thanos. Perhaps the MCU will swap out the Builders in exchange for the much more iconic Skrulls to give The Avengers as big of a combined threat as Marvel fans can possibly imagine.

All of that is pure speculation, however, so let’s not get too far ahead of ourselves. We all expect the Skrulls to be a big factor in the MCU, with Secret Invasion being a major, Skrull-starring event that fans have earmarked for Phase Four. We may just see the Skrulls being a bigger factor earlier than we think, or perhaps Feige’s comments really are all about Carol Danvers knocking out the Mad Titan with a mean uppercut.

Captain Marvel is in theaters March 8, 2019.
