SPOILER WARNING: The following article contains potential spoilers for Marvel Studios' Captain Marvel film.
A script from the upcoming Captain Marvel film has reportedly leaked, bringing with it a number of potential spoilers from the anticipated film. As always with this sort of report, take the information below with a big grain of salt; even if the script does prove to be genuine, Marvel Studios is still months away from even starting principle photography, so there are more than likely numerous story changes still being debated.
According to MCU Exchange, the movie will be maintaining some aspect of Carol Danvers' link to Mar-Vell, aka the original Captain Marvel, intact. It's unclear as to how direct of a role Mar-Vell will play in Carol's origin story, or if he'll even appear in his classic costume, but considering .
Another aspect of the comics that is reportedly in the script is the Psyche-Magnitron machine. The device, built by the Kree, has a number of uses, but perhaps its most important is the ability to bestow people with super powers. It shares a long, somewhat tangled history with Carol Danvers, and is responsible for her becoming a superhero in the first place; in the comics, the machine responded to her half-Kree DNA, tapped into a subconscious desire to become a superhero, and stole energy from Mar-Vell's Nega Bands (special gauntlets that amplified and added to Mar-Vell's inherent abilities) in order to transform her into a superhuman. In the purported script for Captain Marvel, the Psyche-Magnitron is once again presented as the means by which Carol finds herself imbued with superhuman abilities.
In addition to giving Carol her powers, the Psyche-Magnitron will have an additional effect on her half-Kree, half-human genetic makeup, essentially slowing her aging to a crawl. This, rather than a story device like suspended animation, will theoretically explain how Captain Marvel could have been operating in the Marvel Cinematic Universe in the 1990s and appear in the wake of Avengers: Infinity War without appearing to have aged.
Finally, longtime fans of the character will be pleased to learn that plans are for Carol's original costumed identity, Ms. Marvel, to be addressed in some capacity. Whether this means we'll see Carol suit up and fight crime in her pre-Captain Marvel days remains unclear, but her original costume will make an on-screen appearance in some capacity.
Again, this is all based on what is reportedly a legitimate script, but even if the script is the real deal, there is on guarantee that all -- or any, for that matter -- of it will survive until the film actually heads into shooting, much less wraps. The stories for even the biggest movies are notoriously fluid, often changing on the fly in response to how a director or studio sees the way things are coming together. For a production as massive as Captain Marvel, which is not only Marvel Studios' highly-anticipated, first female-led feature, but will launch with strong ties to the ongoing multi-movie storylines that have been built for years, well -- let's just say it's a safe bet that some things are going to change before the final cut arrives in theaters in 2019.
Starring Brie Larson as Carol Danvers, Captain Marvel is set in the 1990s, and will draw upon elements of Marvel Comics’ Kree/Skrull War.
Directed by Anna Boden and Ryan Fleck from a script by Nicole Perlman and Meg LeFauve, the film also stars Samuel L. Jackson as Nick Fury. Captain Marvel arrives March 8, 2019.
