Annette Bening has boarded upcoming Marvel standalone movie, Captain Marvel. Speculation is rife about which classic comic book character she might play.

Who Will She Play?

The four-time Oscar nominee will star opposite Brie Larson in the superhero movie. She will most likely play her character's mother, Marie Danvers, who has a small role in the comics, but discovers her daughter's secret identity after she dramatically saves her father's life.

Although the two women initially enjoyed a good relationship, it all falls apart following Captain Marvel's run-in with Rogue, who strips her of all memories and emotions. As a result, the Danvers women eventually end up having an epic mother-daughter fight.

Another possibility is that she could feature as a scientist, working alongside Gemma Chan's Minn-Erva, also a scientist, which would tie Marie into her daughter's supernatural world a bit more.

Bening could also play pilot Helen Cobb, a pilot Carol Danvers was inspired by in the comics. Danvers fought alongside the pilot, and if this is the case, she will take the role of mentor.

Likewise, the actress could play journalist Tracy Burke, who works for Danvers during her tenure as a magazine editor. The two have a sweetly close relationship, but Burke dies later on in the comics, so it's unlikely she'll pop up in Captain Marvel.

An Exciting Proposition

Jude Law, Ben Mendelsohn, and Chan are already confirmed to appear along with Bening. Half Nelson duo Anna Boden and Ryan Fleck directed the flick. Marvel head honcho Kevin Feige is producing.

Geneva Robertson-Dworet penned the most recent iteration of the script, with Inside Out's Meg LeFauve and Nicole Perlman submitting previous drafts.

Captain Marvel, which is currently in production ahead of a March 2019 release date, follows the story of Larson's Carol Danvers. An Air Force pilot, whose DNA fused with that of an alien thanks to an accident, Danvers becomes the titular hero after being imbued with the superpowers of strength, energy projection, and flight.

Feige confirmed at last year's San Diego Comic-Con that the movie would be set in the nineties, with Larson spotted on set sporting a classic "Rachel" hairstyle, from iconic show Friends. The story takes place before the Avengers, with Samuel L. Jackson reprising his role as Nick Fury.

This marks Bening's first foray into superhero movies. Her next appearance will be in the drama The Seagull.
