Annette Bening Joining 'Captain Marvel' (Exclusive)

Mississippi Grind directors Anna Boden and Ryan Fleck are helming the movie, which is currently in production in and around Los Angeles. (The project also will shoot in Louisiana.)

Larson toplines the pic as Carol Danvers, an Air Force pilot whose DNA fuses with that of an alien, sending her headlong into an intergalactic adventure. The character had a major tease in Avengers: Infinity War, although the solo movie is set in the 1990s.

The cast already includes Jude Law, Ben Mendelsohn and Gemma Chan, as well as Djimon Hounsou and Lee Pace, with the latter pair reprising their characters from 2014’s Guardians of the Galaxy.  

Details on Bening’s character are being kept hidden deep in the Kree Empire, but "scientist" is said to be in her job description.

Bening eschews most studio movies, let alone those with caped crusaders and masked marvels. She most recently starred in the period drama Film Stars Don’t Die in Liverpool and toplines The Seagull, an adaptation of the Anton Chekhov play that also counts Saoirse Ronan and Elisabeth Moss in its cast, which is set to bow Friday.

Bening is repped by CAA.
