Burstyn will play Portman’s character’s grandmother.
“Fargo” and “Legion” creator Noah Hawley is directing from a script by Brian C. Brown and Elliott DiGuiseppi. Reese Witherspoon, who was attached to star at one point, will produce with Bruna Papandrea.
The still-untitled film follows a female astronaut who, after coming back home from a mission in space, starts to unravel when confronted by her seemingly-perfect life. The film explores the theory that astronauts who spend long periods of time in space lose their sense of reality when they return home.
Hamm will play Portman’s fellow astronaut who she aggressively pursues after returning to Earth.
With “Legion” wrapped and Hawley’s other FX series, “Fargo,” not shooting until next year, production on the movie is expected to start in the spring.
Burstyn was last seen in the Sundance drama “The Tale,” which recently premiered on HBO. The veteran actress appeared in such pics as “The Exorcist” and more recently in “House of Cards.” She is repped by ICM Partners and MGMT.
