Hawley is set to direct the Fox Searchlight drama about a married astronaut who begins an affair upon returning to Earth.

Dan Stevens will reteam with his Legion creator-showrunner Noah Hawley for his untitled Fox Searchlight drama.

The Beauty and the Beast star will join Natalie Portman, Jon Hamm and Zazie Beetz in the astronaut story that Hawley is set to direct.

The project, formerly known as Pale Blue Dot centers on a married astronaut (Portman) who returns to Earth after a mission and begins an affair with a fellow astronaut. She heads into a downward spiral as she loses her connection to her family — a condition that can afflict those who spend a long time in space — and when her lover begins another affair with an astronaut trainee, the bottom drops out.

Hamm is playing the fellow astronaut, while Beetz is the other point in the love triangle, the trainee.

Stevens will portray Portman's husband.

Brian C. Brown and Elliott DiGuiseppi wrote the script for the feature, which was inspired by a true-life astronaut love triangle in which a female mission specialist tried to kidnap a rival in 2007.

Stevens, who is repped by WME, the U.K.'s Julian Belfrage and Peikoff Mahan, is in the midst of his second season on Legion, Hawley's X-Men-based series on FX. He has Gareth Evans' Netflix drama Apostle in the can for a possible release later this year and this week joined Elisabeth Moss, Amber Heard and Cara Delevigne in the punk rock drama Her Smell.

Updated May 17, 2018 to reflect that the project is untitled at the time of this news.
