Jon Hamm, best known for his leading role in Mad Men, appears to have been added to the cast of Pale Blue Dot. He’s set to star alongside the infallible Natalie Portman. She’s to play an astronaut who upon returning from a long mission finds that it’s difficult re-acclimating to her old existence. While the pillars of her life crumble she decides to begin an affair with a fellow astronaut (Hamm). This man later initiates another affair on top of theirs with a female Air-Force captain; laying the groundwork for Portman’s character to execute some fairly misguided plans

As strange as that premise might sound, the film is in fact based on actual events. If the movie remains true to the story, Hamm will be playing Cmdr. Bill Oefelein while Portman will portray Capt. Lisa Marie Nowak. As of now the third member of this love triangle, Air Force Capt. Colleen Shipman, has yet to be cast. The original events took place around 2007 and ended in a bizarre case of kidnapping and attempted murder.

Noah Hawley, the creative juggernaut behind Legion and Fargo, will be directing the film. While Hawley has reportedly made adjustments to the script, it’s mainly penned by Brian C. Brown (a producer on Legion) and John-Henry Butterworth (Edge of Tomorrow).
