Justin Theroux is set to write a draft of Space Invader, an astronaut romantic comedy at Fox, says The Hollywood Reporter.
Mike Lisbe and Nate Reger originally wrote the film, which centers on a man who decides to go to space after he suspects that his longtime girlfriend, an astronaut, is cheating on him with another spacewalker.
Will Arnett is attached to star.
Theroux could potentially direct the title as well.
