Justin Theroux Heads Into “Space”

Justin Theroux is set to pen the script for the astronaut romantic comedy “Space Invader” for 20th Century Fox and Davis Entertainment says The Hollywood Reporter.

The story 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. Mike Lisbe and Nate Reger penned the original draft.

Theroux, who penned “Tropic Thunder” and the upcoming “Iron Man” Sequel, could potentially direct as well.
