Justin Theroux's second-act career as a screenwriter has been incredibly entertaining to watch, both because you never expect that actors are paying enough attention on set to go behind the scenes, and hey, every time Variety runs a picture of him, it's never a bad thing. Theroux, once an actor known for roles on Six Feet Under and Charlie's Angels, parlayed his writing work on Tropic Thunder into a gig on Iron Man 2, and now the screenplay jobs just keep rolling in.

According to THR, Fox has hired Theroux to write another draft of Space Invader, which is blessedly not an adaptation of the classic arcade game. Instead it's being described as an "astronaut romantic comedy," with Will Arnett attached to play a man who travels to space when he suspects his astronaut girlfriend is cheating on him with another NASA guy.

I really like everything I'm reading about this, especially the fact that it's a leading role for Will Arnett, who has been brilliant on television (his scenes with Alec Baldwin on 30 Rock are about as good as comedy can get) but underused in the movies. Psychotic jealous civilian in space sounds perfect-- particularly if he brings his chicken impression with him.
