Sci-fi rom-com Space Invader (nothing to do with the arcade game, you'll be pleased to hear) has been in Development Hell for a while now. In early 2007 it was being talked up as a vehicle for Arrested Development's Will Arnett, with a script by Futurama alumnus Mike Lisbe. Three years later, Justin Theroux, the actor-turned-screenwriter who wrote Tropic Thunder and Iron Man 2, has come aboard to pen a new draft.

Theroux may also direct the film, which is reportedly about a guy who becomes a space station janitor to keep tabs on his girlfriend, who he suspects is knocking off a Zapp Brannigan-style space blowhard. Will Arnett is still starring, according to THR, but whether Lisbe and his co-writer Nate Reger are still involved, having orginally sold the project to Fox, is unclear.

That everyman-in-space scenario is kind of familiar, particularly in Britain, from things like The Hitch-Hiker's Guide to the Galaxy and Red Dwarf, but we don't think we've quite seen it played as a Hollywood romantic comedy before. Maybe you can jog our memories below.
