Ben Stiller had long been rumored as a potential participant in Ghostbusters 3, but now he’s got a spirit-harvesting comedy of his very own. Variety reports that Stiller will star in Rentaghost, based on the 1976 British children’s series about a dead man who sets up a temp agency for ghosts. The potential franchise starter, which was formerly in development as a Russell Brand vehicle, will be scripted by Stiller’s Night at the Museum writers Thomas Lennon and Robert Ben Garant.
