The "script" for Area 51 reads much like I imagine the "script" for Paranormal Activity did. It's basically a scene-by-scene breakdown with a list of various props, actors, and the general interactions between the actors and their surroundings. There is no written dialogue, but within the action descriptions are general ideas that the actors will be using to improvise their lines with on set. Unlike Paranormal Activity's single location, Area 51 is far more expansive in its setting.
