This thread right here is for an edit by strangeland. It began as the Weyland shareholder edition and may end up being called Leviticus.
The rest of us have been contributing ideas and feedback. If my suggestions prove too radical for strangeland then I will most likely begin an edit of my own - if that happens I will begin a new thread so as not to confuse things further.
The idea behind moving the action to LV 426 is mainly too to alter the film to be more like i was originally intended. The early scripts had the story take place there and at one point the film was going to be called LV 426.
Originally Ridley wanted to do something focused on 'the guy in the chair' - what eventually became the Engineer, since that was one aspect of the franchise that hadn't really been explored. Along the way the film transformed from actual prequel to vague tie-in.
