I want this project to come to fruition. I really don't care about the Prometheus movies. I've never thought of the Alien series as "Ridley Scotts' franchise" and it truly isn't. He does not own the rights to the characters/stories, those belong to 20th Century Fox. He only directed 1 film until 2012, not like he was involved in every movie.
For Pete's sake, just do the film before the actors and actresses die! Then ANY chance of this movie being made will be dead, for sake of consistency. If it sucks, so be it. Didn't the majority want a second AvP film? We didn't know how awful it would be til afterwards. However, if Cameron, Weaver AND Scott all seemed to like the movie script, isn't that saying something from the people that brought these characters to life?
