In an interview with Empire recently, Scott said: “The question is, do you go for the PG-13, [which] financially makes quite a difference, or do you go for what it should be, which is R? Essentially, it’s kinda R. It’s not just about the blood, it’s about ideas that are very stressful. I’m not an idiot, but I’ll do everything I can to get the most aggressive film I can.”
Continuing his conversation with the outlet, Scott revealed why he was interested in revisiting the universe of Alien:
“I always wondered when they did [Aliens] 2,3 and 4 why they hadn’t touched upon that, instead of evolving into some other fantastic story. They missed the biggest question of them all: who’s the big guy? And where were they going? And with what? Why that cargo? There’s all kinds of questions.”
By the “big guy” he’s referring, of course, to the Space Jockey, seen in Alien and in the promotional materials for Prometheus. With quotes like that, it looks like Scott is finally coming out of his shell and openly admitting there are much larger connections between Alien and Prometheus than he was willing to admit before.
