Next question is the infamous "cocoon" scene. I've seen fan edits that've put the scene in before AND after Ripley turns on the self destruct switches. Not sure who said this, but I agree with their analysis: "The scene has no clear starting point. Place the scene before hitting the switch and you lose the suspense of her running from the Alien and getting the final act in motion (scene drags on too long). Place it during the self destruct countdown, and you lose continuity with the countdown (again, scene drags on too long)."
Not an exact quote but you get what they mean. I think they also said that Ridley Scott never really established where this scene would fit into the narrative when he shot it. Probably the reason it got the axe. So the big question now is, where will the scene go in your edit?
