I don’t know… I keep reading Ridley Scott’s response to Baz Bamigboye at The Daily Mail differntly than many others. From the article… “I asked if Noomi Rapace…would be working with him in Australia and he said no. ‘We’re still casting the main roles,’ he said.” That doesn’t say Noomi Rapace is not in the film at all, it just confirms she won’t be working with them in Australia (she could have already shot her scenes, especially if short). Couple that with her response at the Cirque du Soleil Amaluna event just the other day (it’s on YouTube). She smirks, then smiles and laughs while saying “no comment on that yet”. That seems to me to be the response from someone in the film, but can’t say anything as it could be a major part of the story, even if she is not in the film much. Kind of like Luke Skywalker was. Back in November of 2015, Scott did say how much of a juggernaut the new Star Wars movie would be and his reasoning for making sequels to ‘Prometheus’. Maybe he took more inspiration from the new Star Wars than just the idea of sequels?
