It seems as if Ridley Scott is showing off snippets of Prometheus to some members of the press, as the Telegraph in the UK has seen some footage and revealed new details. They confirm who the company person is, who the android is, who the Ripley equal is, and that the planet isn’t LV-426.
The big news is that there is a direct connection to the first Alien movie, but it’s only at the very end of Prometheus:
For Scott the starting-point – how the big bone creature from Alien came to be there – became less and less important as the new movie took over, or, as he says, “adjusted itself into much larger questions”. The origin story ended up “barely in its DNA” – the last seven minutes provide the link.
So while we’ve all known it’s an Alien prequel, there’s final confirmation that there really is a direct link to the first movie in Prometheus.
