2 versions of Prometheus

If the latest pics of the SJs (as statues) proves not to be fake, then I'll be somewhat disappointed! I'm starting to think Lucas - Phantam Menace (we all know he should have left well alone). As it's only early days and I still have faith in the Ridler, I'm trying to make excuses for that pic. In an interview that Ridley did: http://www.youtube.com/watch?v=5LeIce4lc8s he mentions that there's two versions of Prometheus being shot - for different age ratings (13 & 18). Perhaps the skeletal monstrocities are explained away as suits in the 13 rating - whereas in the 18 rating they are the aliens we have come to expect? Just a thought....
