For those who don't know Prometheus is Ridley Scott's prequel to Alien which of course he also directed) & was one of the films that fired my imagination when I was growing up.

I know you shouldn't purely go on the trailer for any film but if the trailer is anything to go by it looks scary!

I've heard that Scott is doing a P-13 & a R rated version

I can't see how a film like this could work as a PG-13
