I just watched the trailer for Prometheus
[link] and then found a link to another short clip from the movie which is the coolest TED lecture I've seen yet -

There's more info here -

The credits show that the movies is "not yet rated" but if it's anything like the original Alien movie it should be rated "Fucking Terrifying".
I know a lot of people watch Alien now and say "it's not that scarey" but you have to remember that when it was originally made the only other really scarey movie was The Exorcist. There were no DVD players and even if you had a VCR you weren't going to be seeing a copy of it for many years so the only way to watch it was in the theatre... in the dark... with lots of other people who were easily scared.
Terror is contagious.
