Prometheus

I like science fiction movies by Ridley Scott. With aliens. And replicants.

Isnt that the (unoffical) prequel to Alien? Supposed to explain how the alien ship got there, and what the deal was with the "Space Cowboy?"

Also, was "Alien" as good a horror movie as "Aliens" was an action flick? Was either as good as Alien3 was bad? Discuss.

If you haven't seen Alien or Aliens, you're missing out.

Those are the only two movies in the franchise. I've heard rumours of others, but it's simply not true. There's also only one Matrix movie, a shame they didn't make more.

It's not unofficial, it's a prequal to Alien. It will focus on the Space Jockey and the ship heavily.
