Alien; a quasi perfect mix of horror and science fiction.
If you like
sf and horror, I can recommend "Quatermass and the pit", the full movie. I think it was a great mix of those two genres as well.
Also the
FPS game "System shock 2" despite horribly dated graphic should satisfy your hunger for a god horror
sf game.
Everyone should see "The rocky horror picture show" at least once, in a real honest to ghawd theater, with full audience participation. It is an experience you will never forget.
