20 Things You Somehow Missed In Alien

Alien, both in its development stage and in reviews from critics, drew numerous comparisons to the movie Jaws. Understandable really, as both concern a rag-tag group of survivors attempting to best a terrifying creature as it slowly whittles them down one by one. One write-up just called it "Jaws in space".

However there's another, very deliberate, reference to Spielberg's notorious shark movie, as Ash (or rather, Ash's head) describes the Xenomorph as a "perfect killing machine". This was included by Ridley Scott as a nod to Jaws, where Matt Hooper calls the shark "a perfect engine, an eating machine".
