Alien casts a very long shadow. Ever since Ridley Scott’s movie came out (a frankly horrifying number of years ago), its long, spiky fingerprints have been all over science fiction horror cinema. People in jumpsuits, interpersonal conflict, a betrayal or three, a near total party kill, an action sequence in a near vacuum, aaaaaaaand scene! Relatively easy to replicate, not so easy to build upon, although several notables have tried. Personally, I like the hard left turn that Event Horizon takes into full-on horror, for example, but it’s an acquired taste.
So, if anything you do as a filmmaker is going to be compared to Alien or its ilk, you’re faced with two choices. Either do something as original as possible, or make the best possible version of the movie that people are expecting to see.
Life does the latter. And still throws in a couple of surprises along the way.
