Fede Álvarez muistetaan sellaisista elokuvista kuin Don't Breathe ja Evil Dead (2013). Hänen uusin leffansa Alien: Romulus on nyt katsottavissa. Tarinallisesti liikutaan Alienin ja Aliensin välissä. Tehosteet on pyritty tekemään mahdollisimman paljon "oikeasti" realismin tavoittamiseksi.
Nyt on selvinnyt sekin, että innoitusta haettiin vuoden 2014 pelistä Alien: Isolation. Kauhu on se homman nimi.
"Alien: Isolation was kind of what made me see that Alien could truly be terrifying and done well today. I played it a few years after it came out. Don't Breathe was coming out. Or was I waiting for Don't Breathe to come out, and I was playing the game. That's why, at the time, I was like, 'Fuck, if I could do anything, I would love to do Alien and scare the audience again with that creature and those environments.' I was playing, and realizing how terrifying Alien could be if you take it back to that tone."
