One of the coolest aspects of A Quiet Place is that the marketing (up until that final trailer that was stupidly dropped the week of release, at least) refused to show us the creatures, allowing us to see them for the very first time within the movie itself. And the creatures were pretty damn cool looking, making the wait to see them well worth it.
But what exactly are they? All the film really tells us is that they’re blind and therefore hunt by sound, but John Krasinski actually did flesh out their backstory during the pre-production process. In a chat with Empire, he revealed what he came up with.
“They are absolutely aliens. They’re from another planet,” Krasinski revealed. “Where I developed the idea of them and what I wanted them to look like was most alien movies are about takeovers, agendas, they’re a thinking alien creature, and for me this idea of a predator, this idea of a parasite, this idea of something that is introduced into an ecosystem [was interesting].”
He continued, “The idea behind all that is they’re definitely aliens and they’re an evolutionarily perfect machine. So the idea is if they grew up on a planet that had no humans and no light then they don’t need eyes, they can only hunt by sound. They also develop a way to protect themselves from everything else so that’s why they’re bulletproof and all these things. I had to make it make sense. I needed the rules of the monster to adhere as tightly to the rules of the family. The family, we had set up all these incredible rules, and I needed the monster to not just be convenient.”
“And the other idea was [the armor is] also the reason why they were able to survive kind of the explosion of their planet and then survive on these meteorites, because they’ve evolved to be bulletproof. Until they open themselves up to be vulnerable, they’re completely invulnerable.”
