Though John Krasinski’s comments to Empire may seem like a joke (and, in all fairness, it is pretty funny), this actually points to one of the coolest aspects of A Quiet Place.
We do not actually know if a sequel to A Quiet Place is happening just yet (though we have heard that ideas have been thrown around), but these are all ideas that could easily factor into another journey into this world.
The extraterrestrial monsters are not the only enemy in this universe; the sound is an enemy as well.
It creates a landscape in which any sound generated by a human can make for a fantastic set piece, and it leaves us wondering what an involuntary sneeze, a cough, or even a fart could do when trying to stay silent.
