Confirmed the origin of the creatures of 'A quiet place'

If you've already seen 'A Quiet Place' or think about seeing it this Friday (since the reviews have been incredible), you should know that it is not a horror movie to use and does not expose much to monsters, especially when it is about the terrifying creatures that stalk our protagonists. However, there are a couple of indications that these visionless predators may be of extraterrestrial origin and director John Krasinski confirmed this theory during an interview with Empire Magazine:

"They are absolutely extraterrestrial, from another planet. When I developed the idea of ​​them and what I wanted them to look like, I thought that most alien movies are based on thinking, intelligent creatures. I liked the idea of ​​a predator, a parasite, something that is introduced into an ecosystem. It was interesting. One of my favorite movies and I always see is 'RocknRolla', where they tell you all that history of crabs in the Thames. That's what I mean: the introduction of something that can not be contained. That's what interested me in the movie. "
