1. There are real family photos of John Krasinski and Emily Blunt and their children used in the film.
Why not, ya know?
2. In the beginning of the film, in the store, most of the food on the shelves is gone...except for all the bags of chips.
Because they're too noisy to eat/open!
3. The actor who plays Regan, Millicent Simmonds, is deaf in real life.
Krasinski, who you probably know directed the film, said having a deaf actor play Regan was non-negotiable.
4. And Simmonds told Krasinski that she really enjoyed seeing how different their characters' signing was.
Krasinski explained to the Independent, "Millie pointed out that my character is very shut off and just wants to survive and his signing is very curt, it’s very small, it’s very immediate and direct. Emily’s character is all about, 'We can’t just survive, there has to be beauty in the world. We have to give a life to our children.' So she’s very warm and she’s bigger and she’s more affectionate in her signing."
5. The actor who plays Marcus, Noah Jupe, is actually British.
Flawless accent, kid.
6. And George Clooney was the one who recommended Noah to John Krasinski for the role.
Clooney had previously directed Noah in Suburbicon.
7. The bathtub scene was done in only one take.
"As soon as she [Blunt] was done, she asked what was for lunch," said Krasinski.
8. The film's sound editors created what they called "sound envelopes" to put the audience in the characters' shoes to "hear what they hear and how they might hear it."
Sound editors Ethan Van der Ryn and Erik Aadahl ironically worked on very ~loud~ films, like Godzilla and Transformers, respectively.
