The bathtub scene with Emily Blunt was done in one take. According to John Krasinski, who is also Blunt's co-star and husband in real-life, as soon as he said, "Cut," Blunt immediately fell out of character and asked the crew, "What's everyone having for lunch?"
Actor-director John Krasinski has said that the single greatest compliment he received regarding the film, was in a tweet from the master of the horror story himself, Stephen King: "A QUIET PLACE is an extraordinary piece of work. Terrific acting, but the main thing is the SILENCE, and how it makes the camera's eye open wide in a way few movies manage" (6 April 2018).
The device Reagan wears is not a hearing aid, but a cochlear implant. This indicates that Reagan has a sensorineural hearing loss, which means her inner ear has sustained some sort of damage. The cochlear implant translates vibrations in the air into nerve impulses that the brain perceives as sound.
In an interview with the website SlashFilm, screenwriters Scott Beck and Bryan Woods revealed that Paramount Pictures originally intended to incorporate A Quiet Place (2018) into the studio's Cloverfield (2008) film franchise. As Beck said in the interview, "I guess it crossed our mind and we had spoken to our representatives about that possibility. It was weird timing, though, because when we were writing the script, 10 Cloverfield Lane (2016) was at Paramount. We were actually talking to an executive there about this film, and it felt from pitch form that there might be crossover, but when we finally took the final script in to Paramount, they saw it as a totally different movie." The screenwriters and director John Krasinski were ultimately relieved and grateful for Paramount to finally decide to allow them to make the film as a wholly original, stand-alone film, rather than to make it as a part of the Cloverfield film franchise, or any other film franchise for that matter. "One of our biggest fears was this [the film] getting swept up into some kind of franchise or repurposed for something like that," Woods added. "The reason I say 'biggest fear' - we love the 'Cloverfield' movies. They're excellent. It's just that as filmgoers, we crave new and original ideas, and we feel like so much of what's out there is IP. It's comic books, it's remakes, it's sequels. We show up to all of them, we enjoy those movies too, but our dream was always to drop something different into the marketplace, so we feel grateful that Paramount embraced the movie as its own thing."
John Krasinski almost turned down this film just as he was about to start work on the series Jack Ryan (2018). When asked by the producers if he'd be interested in appearing in a horror film, John replied that he did not do horror. But when he was presented with the premise about a 'family that can't make any noise and you have to figure out why,' he jumped on board straight away.
It was initially intended to leave the American Sign Language un-subtitled, believing the audience would understand the subtext of what was going on. Notably, the first trailer does not subtitle the signing. However, while editing the sequence where Regan argues with her father regarding her hearing aids, it was decided by the filmmakers that the sequence would have to be subtitled. Subsequently all use of ASL throughout the movie was subtitled.
The film was written by Scott Beck and Bryan Woods for Paramount, who submitted the script to John Krasinski to star. Krasinski's wife, Emily Blunt, also read the script and then wanted to co-star in the film. In addition to starring in the film, Krasinski is the film's director.
In an interview with E!, John Krasinski said, "I would love to direct Emily Blunt, [but] I'd rather act with Emily than direct. I don't know if I need that responsibility. She's so good and I'd be so scared to screw it up, but [I'd be] happy to be in scenes with her. That would be really fun. We're always up for doing something. It's just got to be the right thing...Give us a good one! I would love it!"
John Krasinski wanted his movie creature to be extra special and so discussed its general design and animations with Industrial Light & Magic (ILM) veteran visual effects wizard Scott Farrar, who'd been responsible for some of the memorable effects in such films as Cocoon (1985), Backdraft (1991) and Transformers (2007).
During the press tour of this film, fans have grown to love Krasinski and Blunt's chemistry as a real life couple. They eventually turned out to be many of the fans' top choice for Reed Richards and Sue Storm for the next Fantastic Four reboot, should there be any. Krasinski has expressed interest in pursuing the role.
Emily Blunt mentioned in interviews that she initially advised John Krasinski to cast Blunt's friend for the role of Evelyn Abbott. After reading the script (and loving it and the character), Blunt asked her husband to call the friend, fire her and cast Blunt instead.
The family name is Abbott. An abbot in Catholicism is the leader of a monastery. Abbots in monasteries, like Mr. and Mrs. Abbott, lead self sufficient communities which often support themselves through means such as farming, like the family in the film. Some monasteries are also silent, and so members will not wear shoes, will communicate infrequently with spoken language, and will pray together in silence like the family in the film.
The initial inspiration for Millicent Simmonds's deaf character came from an earlier character sketch in Scott Beck and Bryan Woods' unfinished screenplay "The Piper," which was an adaptation of the Pied Piper of Hamelin.
The trivia items below may give away important plot points.
During the scenes in Lee Abbott's (John Krasinski) basement, you can see a variety of newspaper articles on the wall, with one headline proclaiming that "[A] meteor hits Mexico with the force of a nuke", potentially alluding to how the creatures got to Earth.
Simmonds actually made John Krasinski cry on set with a suggestion to change an important part of the script. During the climactic scene between Lee and his kids (in the truck), the original script just had him signing "I love you." However, Simmonds suggested that he should sign "I've ALWAYS loved you," which made Krasinski cry.
That Blunt's character began suddenly bleeding a large amount of bright red blood was not a normal part of early labor, and was suggestive that something had gone wrong in her delivery, such as conditions where the placenta is damaged or begins to prematurely separate from the mother's body. These conditions can cause a lot of blood loss in the woman, the baby, or both. This explains both why Blunt's character lost consciousness after her delivery, and why there did not seem to be a problem with the baby crying right after delivery. The baby was born before entering the sound proofed room and was fairly quiet as he was being carried down to the room in Blunt's arms. The duration of silence from the baby after birth would be unusual unless there was a problem with the baby, such as blood loss, which was well explained by the sudden blood loss Blunt had in the bathtub.
In the advertising of this film, there are many scenes containing the youngest child, Beau (Cade Woodward), in which he's seen causing a lot of noise and more problems for the rest of the characters. It's unclear whether or not this was done on purpose or if some of his scenes were cut, but he is killed within the first ten minutes of the film.
The man in the woods who sacrifices himself out of grief over his dead wife is played by Leon Russom. Russom played a character in season 2 of Prison Break (2005) who did not speak either, although it was to prevent his voice from being recorded.
