“She can monologue with her eyes.”
As an added element, there’s no dialogue.
The tension and drama builds through a very physical performance by Dever.

“I had this idea for the character of Brynn.
“Then I had the idea of an alien movie.
In my brain, [the two plots] made sense together.

Duffield explains that he came up with the idea of the movie being speech-less pretty late in the game.
“I wrote that scene and subsequent scenes of Brynn having a breakdown because no one would help her.
Then I realized,I don’t think she’s talked in this movie yet.

And sure enough she had not.”
Duffield decided to make Brynn a literally voiceless presence, which he found surprisingly easy to do.
It felt like that rig just amplified her character,” he continues.
She’s not going to say, ‘It’s an alien in my house!’
Also, when you have Kaitlyn Dever, she doesn’t need to say anything.
She can monologue with her eyes in a really impressive way.”
The film’s visitors were digitally created in postproduction, a process the director found stressful.
“My first production was a very problematic and public disaster,” he says.
“I was kind like, well, maybe I should never write again.
I was so depressed about what a debacle that was.
Lionsgate called my reps and asked me to go meet onInsurgent.
“But then I feel like the movie’s meaning changed so dramaticallybecauseof Covid,” Duffield adds.
“I’m very proud that exists.
So, having tackled exploding teenagers and house-invading aliens, what’s next for the filmmaker?
“I have no idea,” he says.
“Part of it’s because we’re striking right now, there’s nothing that’s geared up.
I’m just as curious about that as anyone else!”
