Emily Blunt could have let technology handle one of the strangest moments in Steven Spielberg’s Disclosure Day. Instead, she went into a sound booth and tried to make the alien sounds herself.
The actress described the choice during a new appearance on Hot Ones, where she discussed a pivotal scene from Spielberg’s upcoming sci-fi film. The sequence required her character to begin making sounds that do not seem human, and Blunt said artificial intelligence was one possible way to create the effect.
She did not want that option.

Blunt said the scene comes at the end of a “four-minute oner” as her character gradually begins to fall apart.
“There’s various ways you could do it,” Blunt said, according to TheWrap. “You could go the AI route, which I’m a bit terrified of. I thought I could make some real, really strange sounds.”
Rather than hand the moment over to a machine-generated effect, Blunt offered to record a range of unsettling sounds herself.
She Recorded the Alien Sounds Herself
Blunt said she created clicking sounds, humming sounds, consonant sounds, and unusual breathing noises for the scene.
The recording setup was physical as well as vocal. Blunt said one microphone was placed near her mouth and another near her throat so the sound team could capture the noises in a more unusual way.
The sound designer then used those recordings to build the final voice effect, according to TheWrap.
The Scene Connects to the Film’s Bigger Mystery
Disclosure Day stars Blunt in Spielberg’s return to large-scale alien science fiction. The film follows characters caught in a UFO-related conspiracy as they try to expose the truth about extraterrestrial life.
The Motion Picture Association described one trailer moment as Blunt’s character, a Kansas City meteorologist, delivering the weather before she begins speaking in an alien language. Josh O’Connor, Colin Firth, Eve Hewson, Colman Domingo, and Wyatt Russell also appear in the cast.
The film is scheduled to open in theaters on June 12.
The Choice Lands During Hollywood’s AI Debate
Blunt’s comments arrive while actors, writers, studios, and unions are still arguing over how artificial intelligence should be used in film and television.
Her answer was not a long industry speech. She kept it tied to one scene: AI could have helped create the sound, but she wanted the performance to begin with her own body and voice.
For a Spielberg alien movie built around fear, mystery, and human reaction, that choice gives one of the film’s strangest trailer moments a surprisingly practical origin.
