Emily Blunt took a very human approach to creating the alien language in Steven Spielberg’s new film “Disclosure Day.”
During her press tour for the film, Blunt said she refused Spielberg’s offer to use AI to perfect the clicking noises her character makes in the film.
“He said, ‘You know, we could do it with AI, or you could do it,'” Blunt told Entertainment Tonight earlier this month. “And I was like, ‘I feel confident I can make some weird noises.'”
Blunt said she experimented with sounds alone in her bathroom and would send different versions to Spielberg.
“Clicking, humming, doing weird Barry White sort of low singing mixed with clicking with Morse code sounds,” Blunt said. “I just tried everything. We sort of threw the kitchen sink at it, and I think he wanted it to sound mathematical and not too terrifying.”
She said the final version audiences hear in “Disclosure Day” is an accumulation of layered noises she recorded in a sound booth.
Spielberg’s extraterrestrial thriller, which debuted on Friday, also stars Josh O’Connor, Colin Firth, Colman Domingo, and Eve Hewson.
Although parts of Hollywood have embraced AI as a way to speed up production and save money, others have derided and protested the technology. Critics are concerned AI could displace human workers, use their likeness or voice without consent, and devalue art.
Blunt has, so far, been unimpressed by AI.
She was dismayed during a Variety interview in September 2025 when she learned about AI actor Tilly Norwood.
“That is really, really scary. Come on, agencies, don’t do that. Please stop. Please stop taking away our human connection,” Blunt told Variety.
In April, Blunt also said AI is a “very scary bubble to poke your head inside” while speaking to USA Today.
“My children don’t go online, and they’re young still. You’re kind of holding on to them by their ankles as they get older and want more independence,” Blunt said. “At some point, I’m sure they’ll want a phone — they’d probably like one now, and they’re not going to get one. It’s like having a drug dealer in your house that doesn’t pay rent or actually give you any of the good stuff.”
Blunt isn’t the only actor to criticize AI, and some have even taken legal action to protect their brand. Matthew McConaughey, for example, has secured several trademarks meant to protect his likeness and certain iconic phrases. Singers Taylor Swift and Lionel Richie have also filed trademark applications for their likenesses.
