Emily Blunt Refuses to Use AI in Steven Spielberg’s New Sci-Fi Thriller ‘Disclosure Day

Emily Blunt rejected a proposal from director Steven Spielberg to use artificial intelligence (AI) to develop the alien language for her role in the film “Disclosure Day,” according to Entertainment Tonight. Blunt instead manually created the character’s clicking and humming sounds through independent experimentation and sound booth recordings.

The sci-fi thriller debuted on June 13, 2026, featuring a cast that includes Josh O’Connor, Colin Firth, Colman Domingo, and Eve Hewson.

How did Emily Blunt create the alien voice in Disclosure Day?

Blunt developed the audio components of her character’s language by experimenting with sounds in her bathroom, according to Entertainment Tonight. She recorded various iterations and sent them to Spielberg for review.

The process involved a mix of clicking, humming, doing weird Barry White sort of low singing mixed with clicking with Morse code sounds, Blunt told the outlet. She noted that Spielberg wanted the final result to sound mathematical rather than terrifying.

The final audio heard in the film consists of layered noises Blunt recorded in a professional sound booth.

Why did Emily Blunt refuse the offer to use AI?

Blunt declined the technology after Spielberg suggested AI could be used to perfect the clicking noises of the alien character. She told Entertainment Tonight, I feel confident I can make some weird noises.

This decision aligns with Blunt’s broader skepticism of AI’s role in the arts. In a September 2025 interview with Variety, she expressed alarm after learning 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 further described AI as a very scary bubble to poke your head inside during an April 2026 conversation with USA Today. She compared the presence of such technology in a home to having a drug dealer in your house that doesn’t pay rent, specifically referencing the impact on her children’s independence and internet access.

How is Hollywood responding to AI integration?

The entertainment industry remains divided over the adoption of AI. Some production houses use the technology to reduce costs and accelerate production timelines, while others protest its implementation.

Critics within the industry argue that AI threatens to displace human workers, devalue artistic creation, and utilize an actor’s voice or likeness without their explicit consent.

To counter these risks, several high-profile figures have sought legal protections for their personal brands. According to Business Insider, the following individuals have filed for trademarks to protect their likenesses or iconic phrases:

• Matthew McConaughey
• Taylor Swift
• Lionel Richie

Blunt’s refusal to use AI for “Disclosure Day” represents a practical application of this industry-wide tension, prioritizing human performance over algorithmic optimization in a high-budget studio production.
