Emily Blunt is “terrified” of AI and chose not to rely on it during a pivotal sequence in Steven Spielberg’s upcoming film “Disclosure Day.”

The Spielberg-directed sci-fi film follows a Kansas City TV meteorologist, played by Blunt, who is suddenly overcome by a mysterious extraterrestrial force while taping a weather segment live on air.

The actress told “Hot Ones” host Sean Evans in the show’s latest episode that the key scene features her character speaking in a non-human language. “It’s a four-minute oner that we shot that leads up to that moment where she’s gradually sort of disintegrating.” She went on to say, “There’s various ways you could do it. You could go the AI route, which I’m a bit terrified of. I thought I could make some really strange sounds.”

Instead, Blunt opted to record the sound organically.

“I said maybe I could come in and we’ll just do a range of weird sounds. And it’s what we did,” she said. “I did sort of the clicking sounds, I did sort of humming sounds, consonant sounds, breathing strange sounds.” Strategically placed mics allowed the sound team to capture everything they needed, Blunt said: “The sound designer went away and created that weird sound.”
