Emily Blunt Stuns Steven Spielberg With Otherworldly Voice for Disclosure Day

Steven Spielberg asked for alien clicks, and Emily Blunt basically said: cool, I got this. That was day one on Disclosure Day. Not AI. Not a plugin. Just Blunt in a booth making sounds you probably don’t want to hear alone at night. It ’s a tiny, very nerdy craft detail that also tells you a lot about what kind of movie this is and how Spielberg is approaching it.

The day-1 curveball: make the alien clicks yourself

Blunt told the story on Jimmy Kimmel Live: right before a key scene built around extraterrestrial communication, Spielberg gave her two options for the strange vocalizations her character uses — let AI handle it, or do it herself. She picked the human route, headed into a sound booth with Spielberg and his longtime, mega-decorated sound designer (as she put it, the guy has more Oscars than anyone), and spent her very first day on the film building the alien language by ear.

'We could do it one of two ways. We could go and do it with AI or you could do it yourself.'

'I feel very confident that I can make some very strange sounds.'

One more fun wrinkle: those clicks are not just background texture. Blunt said her character uses them on live TV. Given who she plays, that tracks — she’s a meteorologist who appears on-air, so when the weirdness hits, it spills straight into the broadcast.

Fans latched onto the story fast, partly because it lines up with Spielberg’s long-standing vibe: use the tools when they help, but don’t sideline actual performance. He has been pretty blunt himself about there being no real substitute for human creativity, with AI as a tool rather than the showrunner.

So what is Disclosure Day actually about?

At a recent Universal Pictures presentation, Blunt sketched out the shape of the movie: big-scale sci-fi about the moment we realize we are not alone, folded into a paranoid thriller and an emotional character story. The premise centers on a sudden, potentially world-changing contact — and what that does to people caught in the blast radius.

• Margaret: a TV meteorologist who suddenly develops extraordinary abilities
• Daniel Kellner: a cybersecurity administrator who teams up with her
• The pursuit: a top-tier, very shadowy government operation tries to stop them from getting the truth out
• The tone: extraterrestrial mystery meets conspiracy and paranoia, with a strong character core
• The broadcast angle: at least one set piece has Margaret using that alien clicking language live on air

Between the scale of the story and hands-on touches like Blunt building the language herself, Disclosure Day is being framed as Spielberg’s most ambitious original sci-fi in years. Early buzz has even tossed around the 'best in 20 years' line — bold talk, but the intrigue is real.

Personally, I love that they went with a human-made sound over an AI patch. It is creepier, and honestly, it is more Spielberg. If the alien language in the movie gives you chills, there’s a good chance you’re hearing Emily Blunt’s own vocal cords doing the haunting.
