Emily Blunt Steals Disclosure Day With the One Thing AI Can’t Fake

There are moments in filmmaking where the tech on offer is frankly mad, but some actors would still rather do it the hard way. Emily Blunt, for instance, spent a chunk of her latest project 'Disclosure Day' making noises straight out of cosmic horror – and she was determined not to let artificial intelligence anywhere near it.

'Disclosure Day': The Essentials

So, what's this all about? 'Disclosure Day' is poised to land in cinemas on 12 June 2026, and the cast alone is enough to get any film nerd sweating. We're talking Emily Blunt front and centre, joined by Josh O'Connor, Colin Firth, Colman Domingo, Eve Hewson, and plenty more – basically, a who’s who of modern British and American acting royalty.

The story itself comes from Steven Spielberg, and the screenplay is courtesy of David Koepp. Koepp and Spielberg are an old team, having previously put their names to 'Jurassic Park', 'The Lost World: Jurassic Park', 'War of the Worlds', and even that slightly baffling 'Indiana Jones and the Kingdom of the Crystal Skull'. You get the idea: if you want spectacle with a tinge of weird, they’re your go-to.

Emily Blunt v. The Robots

Early chatter about the film is, unsurprisingly, honed in on Blunt. Not just because she's good, but because in the trailers and sneak peeks there are bits where she appears to be overtaken by...something. She busts out a made-up language and sounds frankly unhinged (in a good way). On a recent episode of Hot Ones, Blunt let slip that the freaky voices were all her – no AI, no post-production trickery.

As Blunt put it:

'There’s various ways you could do it – you could go the AI route, which I’m a bit terrified of.'

Instead, they slapped microphones all over her mouth and throat and let her go for it herself. Real commitment, even if it does make you look an absolute fool in front of the crew. (Worth a reminder: these days, you could easily whack it into a program and get some generically menacing noises, but that’s not the point, is it?)

Why Not Just Use AI?

If you’re wondering why Spielberg and Blunt didn’t just push the easy button with artificial intelligence, that’s part of the story. Yes, you could get AI to spit out a load of alien garble, but the whole point is that human messiness – the struggle, the inventiveness – is what gives a moment its authenticity.

That’s filmmaking, in a nutshell: try every inventive thing under the sun, even if it would save time to let a computer do it. And fair play to Blunt, she wanted it to sound as unsettling and genuine as possible.

It’s not exactly a crusade against technology; after all, AI does have its uses in the industry (let’s be honest, sometimes effects departments are run off their feet). But in this case, Blunt’s rationale is pretty clear: if you can actually perform it, why wouldn’t you?

All About the Early Buzz

• The film is set for a 12 June 2026 release
• Emily Blunt leads a cast including Josh O'Connor, Colin Firth, Colman Domingo, and Eve Hewson
• Story by Spielberg, script by David Koepp
• Blunt refused to use AI for her more bizarre, possessed-sounding scenes – it’s all her, with microphones stuck to her skin
• Blunt admitted on 'Hot Ones' that AI made her nervous, so she opted for pure performance – and it paid off
• Early social media responses are already tipping Blunt for major awards, with some calling this her best screen outing to date

At this rate, if you want an example of what humans can still do better than algorithms, 'Disclosure Day' might be your next case study.
