Emily Blunt Stuns in Lilac Gown at Premiere

was every inch the leading lady as she arrived at the UK premiere of her film Disclosure Day at CineWorld IMAX Leicester Square in London on Thursday.

The British actress, 43, turned heads in a glitzy lilac corset gown as she joined her co-stars and star-studded attendees on the red carpet.

Emily, , dazzled in the strapless number and accessorised with a matching nail colour.

She was joined at the premiere by her glamorous sister Felicity Blunt and her brother-in-law Stanley Tucci.

The Devil Wears Prada star has earned acclaim for her 'incredible' turn in 's sci-fi epic.

The science fiction movie, out on June 12, stars Emily as Margaret Fairchild, a  City meteorologist and former journalist at the centre of a massive government conspiracy unraveling.

Emily's performance has been praised as 'incredible' as she stars alongside Josh O'Connor, , Eve Hewson and Colman Domingo in the David Koepp screenplay. 

It was first reported in April 2024 that Spielberg's next project would be a movie, with filming taking place from February to May last year in New York,  and Atlanta.

After a press viewing, one senior entertainment reporter wrote on X: 'I loved Disclosure Day. A dense roller-coaster ride blending chase film, love story, & mystery, all wrapped in sci-fi wonder. 

'It's Spielberg's best film in 20 years, filled w/ all the magic that makes his films so special, plus an all-time character/performance by Emily Blunt.'

Meanwhile, Collider's Editor-in-Chief, Steven Weintraub, wrote: 'In a shock to absolutely no one, Steven Spielberg has delivered another towering home run with Disclosure Day.

'I could go on and on about what I loved, but I was lucky enough to see the movie knowing almost nothing, and I strongly recommend you do the same. Stop watching the trailers. The one thing I will say: Emily Blunt is incredible. 

'I know big summer movies aren't usually the kinds of performances that get awards-season attention, but once people see what she does in this…'.

Elsewhere, film reporter Bill Bria also praised Emily's 'accomplished performance', and called the movie 'riveting, moving stuff.'

Rotten Tomatoes, meanwhile, branded Disclosure Day 'absolutely phenomenal', with their reviewer penning: 'I was hanging onto every word, captivated by the story as it all played out. 

'The score perfectly elevates every single scene. Part mystery, part Twilight Zone, something new entirely…WOW.'

Disclosure Day marks the 37th film that Spielberg has directed. 

A synopsis for the film reads: 'If you found out we weren't alone, if someone showed you, proved it to you, would that frighten you? 

'This summer, the truth belongs to seven billion people. We are coming close to… Disclosure Day.'

Spielberg's fascination with UFOs and outer space began in childhood, when his father woke him one night to watch the Perseid meteor shower from a field near their home in Haddon Heights, New Jersey. 

That early wonder inspired his first amateur film project at just 17, a 1964 feature-length sci-fi movie called Firelight, which he screened at a local Phoenix theater for family and friends, charging $1 per ticket.

That film seemed to set the director on the path about the unknown, as his 1977 Close Encounters of the Third Kind was released, followed by E.T. in 1982.

Both films were blockbuster hits, with E.T. becoming the highest-grossing film of all time for over a decade, surpassing Star Wars.

More recently, in 2005, Spielberg revamped the timeless War of the Worlds, which was one of that year's top films.

He has returned to his roots with Disclosure Day, which is based on his original story, but was penned by Koepp, who helped write Jurassic Park, Jurassic Park: The Lost World, and War of the Worlds.

In December, the first trailer offered a tantalizing glimpse into the story that promises to shake the world with revelations about life, while keeping much of the plot shrouded in mystery.

Clocking in at two minutes and seven seconds, the teaser opened with a haunting question: 'If you found out we weren't alone, if someone showed you, proved it to you, would that frighten you?'

Viewers are then thrust into Emily's world, as she portrays a meteorologist abruptly seized by a mysterious extraterrestrial force during a live broadcast. 

While Josh plays a determined man on a mission to reveal the truth about alien life to the world.

The trailer is packed with cryptic crop circles, high-speed chases, eerie creatures and chilling hints that humanity may not be alone in the universe.

Adding to the buzz, cryptic billboards appeared in Times Square and Los Angeles on December 10, bearing the message: 'All will be disclosed - Spielberg 06.12.26.'
