Emily Blunt Leads Star-Studded London Premiere for Steven Spielberg's 'Disclosure Day'

Emily Blunt made her mark on the red carpet Thursday evening as the cast and filmmakers of Disclosure Day descended on CineWorld IMAX Leicester Square in London for the film's UK premiere.

The 43-year-old Oscar-nominated performer walked alongside her co-stars Josh O'Connor, Colin Firth, and Colman Domingo, who all turned out for the June 4 event. The ensemble also included Eve Hewson, Henry Lloyd-Hughes, and Wyatt Russell representing the cast side of the evening.

Behind the camera, director Steven Spielberg attended alongside producer Kristie Macosko Krieger and screenwriter David Koepp. The premiere drew notable family members as well, including Spielberg's wife Kate Capshaw and their daughter Destry Allyn Spielberg, Goldie Hawn in support of her son Wyatt Russell, and Blunt's sister Felicity Blunt accompanied by her husband Stanley Tucci.

Blunt commanded attention in a custom Stella McCartney gown paired with Hassanzadeh Jewellery. Colman Domingo and Eve Hewson both accessorized with pieces from Boucheron.

The film centers on a world-altering revelation, with its official description posing the question: "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 eight billion people. We are coming close to … Disclosure Day."

Disclosure Day arrives in theaters on June 12.
