Colman Domingo, Emily Blunt, and Josh O'Connor Grace Paris Premiere of 'Disclosure Day'

The ensemble cast of the upcoming sci-fi thriller made a glamorous appearance at the Grand Rex in Paris on Tuesday, June 2, for the film's premiere event.

Colman Domingo, Emily Blunt, Josh O'Connor, and Wyatt Russell walked the red carpet alongside director Stephen Spielberg and his wife Kate Capshaw for the highly anticipated first premiere screening.

On the fashion front, Blunt turned heads in a custom Alaia gown paired with Marco Bicego jewelry. O'Connor opted for a complete Dior ensemble, while Domingo accessorized with Robert Marc Eyewear sunglasses.

The thriller explores a provocative premise: what would happen if humanity received definitive proof of extraterrestrial life? The film's tagline poses the central 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 is set for theatrical release on June 12th.
