Hayley Atwell Wore Giambattista Valli Haute Couture To The ‘Mission: Impossible – The Final Reckoning’ Cannes Film Festival Premiere

If the brief was “main character energy,” Hayley Atwell understood it loud and clear for the Mission: Impossible – The Final Reckoning Cannes Film Festival premiere this evening.

With Angela Bassett, Pom Klementieff and Hannah Waddingham by her side, Hayley made sure her leading lady status was in no doubt wearing a bold red Giambattista Valli Spring 2025 Haute Couture gown that didn’t tiptoe into the spotlight — it stormed it.

Now, this won’t be everyone’s flavour. The oversized bow at the waist and the mermaid skirt might have some muttering about competing focal points, but after a string of sleek column gowns, this look delivered a jolt of unapologetic glamour. The silhouette was exaggerated, the hue was arresting, and it all screamed Cannes-worthy grandeur.

Topped off with Chopard jewels, Hayley gave us the kind of high-impact moment that the red carpet — and this franchise — deserved.

Stylist: Jenny Kennedy.
