Emily Blunt looked as glamorous as ever as she joined a dapper Cillian Murphy at the Oppenheimer premiere in Paris on Tuesday.

Emily, 40, cut an elegant figure in a green satin gown with padded shoulders and a collared neckline as she made sure to capture attention.
She added a few extra inches to her frame with a pair of silver pointed stilettos and let her outfit do all the talking as she simply accessorised with droplet earrings.
The Mary Poppins star, who is playing physicist Oppenheimer’s wife Kitty in the biological thriller, styled her golden locks in glamorous waves.

The Peaky Blinders star styled his dark locks in a middle parting as he smiled for photographs alongside his A-list co-stars.
Cillian is playing Dr J. Robert Oppenheimer, the ‘father of the atomic bomb’, in the £81million blockbuster directed by Christopher Nolan.
Oppenheimer was the director of the laboratory which designed the atomic bomb during World War Two as part of the top-secret Manhattan Project.
The film is being adapted from the 2006 book American Prometheus: The Triumph And Tragedy Of J. Robert Oppenheimer, by Kai Bird and Martin J. Sherwin.
The book, which won the Pulitzer Prize, details Oppenheimer’s personal life and his time leading the Manhattan Project in the early and mid-1940s.
