Emily Blunt and Cillian Murphy step out at the Oppenheimer premiere in Paris

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

The co-stars both showed off their finesse as they joined their fellow cast members at Cinema Le Grand Rex to celebrate their much-anticipated biopic.

Emily, 40, looked elegant in a green satin dress with padded shoulders and a collared neckline as she made sure to turn heads.

She added a few extra inches to her frame with a pair of silver pointed stilettos and let her outfit do all the talking while simply accessorizing with teardrop earrings.

The Mary Poppins star, who plays physicist Oppenheimer Kitty’s wife in the biological thriller, styled her golden locks into glamorous waves.

She accentuated her striking features with lots of mascara and a touch of pink lipstick as she posed for the cameras.

Meanwhile, Irish actor Cillian, 47, cut a suave figure in a navy blue suit consisting of smart trousers and a fitted blazer.

He styled his smart ensemble with a beige shirt and matching tie, while finishing the look with patent black boots.

The Peaky Blinders star styled his dark locks into a center parting as he smiled for photos alongside his A-list co-stars.

Cillian plays Dr. J. Robert Oppenheimer, the ‘father of the atomic bomb’, in the £81 million blockbuster, directed by Christopher Nolan.

Oppenheimer was the director of the laboratory that designed the atomic bomb as part of the top-secret Manhattan Project during World War II.

The film is an adaptation of 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, chronicles Oppenheimer’s personal life and his time as leader of the Manhattan Project in the early and mid-1940s.

The movie is set to be released on July 21, and a whole bunch of the A-list cast flocked to Paris to celebrate its release on Tuesday.

Also present at the premiere was Matt Damon, who stars as Lieutenant General Leslie Groves – an engineer who directed the Manhattan Project.

Matt, 52, looked smart in a smart navy blue suit, which he styled with a plain white T-shirt and brown boots.

He styled his silver locks in a sleek style and appeared to be jovial as he smiled and waved at photographers.

The cast also includes Florence Pugh – who plays Oppenheimer’s mistress – Kenneth Branagh, Robert Downey, Rami Malek and Josh Hartnett.

Gary Oldman would also have a cameo in the epic as President Truman.

Truman met Oppenheimer after the bombs were used in 1945, killing 200,000 people, and Oppenheimer said he felt he had blood on his hands.

Such pangs of conscience were of little use to Truman, and he dismissed him as a “crybaby scientist.”

The cast have been busy promoting the film together for the past few weeks and Robert Downey Jr – who plays – Lewis Strauss recently shared a photo of them all.

He posted the picture of himself with Matt, Cillian, Emily and John Krasinski, even hinting at a possible cameo from Emily’s husband.

“Connecting with my Oppenheimer castmates… wait, is that a Krasinski photobomb or maybe there’s a surprise cameo???” he captioned a photo shared on his Instagram on Sunday.
