Matt Damon and his Oppenheimer co-stars took Paris by storm on Tuesday when they enjoyed their new film’s premiere in the city.

What new film, we hear you ask? Oh, just a little summer flick called Oppenheimer.

The new Christopher Nolan film is the most anticipated release of the summer (Barbie aside) and sees 52-year-old Matt star alongside the likes of Cillian Murphy and Florence Pugh.

But on Tuesday night, Matt’s leading ladies were his daughters, who travelled to France to support their famous dad.

The A-lister posed alongside 24-year-old Alexia, Gia, 14, and 12-year-old Stella at the star-studded bash and even allowed his daughters to invite some pals along for their night out in the French capital.

Needless to say, Matt – who is also dad to Isabella, 17 – looked proud as punch while posing with his girls.

Later in the evening, Matt and his youngest daughter Stella were seen making their way home.

The dad-daughter duo made a quick dash towards a waiting car, with Matt looking typically suave and Stella looking cool in a black dress.

Matt’s new biopic follows enigmatic scientist J. Robert Oppenheimer (Cillian) who must risk destroying the world in order to save it through his invention of the atomic bomb.

The plot focuses on the American physicist and his role in the Manhattan Project.

The Project, which ran from 1942 to 1946, produced the first nuclear weapons – they were then used in the bombings of Japanese cities Nagasaki and Hiroshima.

Oppenheimer, who was head of the Project’s development, became notable for his chain-smoking, often alternating between cigarettes and a pipe.

Speaking this month about his preparation for the role, Cillian, who famously played heavy smoker Thomas Shelby in Peaky Blinders, said he’s been turned off ‘fake cigarettes’ entirely.

‘Cigarettes and pipes. He would alternate between the two. That’s what [killed] him in the end,’ the 28 Days Later actor said.

Oppenheimer died of cancer in 1967.

‘I’ve smoked so many fake cigarettes for Peaky and this. My next character won’t be a smoker. They can’t be good for you,’ he told The Guardian.
