From Cillian Murphy’s performance in Peaky Blinders to Florence Pugh’s acting in Midsommar, discover the other films these actors have appeared in

July 19, 2023, marks a new age of cinema, with Christopher Nolan’s much-awaited Oppenheimer opening that day. The Oscar-nominated writer-director brings to screen his most ambitious movie yet—a sweeping, epic thriller that delves deep into the psyche of a singular American mind: the brilliant scientist behind the world-shattering invention of the atomic bomb that represented the total sum of human ingenuity.

Beyond the storyline, production, and direction is the cast, with each one a point of interest for many. The film won’t only bring you back to memory lane with the scenes and plot but the characters as well. If they look familiar, you’ve probably seen them in a different movie or show already.

Josh Hartnett plays the physicist Ernest Lawrence in the film. “I knew a bit about Oppenheimer, but not Lawrence and how he was instrumental in creating nuclear weapons and what is now our 21st-century dilemma,” Hartnett says. “He’s the most important and impressive historical figure from the 20th Century that I knew nothing about...Everything has changed because of this guy and his tinkering.”

But did you know? The actor is no stranger to big films that tackle the morality of war and military heroics.

In 2001, he played the character of an Army pilot in Michael Bay’s Pearl Harbor and an Army ranger in Ridley Scott’s Black Hawk Down.

Florence Pugh

In Oppenheimer, Florence Pugh is the intellectual, deep-feeling introvert, sensual, free-spirited, yet prone to bouts of melancholy Jean Tatlock. She was a Stanford-educated psychiatrist who had an intense yet tortured romance with J. Robert Oppenheimer.

To play Tatlock, the filmmakers cast the actress, whose performances in Black Widow, Midsommar and Little Women, which earned her an Oscar nomination, have made her one of Hollywood’s brightest young stars. 

Robert Downey, Jr

Robert Downey, Jr portrays Lewis Strauss, Atomic Energy Commissio’s founding commissioner in 1947. Strauss played a key role in shaping America’s post-war nuclear policy. 

The Oppenheimer opportunity arrived in the actor’s life at a moment when he was trying to be particular in choosing his next project after his blockbuster run playing the foremost avenger, the well-known and loved Iron Man, of the Marvel Cinematic Universe.

To play brigadier general Leslie Groves, the filmmakers recruited Matt Damon.

Groves made significant contributions to the work of building the atomic bomb. According to Damon, the appeal of working on Oppenheimer was in crafting an origin story for the world he’s known his entire life, formed from the fallout of the Manhattan Project. “I’m a child of the Cold War,” he says. “I grew up with the consequences of this piece of history. So, without a doubt, this is one of the most important stories of our time.”

Damon is known for his outstanding performances in Air, The Martian, and Good Will Hunting

In Oppenheimer, Emily Blunt plays the role of biologist and botanist Kitty Oppenheimer, who’s also the wife of J. Robert.

Blunt was intrigued by Kitty’s rejection of social convention or expectation. “Kitty is a character who doesn’t do small talk; she only does big talk,” Blunt says. “She’s complicated, volatile, bewitching all at once. What I really was drawn to with her is that idea of a woman who refused to conform to the sort of feminine ideal of the time, why you need to get married and have children and support your man and that’s your job and that’s all you’re allowed. She just had this defiance against the system that felt so modern.”

Blunt is known for her breakout role and scene-stealing performances in Devil Wears Prada and A Quiet Place (I and II), and Sicario where she plays formidable roles as well.

Cillian Murphy plays the film’s titular character, the Father of the Atomic Bomb. The appeal and challenge of playing Oppenheimer, Murphy says, was doing justice to the physicist’s immense intelligence and moral struggles. “We were always chasing after the complexity of Oppenheimer, as he was no simple man,” he adds.

We’ve already seen Murphy’s remarkable works in 28 Days Later, A Quiet Place II, Peaky Blinders, and his roles in Nolan’s films The Dark Knight trilogy, Inception and Dunkirk.

Also starring in the film is Oscar-winner Casey Affleck as Boris Pash, chief of Army counter-intelligence at the Presidio in San Francisco, Oscar-winner Rami Malek as David Hill, an associate experimental physicist, Matthew Modine as Vannevar Bush, head of the US Office of Scientific Research and Development, Oscar-nominee Tom Conti as Albert Einstein and Oscar-winning filmmaker and actor Kenneth Branagh as Nobel Prize-winning physicist Niels Bohr.
