The Jungle Cruise actress, 38, has reportedly been cast in the Oscar-nominated writer/director's next film Oppenheimer at Universal, according to Deadline and The Hollywood Reporter. Expected to debut in July 2023, the movie will tell the story of J. Robert Oppenheimer, the Manhattan Project mastermind who helped develop the atomic bomb.
Blunt will reportedly play Oppenheimer's wife, while the scientist will be portrayed by her A Quiet Place Part II costar Cillian Murphy. Murphy, 45, has made several movies with Nolan, including 2005's Batman Begins, 2010's Inception and 2017's Dunkirk.
A rep for Blunt did not immediately respond to PEOPLE's request for comment.

In May, Blunt explained on The Howard Stern Show that she can't envision herself ever playing a superhero on the big screen. "I don't know if superheroes are for me. They're not up my alley. I think it's been exhausted. We are inundated. It's not that it's only the movies, it's the endless TV shows as well," she said at the time.
The Mary Poppins Returns star did say that she would potentially be open to playing a superhero in the future, however, as long as it was "a really cool character."
"It's not to say that I would never want to play one. It would just have to be something so cool … and then I would be interested," said Blunt. "In general, I don't race to see superhero movies. They leave me feeling a little bit cold. I can't explain it. I can't get in there."
