The Hollywood Reporter has confirmed that DeHaan will be joining the already impressive ensemble. The film will center on theoretical physicistJ. Robert Oppenheimer (Cillian Murphy), and his involvement with the creation of the atom bomb. According to a statement from Universal Pictures, it has also described the film as an “epic thriller that thrusts audiences into the pulse-pounding paradox of the enigmatic man who must risk destroying the world in order to save it.”
While DeHaan’s character details have been kept under wraps, the majority ofthe characters inOppenheimerhave been revealed. Florence Pugh and Benny Safdie will play Communist Party member Jean Tatlock and Hungarian Physicist Edward Teller, respectively, while other reports indicate that Matt Damon and Robert Downey Jr. are set to play Lieutenant General Leslie Groves, the director of the Manhattan Project, and Lewis Strauss, the chairman of Atomic Energy Commission. Emily Blunt is set to play Oppenheimer’s wife, Katherine Oppenheimer Vissering. Josh Hartnett’s and Rami Malek’s roles are still undisclosed.
While it of course is intimidating starring alongside Downey Jr. and Damon, DeHaan has proved that he can most definitely hold his own in a film. After his 2012 breakout in the found-footage science fiction filmChronicle, he would then go on to star in big blockbusters likeThe Amazing Spider-Man 2, in which he played that film’sversion of the Green Goblin, andValerian and the City of a Thousand Planets.
