Cillian Murphy opens up about challenges of playing J. Robert Oppenheimer and potential "Peaky Blinders" film

Cillian Murphy, celebrated around the world for his transformative performances, said he felt the weight of the responsibility and the challenges associated with portraying J. Robert Oppenheimer, the enigmatic father of the atomic bomb. 

Reflecting on the role, Murphy said that while he was familiar with Oppenheimer's role in developing the atomic bomb and the Trinity nuclear tests, the subsequent events of Oppenheimer's life were mostly new to him. 

"That whole aspect of his life and the hearing where he lost his security clearance and all of that, and how he kind of became vilified in American society, even though he had been this ... the most famous scientist in the world," Murphy said.
