Zack Sharf Digital News Director Christopher Nolan and Cillian Murphy’s working relationship spans nearly 20 years and counting as the filmmaker has directed the “Peaky Blinders” favorite in six movies: Three Batman films, “Inception,” “Dunkirk” and “Oppenheimer.” Notably, however, the upcoming atomic bomb drama marks Murphy’s first time headlining a Nolan picture in the lead role. Murphy stars as theoretical physicist and “father of the atomic bomb” J. Robert Oppenheimer. In a recent interview with the Associated Press, the actor admitted he “was desperate” to lead a Nolan movie. “I have always said publicly and privately, to Chris, that if I’m available and you want me to be in a movie, I’m there. I don’t really care about the size of the part,” Murphy said. “But deep down, secretly, I was desperate to play a lead for him.”
