At one point in Christopher Nolan's Oppenheimer, the father of the atomic bomb dons his iconic uniform — a fedora cap, a smoking pipe, a slightly over-sized suit — like Batman wearing his cape and cowl for the first time. It's a look that serves as a sort of armor against mere mortals, who he woos with a peculiar charisma, as well as the military and political bureaucracy he battles while leading the Manhattan Project. It's also a way for J. Robert Oppenheimer (played by Cillian Murphy) to ground himself as he wrestles with the major conflict around his work: Building an atomic bomb could help win the war, but at what cost to humanity?
Oppenheimer may seem like a curious project for Nolan: Since wrapping up his Batman trilogy with The Dark Knight Rises, he's thrown himself into increasingly complex projects (perhaps to atone for that disappointment). Interstellar was ostensibly a story about a man exploring the cosmos to find a new planet for humanity, but it also wrestled with personal sacrifices as his children aged beyond him.
