Christopher Nolan adapts Kai Bird and Martin J. Sherwin’s American Prometheus into a three-hour epic that’s structurally audacious and emotionally devastating. The film cross-cuts between Oppenheimer’s pre-war Berkeley years, the Manhattan Project, and his 1954 security hearing — all rendered in IMAX 70mm with Ludwig Göransson’s pulse-tightening score.
Cillian Murphy gives the performance of his career as the conflicted physicist who builds the bomb and immediately regrets it. The supporting cast — Emily Blunt, Robert Downey Jr., Matt Damon, Florence Pugh — is uniformly strong. RDJ in particular reminds us he’s a great character actor, not just Iron Man.
Nolan’s approach is more interior than spectacular. The Trinity test sequence is rendered with eerie silence before the shockwave arrives — a structural choice that mirrors the moral weight of what’s just happened. Not a war movie. A guilt movie.
