Oppenheimer (2023) review

Oppenheimer is a three-hour film about a man sitting in rooms, and it is edited like an action film. Nolan's insight is that the most consequential events in twentieth-century history happened in conversations, and he stages them with the tension of a heist.

Structure and Editing

The film interleaves three timelines: Oppenheimer's academic rise and the Manhattan Project, the 1954 security hearing that stripped his clearance, and the 1959 Senate confirmation hearing for Lewis Strauss. The colour sequences are Oppenheimer's subjective experience; the black-and-white sequences are the objective record. That distinction is signalled clearly and maintained rigorously.

Jennifer Lame's editing is the film's engine. Three hours of dialogue-heavy material moves at a pace that never drags, and the film's use of montage — particularly in the early sections — compresses years of scientific history into minutes without losing clarity. The Trinity sequence is the film's most obvious set piece, and it is deliberately anticlimactic: the explosion arrives, then the sound arrives late, then the silence arrives, and the film gives the audience the full experience of the delay.

Murphy and the Ensemble

Cillian Murphy won Best Actor and the performance is the reason the film works. Oppenheimer is in nearly every scene and is frequently the least expressive person in the room, and Murphy communicates an entire inner life through his eyes. The film's final scene — the conversation with Einstein by the pond, which the film has been building to for three hours — depends entirely on Murphy's face, and it lands.

The ensemble is extraordinary and unusually deep. Robert Downey Jr. won Best Supporting Actor for Strauss, and the performance is a genuine departure. Emily Blunt's Kitty gets one scene of real fire and makes the most of it. Matt Damon's Groves is the film's most enjoyable presence, and the smaller roles — Benny Safdie's Teller, Josh Hartnett's Lawrence, Tom Conti's Einstein — are all sharply drawn.

Craft and the Trinity Sequence

Hoyte van Hoytema shot the film largely in IMAX and in close-up, and the choice to keep the camera on faces rather than on scale is what distinguishes it from Nolan's other work. The Trinity test was shot practically with real explosives and gasoline, combined with digital elements, and the sequence's power comes from its restraint: the film shows the explosion, then holds on Oppenheimer's face, and then delivers the sound.

Ludwig Göransson won an Oscar for the score, which is built around a single ascending violin figure that appears in almost every scene in some form. The sound design is equally meticulous — the film's use of silence and the famous foot-stomping sequence in the gymnasium are more effective than any conventional action cue. The film is technically superb in a way that serves its ideas rather than competing with them.

The Moral Argument

The film is careful to present Oppenheimer's position without endorsing it. He is shown as a man who understood the implications, argued for international control, and was destroyed by the political machinery he helped create. The film is also honest about his limitations — his treatment of Jean Tatlock, his refusal to take a clear public position at moments when it mattered, and his enthusiasm for the project while it was happening.

The film's final image is a series of visions of nuclear destruction layered over a handshake, and it is one of the most effective endings Nolan has written. The argument is not that Oppenheimer was guilty or innocent. It is that the world he made is the one we live in, and that the chain of consequence cannot be unmade by any subsequent regret. That is a more sophisticated position than most biopics attempt.
