Oppenheimer

Christopher Nolan’s Oppenheimer arrived in the summer of 2023 and did something that shouldn’t have been possible. It turned a three-hour, R-rated biographical drama about a theoretical physicist into one of the biggest box office events of the year, earning close to a billion dollars worldwide. More impressive than the money is the fact that it earned that audience without explosions every ten minutes or a single superhero. This is a film built almost entirely on dialogue, performance, and the weight of history.

It follows J. Robert Oppenheimer from his early days studying quantum physics in Europe through his recruitment to lead the Manhattan Project at Los Alamos, and into the painful political fallout that followed. Nolan structures the story across two interweaving timelines, one shot in color from Oppenheimer’s subjective perspective and the other in black-and-white from the viewpoint of Atomic Energy Commission chairman Lewis Strauss. The approach is disorienting at first and deeply rewarding once both threads converge. Community reception has been overwhelmingly positive, with the film sweeping seven Academy Awards including Best Picture, Best Director, Best Actor, and Best Supporting Actor.

Oppenheimer’s Performances Elevates Everything

Cillian Murphy anchors every frame of this film, and the performance is something special. He’s in virtually every scene across three hours, and the range he covers is remarkable. There are moments of quiet intellectual hunger, flashes of arrogance, deep romantic recklessness, and a creeping dread that never fully leaves his face once the consequences of his work become clear. He won the Academy Award for Best Actor, and the consensus is that he earned it. This is not a loud, showy performance. Murphy does his most devastating work in the silences, in the way his face shifts when the full weight of what he’s built starts landing.

Robert Downey Jr. matches him from the opposite direction. Playing Lewis Strauss, the bureaucrat who maneuvers to destroy Oppenheimer’s reputation, Downey delivers what many consider his best work in years. He abandons the winking charisma that built his career and replaces it with tight-lipped resentment and political calculation. His Best Supporting Actor win felt inevitable by the time awards season arrived. The dynamic between Murphy and Downey gives the film its spine, two men locked in a conflict where the real weapon isn’t nuclear but procedural.

Beyond the leads, the ensemble is absurdly deep. Matt Damon brings unexpected warmth and humor as General Leslie Groves, the military overseer of Los Alamos. Emily Blunt makes Kitty Oppenheimer sharp and formidable, particularly in a late courtroom scene that crackles with barely contained fury. Josh Hartnett, Casey Affleck, Rami Malek, and others cycle through with brief but memorable turns. Few films pack this much talent into this many roles and still manage to give each performer something to do.

Technically, the film operates at a level that’s hard to overstate. Cinematographer Hoyte van Hoytema shot on IMAX 65mm and large-format 65mm film, including the first-ever use of IMAX black-and-white film stock. The result looks stunning, giving every frame a density and texture that digital photography rarely matches. Ludwig Goransson’s score is a major contributor to the film’s power, building from anxious violin patterns into something enormous before cutting to total silence at the moment of the Trinity test detonation. That silence, after nearly two hours of escalating tension, is one of the most effective choices in the entire film.

And then there’s the Trinity test, which has become iconic. Nolan used practical effects rather than CGI to create the explosion, and the decision pays off. There’s something visceral about knowing you’re watching real fire and real light rather than pixels. Combined with Goransson’s score and Murphy’s face, it’s the centerpiece the entire film builds toward, and it delivers.

Where Oppenheimer Stumbles

The most persistent criticism involves the film’s female characters. Florence Pugh plays Jean Tatlock, Oppenheimer’s lover, and Emily Blunt plays his wife Kitty. Both deliver strong performances with what they’re given, but what they’re given is limited. Pugh’s character exists largely in relation to Oppenheimer’s desires and decisions, with little exploration of her own beliefs or inner life. Blunt fares somewhat better, especially in the hearing scenes, but for a three-hour film with this much ambition, the women feel underserved. It’s a pattern that runs through much of Nolan’s filmography, and it stands out here because the rest of the character work is so strong.

After the Trinity test, the film’s third act has divided audiences more than any other section. Once the Manhattan Project concludes and the bombs fall, the film shifts almost entirely into political and legal territory. Oppenheimer’s security clearance hearing and Strauss’s Senate confirmation hearing dominate the final hour. Some viewers find this material gripping, a slow-burn revelation of how political machinery grinds down the people it no longer needs. Others feel it’s where the momentum stalls. The Strauss narrative in particular has been called too minor to justify the screen time it receives, especially compared to the world-altering stakes of everything that came before.

Sound mixing remains a Nolan trademark that not everyone appreciates. While Oppenheimer represents an improvement over previous films, there are still stretches where Goransson’s score or ambient sound overwhelms the dialogue. Nolan has stated he prefers using the original on-set audio rather than having actors re-record their lines in post-production, and the tradeoff means some conversations require real effort to follow. For a film this dense with information, that’s a frustration.

Perhaps most debated is the absence of Japanese victims from the film. Nolan’s camera never travels to Hiroshima or Nagasaki. The devastation is conveyed entirely through Oppenheimer’s guilt and imagination rather than through images of the actual consequences. Nolan has argued this reflects the film’s subjective approach, staying locked to Oppenheimer’s perspective. Some accept this as a valid artistic choice. Others see it as a significant gap, particularly given the film’s three-hour runtime and willingness to explore so many other threads in detail.

A Biopic That Refuses to Simplify

What matters most about Oppenheimer is what kind of film it chooses to be. This is not an action movie about building a bomb. It’s a character study wrapped inside a political thriller, and it trusts its audience to stay engaged through long scenes of scientists arguing, bureaucrats maneuvering, and a man slowly realizing that his greatest achievement might also be his greatest sin. That trust is remarkable for a film operating at this budget level, and the box office results suggest it was well placed.

Nolan’s nonlinear structure can be disorienting, especially in the first act when the two timelines haven’t yet established their own visual grammar. There are no title cards, and the jumps between decades are frequent. By the midpoint, most viewers have found their footing, but the early going asks for patience that not everyone is willing to give.

Should You Watch Oppenheimer?

If you have any interest in history, in the mechanics of how power works, or in watching a top-tier cast operate at full capacity, this belongs near the top of your list. It rewards attention. The nonlinear structure, the dense dialogue, and the three-hour runtime all demand that you meet the film halfway, and it repays that investment. Skip it if you’re looking for something fast-paced and conventional, or if dialogue-heavy political drama isn’t your idea of a good time.

The Verdict on Oppenheimer

Oppenheimer is one of the most ambitious biographical films in recent memory, built on a career-best performance from Cillian Murphy and technical craft that justifies every minute of its three-hour runtime. Robert Downey Jr. delivers his strongest work in years, the ensemble is stacked, and Ludwig Goransson’s score finds power in both fury and silence. A few underwritten characters and a hearing-heavy final hour keep it just short of flawless, but this is the rare blockbuster that trusts its audience completely and gets rewarded for it. It earned seven Academy Awards for good reason.
