With Oppenheimer, writer/director Christopher Nolan takes what many might consider an unusual route in examining the "father of the atomic bomb." Jumping between timelines, framing the narrative around two significant court hearings and shifting from black and white to color, this isn't your standard historical biopic. And yet it is, surreally using its subject's life to explore deeper, further reaching consequences that linger to this day. Adapted from the 2005 biography "American Prometheus" and clocking in at a gargantuan three hours, Nolan doesn't hold back in examining the string of events surrounding disgraced American physicist J. Robert Oppenheimer's eventual loss of national security clearance in 1954.

While a fair amount of the story's energy is poured into the actual development of Oppenheimer's weapon of mass destruction, it's primarily gripping prologue, preparing us for the controversy to come. It isn't until his idea becomes a reality that he discovers the moral complications and lack of control he'll have over its use. You can chalk this up to hubris or naivety as his concerns aren't merely dismissed, but savagely ripped apart, leaving the renowned physicist's reputation smeared. History may have partially corrected that, but the most unsettling aspect is how it happened to begin with.

It's 1926 when American-born 22 year-old theoretical physics student J. Robert Oppenheimer (Cillian Murphy) studies at Cambridge before completing his PhD in Germany and returns to the states to teach quantum physics in California. While on the West Coast he befriends a group of U.S. Communist Party members, getting entangled in romantic relationships with troubled psychiatrist Jean Tatlock (Florence Pugh) and his eventual wife, biologist Kitty Puening (Emily Blunt). But everything changes once he's approached by General Leslie Groves (Matt Damon) in the midst of World War II.

With the Nazis and Russia suspected of working on a nuclear arms program, Oppenheimer is recruited by Groves in 1942 to lead the Manhattan Project dedicated to developing an atomic bomb. Joined by a team of scientists including good friend Isidor Isaac Rabbi (David Krumholtz) and the brilliant but disagreeable Edward Teller (Benny Safdie), Oppenheimer and his crew work around the clock in Los Alamos, New Mexico to prepare for a dangerous test detonation. As Oppenheimer's consumed with guilt over President Truman's (Gary Oldman) decision to bomb Japan into surrender, longtime rival and Energy Commission chairman Lewis Strauss (Robert Downey Jr.) schemes, pulling political strings to sideline the scientist.  

Non-linear as the film's structure appears, it actually follows a strict chronology that begins with Oppenheimer's academic years and continues through Los Alamos and beyond. There's a lengthy emphasis on his education, marveling under the learning tree of intellectual idols like Kenneth Branagh's Nobel winning physicist Niels Bohr. These early scenes, along with his personal troubles with wife Kitty and unhinged mistress Jean seem off-putting at first, but it adds up, as does his affiliation with communists. Nolan's pretty even handed with this, neither downplaying Oppenheimer's tangential involvement or how that association will be weaponized to later take him down. 

All roads lead to the 1945 Trinity A-bomb test, building up a huge amount of suspense and intrigue for the blast that clears the path for Truman's bombing of Hiroshima and Nagasaki. While the catastrophic event itself isn't depicted, the script doesn't shy away from questioning whether Japan would have  surrendered without such extreme measures. And no one's more ambivalent than the tortured Oppenheimer, who becomes painfully aware of the door he just opened and its horrifying ramifications. 

The film's most powerful scene comes when Oppenheimer delivers a speech to an audience full of scientists and military wildly cheering their hero for ending the war. But what he sees instead are bright, blinding lights and faces of burning flesh in the crowd that will haunt him long after the celebratory magazine profiles fade. Jennifer Lame's editing and Ludwig Göransson's score provide constant, palpable tension throughout, but never more than during this sequence, which signals the psychological battle he'll now be fighting within himself.

Supposedly, the feud between Mozart and Salieri in Amadeus served as Nolan's inspiration for Lewis Strauss's hate and jealousy fueled vendetta against Oppenheimer, which is mostly one-sided. By orchestrating a predetermined sham of a hearing for his opponent, Strauss ends up revealing more about the integrity of those testifying than the accused. But between Oppenheimer's womanizing and communist links, it's not hard to discredit him, even if a worse humiliation comes while meeting with Truman, who mocks his concerns. When given the choice of falling in line or getting out of the way, he picks neither, losing his country instead. 

Cillian Murphy has played his fair share of villains and creeps, but Oppenheimer, while eccentrically flawed and narcissistic, isn't exactly that, if only because his intense regret is enough to qualify him as having a conscience. But he still did what he did and spends the rest of his days grappling with it, leaving the gravest risk to humanity in the hands of a potentially irresponsible government.

Through that lens, it's easy to view Oppenheimer as a hopelessly reckless, but the pull of Murphy's performance is that he plays him as nearly impenetrable and impossible to read right up until the enormity of what's happened sinks in. And with his sunken, hollowed face and darting eyes, the eeriest aspect to his casting is how an actor with such an unusually unmistakable look manages to be a physical dead ringer for the man himself. 

Strauss' 1959 Senate confirmation hearing for Eisenhower's Secretary of Commerce position proves to be a referendum on the former shoe salesman's shady dealings and Oppenheimer's last shot at any kind of redemption. Downey's brilliance peaks here, revealing he was actually this good at being bad the entire time, only now allowing us to catch on. The rest of this loaded cast is packed with big names filling what would otherwise be considered small, throwaway roles under the guidance of a lesser director. Some are seamlessly interwoven into the plot's fabric while others are briefly written off until reappearing later to make massive contributions. 

Matt Damon steals a portion of the film with his gravitas as the hard-nosed, practical Gen. Groves while brief, strong turns also come from Josh Hartnett and Rami Malek as physicists Ernest Lawrence and David Hill, Jason Clarke as hearing attorney Roger Robb, Casey Affleck as military intelligence officer Boris Pash, and most notably, Alden Eidenreich as Strauss' unnamed fictional aide who becomes increasingly disillusioned with his boss. Blunt isn't given tons to do as Kitty, but she nails the heavily factual interpretation, right down to her pivotal testimony ripped directly from the transcripts. Pugh makes an even larger impression with far less screen time, bringing a desperate instability and magnetic seductiveness to Jean, who's constantly a step away from falling off the deep end.

With a fairly restrained use of CGI and an emphasis on more practical effects, the only small complaint is some questionable old age makeup in the last act that's still less distracting than any digitized approach, especially in a period piece. But the film deserves major credit for what's probably the best use of Albert Einstein (magnificently played by Scottish actor Tom Conti) we've seen in a historical drama. There's this clever mystery surrounding the professional bond he shares with Oppenheimer that requires both more and less unpacking than you'd initially assume. And that's especially true of their unforgettable final scene.  

Cold and detached, this is still surprisingly accessible, with everything locking into place for Nolan in ways it hasn't before. Plagued by anxiety and impending doom, we watch the scientist simmer from the inside, realizing his greatest innovation could very well destroy the world. And that enormous weight is thrust onto viewers, making Oppenheimer a challenge to fully absorb in just a single watch, where you can only begin to unravel its numerous implications.
