What Is Einstein and Eddington About?
The premise of Einstein and Eddington in 303 words, with nothing given away. The full story follows below.
In the shadow of World War I, a continent scarred by conflict finds an unexpected meeting place in the quiet halls of academia. The film opens amid the muffled rumble of artillery and the hushed whispers of laboratories, where the very fabric of reality is being questioned. A restless yet compassionate British astronomer, Arthur Eddington, a conscientious Quaker wary of war’s moral toll, crosses paths with the enigmatic German physicist, Albert Einstein, whose mind drifts far beyond the trenches to the curvature of spacetime. Their initial interaction feels like a delicate experiment in trust, set against a world where scientific journals are censored and old alliances crumble.
The narrative paints a richly textured period drama, balancing the cold precision of equations with the warm, often turbulent humanity of its protagonists. The tone is contemplative yet charged, echoing the clatter of typewriters and the flicker of candlelight in war‑torn lecture rooms. Through subtle glances and lingering conversations, the film suggests that ideas can travel faster than bullets, hinting at a burgeoning camaraderie that defies national borders. The surrounding characters—fellow scholars, skeptical veterans of Newtonian tradition, and families caught in anti‑German sentiment—add layers of cultural tension without overt villainy, emphasizing the fragile hope that intellectual exchange can survive even the darkest hours.
At its core, the story is a meditation on the power of curiosity and the courage required to bridge divides. As Eddington wrestles with his pacifist convictions and Einstein faces the weight of his own groundbreaking insights, the audience is invited to ponder how personal bonds might ignite scientific revolutions. The film’s atmosphere is one of quiet intensity, where the looming eclipse serves as a metaphor for revelation amidst obscurity, and where the promise of collaboration hints at a future where the cosmos—and perhaps humanity itself—might finally be seen in a new light.

Spoilers ahead
In 1919, a solar-eclipse expedition on Príncipe becomes a centerpiece for a story that braids scientific boldness with the upheavals of war. The mission, led by David Tennant as Arthur Eddington, strands itself between the immediate aftermath of World War I and earlier tensions dating back to 1914, when Jim Broadbent—I mean jim-broadbent—Sir Oliver Lodge appoints Eddington as chief astronomer at Cambridge to defend Newtonian order while quietly engaging with the revolutionary ideas of Andy Serkis as Albert Einstein. In Berlin, Einstein is drawn back to the Prussian Academy of Sciences and becomes entangled in the war effort, a move that inflames national pride and scientific rivalry; his relationship with his cousin Elsa Jodhi May deepens as personal and professional stakes rise.
The film follows Eddington as a Quaker who cannot bear arms, balancing faith and duty while bidding farewell to William Marston Patrick Kennedy, who goes off to war. After a narrow miss with Marston’s train, Eddington returns to his lecture circuit, defending Newton in a time of upheaval, and offers shelter to the Müller family whose members are threatened by anti-German backlash. Meanwhile, Einstein’s marriage strains under the strain of his affairs; his wife leaves him as a wave of protests erupts against scientists who seem to ally with the war effort. Einstein himself recoils from a violent demonstration related to Fritz Haber’s gas experiments, ultimately refusing to renounce his German citizenship and declining to sign a manifesto that would align scientists with the war.
Yet the narrative keeps returning to the scientific thread. Eddington confronts a British ban on German scientific literature, which complicates his study of the planet Mercury’s orbit. He reaches out to Einstein for insight, a gesture that draws Einstein into a collaboration with Max Planck [Donald Sumpter], who consoles a bereaved colleague while continuing his work. Together, their theoretical line-up—grounded in relativity and the bending of light by gravity—begins to match planetary observations in a way Newtonian theory cannot. The pair’s exchange, carried through Planck, helps Eddington see a path forward despite censorship and suspicion at home.
Across the wartime toll, Eddington mourns losses—most notably the gas attacks that claim many lives at Ypres—yet this grief galvanizes him to defend a plural scientific community rather than surrender to fear. Lodge, whose own son lies among the dead, clings to Newton as a cosmic anchor, but Eddington cannot admit the depth of his sorrow, even as Einstein’s public outburst isolates him from his university. Einstein, increasingly exhausted, falls ill, and Elsa temporarily withdraws, yet the work persists. Einstein completes a theory of general relativity, outlining how gravity curves spacetime and how starlight bends, and passes his results back to Eddington through Planck. With renewed purpose, Eddington secures funding for the expedition to prove Einstein’s predictions, aided by allies like Dyson, despite Lodge’s initial opposition.
The Príncipe expedition finally proceeds, delayed only by weather, as Einstein briefly returns to his ex-wife and children before a climactic reckoning. Bringing back two photographs from the eclipse, Eddington compares them against photographs taken under normal conditions, presenting the data before Lodge and the faithful Winifred, the latter depicted here through Rebecca Hall. The result is not only a vindication of Einstein’s theory but a resurgence of faith for Eddington, who proclaims, in a moment of awe, that he can hear God thinking. The news ripples through the world’s press as Elsa makes her way back to Einstein, and a year later, Einstein visits Cambridge to reconnect with Eddington. In the closing shots, the film reflects on both scientists’ later paths: Einstein’s enduring fame and Eddington’s enduring obscurity, a testament to how science can illuminate the cosmos even as it unsettles the beliefs that people hold most dear. > I can hear God, thinking
