Asimov’s Legacy Reimagined in Foundation Season 3

Apple TV+ has released the first trailer for Foundation season 3, its expensive, visually flashy adaptation of Isaac Asimov’s Foundation series. The trailer teases an unraveling galaxy, a new crisis on a truly galactic scale, and the arrival of one of Asimov’s most powerful and most mysterious villains yet: The Mule. Season 3 of Foundation is set to premiere on July 11, 2025, with new episodes dropping weekly through September 12.

Foundation has long taken some significant liberties with Asimov’s source material. But the show’s biggest departures have come in its timeline. Season 1 ended with a 138-year time jump forward. Season 2 followed a single new generation of Foundation members in what’s become known as the Second Crisis—a major inflection point in Foundation history in which a new war between the Foundation and the long-dominant Galactic Empire looms on the horizon, but the Foundation itself has gone a darker path, weaponizing religious fervor to exert its influence over ever more worlds. Season 2 also introduced a new “Mentalics” colony whose members have uncanny psionic powers.

Season 3’s story begins another 152 years after the end of season 2, placing the narrative in what fans of Asimov’s Foundation books and stories know as the Third Crisis. According to an official synopsis from Apple TV+, “The Foundation is much larger, more widespread, and more influential than it has ever been, and the once-terrifying Cleonic Dynasty is starting to lose its grip. But when faced with a shared, galactic-level threat, these two former rivals are the galaxy’s only hope.” That new force comes in the form of “The Mule, a warlord armed with brutal militaristic might and the power to bend minds to his will.”

The trailer begins with a foreboding voice from Hari Seldon (Jared Harris): “Centuries ago, when we predicted the fall of the galaxy, the Foundation was created to save humanity. But the coming darkness was always the turning point.” A grim message from Gaal Dornick (Lou Llobell) follows: “We’re out of time.”

The Mule himself, played by Pilou Asbæk, is a character more powerful and more disturbing than any the show has had yet. “I can turn enemies into allies,” he tells the viewer with a simple, quiet menace. “Hate into love. It only takes a little nudge.”

The trailer is action-heavy, featuring explosions and battles and sprawling cities being knocked to their knees. It’s difficult to say just how much reach the Mule will have, and what his arrival means for this galaxy’s version of a prolonged Cold War.

Lee Pace, Cassian Bilton, and Terrence Mann will return as the three imperial clones, Brother Day, Brother Dawn, and Brother Dusk. Jared Harris and Lou Llobell will reprise their roles as Hari Seldon and Gaal Dornick, respectively, while Laura Birn also returns as the immensely powerful, enigmatic android Eto Demerzel.

Season 3, meanwhile, features a massive cast of new characters, including Alexander Siddig as Dr. Ebling Mis, a vocal disciple of Hari Seldon’s work and a self-taught psychohistorian; Troy Kotsur as Preem Palver, who leads a planet full of psychics; and Cherry Jones as Foundation ambassador Quent. Also joining the show is Brandon P. Bell as Han Pritcher; Synnøve Karlsen as Bayta Mallow; Cody Fern as Toran Mallow; Tómas Lemarquis as the flamboyant Magnifico Giganticus; Yootha Wong-Loi-Sing as Song; and Leo Bill as Mayor Indbur.

A Threat Against Prediction Itself

Psychohistory has been the secret beating heart of the Foundation series since the first episode. The fictional social science marries sociology and statistics, and mathematics, in order to predict the general patterns of human behavior on a grand scale. The crisis that the Foundation faces with the Mule this season, though, has ramifications against psychohistory itself. The Mule’s power manipulates human emotion and loyalty on an instinctual level. It could make psychohistory irrelevant. Can the Empire and the Foundation trust one another enough to unite? Can psychohistory stand against a being whose powers undermine the emotional instincts that psychohistory itself takes for granted?

It’s a tall order for season 3 to pull off. The trailer is sure to please fans who’ve been with the show since the beginning in terms of sheer visual spectacle. Lush space vistas and colorfully imagined worlds, and high-stakes action are the bread and butter of Foundation, and the trailer checks all of those boxes. But it’s what’s on the line emotionally that the trailer manages to get across. Can the Foundation and the Empire put aside their differences? Can psychohistory hold up against an enemy that’s attacking both logic and human instinct? Can there ever be a future in which the galaxy isn’t consumed by chaos?

Season 3 looks poised to answer those questions with as big a scope as ever, more complex characters, and new iterations of epic world-building that the Foundation books have inspired for generations. Season 3 begins July 11 with weekly episodes through September 12.
