Intergalactic War, Mind Games & Epic Stakes: Foundation Is Back

Fans of Isaac Asimov’s science fiction classic have an exciting, and potentially existential, new threat to look forward to with the third season of Foundation. The official trailer from Apple TV+ for the science fiction series drops viewers right into action with a new galactic crisis of catastrophic scale. We also get a glimpse of one of Asimov’s most mysterious and fearsome villains, The Mule, played by Pilou Asbæk.

Foundation season 3 will premiere on Apple TV+ on July 11, 2025, and air weekly episodes through September 12.

A high-budget, technically adventurous take on Asimov’s namesake novel, Foundation, tells the story of its iconic science fiction galaxy in a series of broad strokes, each season taking place over many years, if not centuries. The first ended 138 years after it began, and the second season watched as Hari Seldon’s Foundation redefined itself and expanded its influence into a galaxy seemingly on the precipice of collapse. The Second Crisis, which took up much of that second season, was defined by a foreboding, if as yet unannounced, war between the Foundation and the headstrong, deeply racist Galactic Empire. The Foundation threw off its nascent scruples about using religion to control whole worlds, and we were introduced to a secret colony of so-called “Mentalics,” or people with psionic mental abilities.

Season 3 of Foundation now leaps 152 years after the previous, situating the plot in what’s known as the Third Crisis in Asimov’s various works about the fictional “Empire.” In a new official synopsis from Apple TV+, we learn that “A more mature Foundation has deepened its roots in the galaxy since the first Foundation was established, but the once-almighty Cleonic Dynasty begins to show cracks.” With internal and external forces bearing down on them both, they are soon forced to set aside their differences against a threat that is rapidly coming to define the age: the rise of The Mule, a warlord with both a private army and the power to bend the wills of those around him.

The trailer for Foundation season 3 appropriately kicks off with a familiar voice, that of Hari Seldon (Jared Harris), providing a doomy prologue. “Centuries ago, when we predicted the fall of the galaxy, the Foundation was created to save humanity,” he begins. “But the coming darkness was always the turning point.” Gaal Dornick (Lou Llobell) follows with a more strident warning: “We’re out of time.”

The Mule, this new villain, has a very particular power over other people, a kind of ability to control or direct their emotions. “I can turn enemies into allies. Hate into love,” he muses in the trailer. “It only takes a little nudge.” The trailer is filled with conflict, explosions, and world-ending moments, all of which are likely to show the Mule flexing some of that power.

The core cast from Foundation will return, including Lee Pace, Cassian Bilton, and Terrence Mann as three genetically engineered clones—Brother Day, Brother Dawn, and Brother Dusk; Jared Harris as Hari Seldon; Lou Llobell as Gaal Dornick; and Laura Birn as Eto Demerzel, a powerful and mysterious artificial intelligence with ties to the Emperor.

Season 3 of Foundation has a new, expanded cast of notable players that Apple TV+ has announced already. The most prominent are Alexander Siddig as Dr. Ebling Mis, a man driven mad by following the teachings of Hari Seldon and who becomes a self-taught psychohistorian himself; Troy Kotsur as Preem Palver, the leader of a planet of psychics; and Cherry Jones as Foundation ambassador Quent. Other roles include Brandon P. Bell as Han Pritcher; Synnøve Karlsen as Bayta Mallow; Cody Fern as Toran Mallow; Tómas Lemarquis as the flamboyant and bombastic Magnifico Giganticus; Yootha Wong-Loi-Sing as Song; and Leo Bill as Mayor Indbur.

Saving the Galaxy Again?

Foundation has always stood on Asimov’s concept of “psychohistory” as a fictional, math-based predictive science of sociology and social planning. But it’s looking like that very model of human events is going to be called into question, as the mental powers of the Mule change both logical and emotional reactions to the point where the conflict might be one of survival first and strategic thinking second.

The trailer is a visual feast, with the size of the galaxy, its varied citizens, and the eye-popping action of huge space battles all on full display. Most striking, though, is the emotion on display, as something we recognize as a classic villain tells us that the very future we take for granted is under threat.

Season 3 looks to build on those emotional connections, and the world-building and fantastic storytelling that have come before it. Weekly episode releases will begin on July 11, and it’s clear that for fans of big-budget sci-fi and of Asimov’s original Foundation novel, this third season will not be one to miss.

If the first two seasons were focused on building all the pieces of Seldon’s plan, this is the one that asks the question of whether that plan can survive when faced with what is, on its face, the impossible. The Mule not only threatens galactic stability, but also the idea that the human race’s future can even be predicted at all.
