Mind Control and War Collide in Foundation Season 3

Apple TV+ released the official trailer for the third and final season of Foundation, its glossy, high-budget, and visuals-first adaptation of Isaac Asimov’s sprawling science fiction universe. The teaser, released on Wednesday, is set in the music of Leonard Cohen’s “First We Take Manhattan” and hints at a galaxy on the precipice of another crisis, a literal galaxy-spanning conflict on a scale well beyond anything the Foundation or the Galactic Empire have ever faced before, and the rise of one of Asimov’s most powerful and mysterious villains, the warlord and psionic criminal mastermind known as the Mule. The season is set to premiere on July 11, 2025, and air weekly episodes until September 12.

Foundation has remained fairly faithful to its namesake, but it has taken significant liberties with the source material. Seasons 1 and 2 were bookended by massive time jumps—138 years between the first and second seasons in particular—and set during what are called the First and Second Crises of galactic history. The First Crisis concluded the first season and saw a period of threat that would eventually lead to the Empire and its despotic Cleonic Dynasty taking over the galaxy. The Foundation, meanwhile, embraced its mission and began weaponizing religious messages to spread its influence. The Second Crisis introduced in the second season is likewise a major historical fulcrum in the novels, and in the show, it’s used to set the stage for another vast conflict between the Foundation and the Galactic Empire. As the second season began, the imperial capital was under threat from the Foundation, with the prospect of war very much on the horizon. A new colony of people with the potential for psionic abilities, known as the “Mentalics,” was also introduced in the second season and became the subject of significant focus.

Foundation Season 3 is set 152 years after the second season, a jump that lands the show in what is known in Asimov’s books as the Third Crisis. The official synopsis provided by Apple TV+ is brief but heavily summarizes: “The Foundation has become much larger and more powerful since the days of Hari Seldon’s earliest predictions, while the vast galactic empire he once sought to supplant, the Cleonic Dynasty, is beginning to show its age. Threatened by their insecurities and a relentless insurgency on the edges of known space, these long-standing enemies are brought together by a common and existential threat: a galactic warlord who is as fierce in battle as he is with his gift for mind control.”

The trailer opens on Hari Seldon (Jared Harris), who ominously intones, “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.” The camera cuts to Gaal Dornick (Lou Llobell), who has been on the rise in the second season, to more ominous effect as she states flatly, “We’re out of time.”

That mysterious villain is the Mule, who we see in the trailer but who is introduced cryptically. Played by Pilou Asbæk, The Mule wields a superpower of sorts, a power to make those around him break down their resistance and fall in line. “I can turn enemies into allies. Hate into love,” he says, matter-of-factly. “It only takes a little nudge.”

The trailer, as trailers do, contains a smattering of high-production-value action and explosions, battle, and cities falling to ruins in a brief instant. A new enemy that can coerce humanity into shifting its alliances in an instant, with apparent ease, sounds like it will be one hell of a threat, one that the Foundation will need every bit of the resources and power it has accumulated over the centuries to fight.

Season 3 also features many of the series’ primary players back, including Lee Pace, Cassian Bilton, and Terrence Mann as the three clones of Brother Day, Brother Dawn, and Brother Dusk, the primary figures in the imperial capital. Jared Harris returns as the key figure, Hari Seldon, and Lou Llobell returns as Gaal Dornick, as well as Laura Birn as the powerful, superintelligent Foundation operative and human-like robot Eto Demerzel.

In addition to the trio of Seldon clones and the reprise of those key characters, season 3 is also set to expand the cast. Alexander Siddig joins as Dr. Ebling Mis, a fervent devotee of Hari Seldon and a self-taught expert in the psychohistorical sciences; Troy Kotsur as Preem Palver, a leader of a planet-wide psychic colony; and Cherry Jones as the Foundation’s ambassador, Quent. Brandon P. Bell also joins as Han Pritcher, as does Synnøve Karlsen as Bayta Mallow, Cody Fern as Toran Mallow, Tómas Lemarquis as the flamboyant and possibly supernatural Magnifico Giganticus, Yootha Wong-Loi-Sing as Song, and Leo Bill as Mayor Indbur.

A World Tipping Toward Darkness

At its core, the trailer hammers home the promise of an existential, galaxy-wide threat. The ability to marshal the two warring sides of the Foundation and the Galactic Empire into an alliance is a tall order in its own right. The scale of the Mule’s powers, a mix of classic Asimovian ideas of military and bureaucratic might and wilder pulp sci-fi staples of telepathic control and manipulation, will only compound that. It’s not just whether these forces can stave off the Mule, but also whether, and how, Seldon’s psychohistory can survive the threat of a figure who can subvert reason itself.

Season 3, based on the title and the trailer, looks primed to step into those questions with more ambitious stakes than before, both in character and in the deepening world-building of Foundation’s take on this galaxy. The show airs weekly beginning on July 11.
