The Mule Is Coming — and He’s Not Here to Negotiate

The streaming giant Apple TV+ has unveiled the official trailer for Foundation‘s third season, set to launch on July 11, 2025. The announcement and teaser of the highly anticipated TV series adaptation of Isaac Asimov’s sci-fi masterwork are not a spoiler for those who have been keeping track of the streaming service. Starring Lee Pace, Jared Harris, and Lou Llobell, the first season of Foundation introduced a re-imagined telling of Asimov’s grand science fiction saga of the Foundation, an independent research society formed to prevent an otherwise inescapable dark age in the galaxy. Season 2 is still in production, with a mid-July release.

Foundation Season 3 was officially announced in May by Apple TV+. The third season will receive weekly release, with the first episode airing on July 11, 2025, and the final one on September 12, 2025. The new trailer shows a shaky galaxy, and new crisis of galactic proportions, and, most importantly, the rise of the most dangerous and influential villain in Isaac Asimov’s novel series: The Mule.

Foundation Tries to Avoid Mistakes in Season 2

Foundation is a reimagined adaptation of Asimov’s “Foundation Trilogy,” but with significant and occasionally distracting changes from the source material. From its inception, the series adopted an approach that hopped over many centuries with storylines framed around increasingly distant future points. The biggest narrative time-jump of Season 1 came at the end of the finale, which jumped 138 years into the future. The second season likewise started 138 years into the future and was largely devoted to what Asimov termed the Second Crisis, a period of galactic upheaval as the Foundation and the authoritarian Galactic Empire moved ever closer to open warfare.

The Foundation had radicalized under the influence of the psychohistorian Hardin, militarizing religious texts to inspire, and with them, control and expand their territories. The other critical new development in the second season was the revelation of the “Mentalics,” a hidden colony of powerful psionically gifted individuals.

Season 3 opens 152 years after the end of Season 2 and firmly places it in what is known in Asimov’s original work as the Third Crisis period. In its official synopsis, the Apple TV+ team describes the third season as follows: “The Foundation is now more entrenched and powerful than ever, and the once-mighty Cleonic Dynasty is showing signs of fragility. As the Foundation and Empire stare at threats from within and without, they are forced to join forces to stop a powerful, destructive force: the warlord known as The Mule, who wields military might and the more terrifying power of mind control.”

In a chilling trailer voiceover, Hari Seldon (Jared Harris) intones: “Centuries ago, when we foretold the end of the galaxy, the Foundation was created to save humanity. But the coming darkness was always the turning point.” The trailer then cuts to Gaal Dornick (Lou Llobell), who is becoming increasingly important, who says urgently, “We’re out of time.”

The new villain, known as The Mule, played by Danish actor Pilou Asbæk, is no ordinary tyrant or warlord. The Mule has a disturbing capacity to manipulate the feelings and loyalties of those around him. “I can turn enemies into allies. Hate into love,” he purrs. “It only takes a little nudge.” The trailer, brimming with explosions, conflicts, and urban devastation, hints at just how dangerous and far-reaching the Mule might be.

Lee Pace, Cassian Bilton, and Terrence Mann will reprise their roles as the three imperial clones, Brother Day, Brother Dawn, and Brother Dusk. The key cast members from the second season will return: Jared Harris (Hari Seldon), Lou Llobell (Gaal Dornick), and Laura Birn (Eto Demerzel).

New to the Cast

Season 3 features a bevy of new cast members. Alexander Siddig joins as the ardent disciple of Hari Seldon and self-taught psychohistorian Dr. Ebling Mis; Troy Kotsur will lead a planet of psychic individuals as Preem Palver; and Cherry Jones will play the Foundation ambassador Quent. Brandon P. Bell joins as Han Pritcher, Synnøve Karlsen as Bayta Mallow, Cody Fern as Toran Mallow, Tómas Lemarquis as flamboyant Magnifico Giganticus, Yootha Wong-Loi-Sing as Song, and Leo Bill as Mayor Indbur.

A Future Foretold?

Foundation has always been powered by Asimov’s principal idea of “psychohistory,” or an academic discipline that employs the use of mathematics and sociology to determine future events on a large scale. However, this principle is under threat this time. With Mule’s superhuman powers over logic and emotions at play, this time, the war between emotions and logic might have no determinism. Even psychohistory might have to do some soul-searching.

Foundation has often been visually striking and epic in scale, delivering the big-budget feel it promises with its trailer. Sweeping vistas, wondrous planets, and lavish world-building are some of the epic visual delights in store. Most affecting is the emotional intensity and high stakes the trailer conveys of a potential showdown. Will the Foundation and the Empire come together? Will psychohistory make it through the Mule’s war on reason? Is there any future where the galaxy isn’t doomed to destruction?

Season 3 is shaping up to be the biggest so far. With the most ambitious stakes yet, a larger ensemble, and increasingly nuanced characters, the show has much to offer. Apple TV+ fans of science fiction and prestige TV series have much to look forward to with new episodes every week, starting July 11, 2025.

Foundation, through its last two seasons, has been about setting the pieces in place of Hari Seldon’s vision. Season 3 may be the big test of the plan, in the most Seldon-ian way possible: What happens when it all gets tossed in the face of the improbable and even impossible? The Mule’s arrival will threaten galactic peace—but perhaps also the very idea that humans’ future is predictable at all.
