“We’re Out of Time”: Foundation Season 3 Trailer Is Here

Apple TV+ released the first trailer for the third season of its pricey, large-scale take on Isaac Asimov’s Foundation series.

Set to premiere on July 11 and streaming new episodes weekly through September 12, 2025, the latest installment of Foundation sees the galaxy on edge as a new cataclysm of almost unfathomable proportions looms. In a preview of the escalating galactic drama, the trailer offers a teaser of Asimov’s shadowy powerhouse antagonist, The Mule, whose ascendancy signals both an end and a new beginning.

Based on Asimov’s seminal 1950s science fiction novels, Foundation has not shied away from taking its liberties with the books. Spread over centuries, the series is defined by massive time jumps. Season 1 saw a 138-year jump into the future to the period covered in Foundation and Empire, the third book in Asimov’s Foundation series. The second season, meanwhile, was primarily focused on the Second Crisis: the period of upheaval around the midpoint of Asimov’s Foundation series. Faced with the threat of open war with the Galactic Empire, the Foundation takes a more extreme turn with its weaponization of religious fervor and influence. A new “secret colony” of psionically gifted “Mentalics” is also introduced.

Season 3, however, makes a jump 152 years forward in time, placing the story in a phase known as the Third Crisis in Asimov’s lore. By Apple TV+’s description, this phase has Foundation as a more deeply rooted and established power than it was in the books’ early days. The once-mighty Cleonic Dynasty, too, is beginning to feel the pressure, as it starts to crumble. Both internal and external forces, existential threats on both ends, they are thrown into an uneasy alliance in the face of the most dangerous thing of all: The Mule, a warrior with both unprecedented military force and the psychokinetic power to manipulate the human mind.

The trailer opens with Hari Seldon’s voice echoing a prophecy of doom: “Centuries ago, when we foresaw the collapse of our galaxy, we made the Foundation in the hope of preserving civilization. But the coming darkness was always the point of change.” Gaal Dornick, who has risen through the ranks to become a player in her own right, then cuts in with a sense of finality and panic: “We’re out of time.”

The Mule, a mysterious enemy with an ominous ability to rewrite the loyalties of humanity, will be played by Pilou Asbæk. In the trailer, Asbæk’s character speaks of his abilities with the measured chill of a horror show villain: “I can turn your enemies into allies. Hate into love.” He goes on. “It only takes a little push.”

Flashes of chaos ensue, as explosions, fighting, and entire cities erupting into dust suggest the scale of his potential.

Lee Pace (Brother Day), Cassian Bilton (Brother Dawn), and Terrence Mann (Brother Dusk) will return for the third season in their roles as the triplets who were created as clones. Jared Harris and Lou Llobell will reprise their roles as Hari Seldon and Gaal Dornick, respectively, while Laura Birn will also return as Eto Demerzel, the character’s mighty and shadowy self. While the long-form series narrative is fragmented by those time jumps, these core roles have remained remarkably stable throughout.

Foundation Season 3 also boasts an enlarged cast, with high-profile additions and characters introduced in the novels. Alexander Siddig (Game of Thrones) will play the role of Dr. Ebling Mis, a fervent believer in Hari Seldon and an autodidact psychohistorian. Troy Kotsur will portray Preem Palver, who leads an entire planet of psychics, while Cherry Jones will play a Foundation ambassador named Quent. Also joining the cast are Brandon P. Bell as Han Pritcher, Synnøve Karlsen as Bayta Mallow, Cody Fern as Toran Mallow, Tómas Lemarquis as Magnifico Giganticus, Yootha Wong-Loi-Sing as Song, and Leo Bill as Mayor Indbur.

A Galaxy on the Brink

Foundation’s premise is centered on Asimov’s psychohistory: a fictionalized mix of mathematics, history, and sociology that can predict the general outcomes of large historical movements. But even that idea, this season, is called into question. If the Mule can control human emotion with his powers, both the logic of psychohistory and the reaction to its predictions might be thrown into turmoil. The whole future of the series, in that regard, might be put on the line.

And it would seem as though the showrunners at Apple are well aware of that weight. While the teaser drops a lot of new information, in terms of what Foundation fans have come to expect from the books or series so far, visually, the trailer checks all the right boxes. Sweeping space vistas, beautifully rendered cultures, and epic action sequences define the landscape. But it’s also the emotional stakes of the plot that stand out in the trailer. An uneasy alliance of Empire and Foundation powers might hold the only key to the future. The idea of psychohistory and a future that can be predicted might be at risk. But there are just as many versions of the future where the galaxy does not fall into chaos, disunity, and suffering.

Season 3 will no doubt scale up the stakes even higher with more intricate characters and lavishly crafted world-building. With episodes dropping new every week starting July 11, 2025, sci-fi fans and subscribers to big-budget streaming TV alike have a lot to look forward to.

If the first two seasons were spent building the pieces in Seldon’s foundation, the new one seems to show whether that all holds up in the face of the truly impossible. As much as the Mule’s arrival threatens galactic peace, it also poses a threat to the entire idea of a knowable human future.
