Foundation Season 3 Trailer Drops Ahead of July Premiere

Apple TV+ has released an official trailer for the third season of Foundation, the series’ high-budget, big-scope, visually ambitious take on Isaac Asimov’s classic science fiction novel series. The trailer highlights a teetering galaxy, an even bigger crisis to fix, and a new and legendary villain on the rise: Foundation’s new baddie, the Mule. The third season of Foundation is set to premiere on July 11, 2025, with new episodes airing weekly on Apple TV+ through September 12.

Fans of both Asimov’s books and the Apple TV+ series have been watching for clues about what this season might hold. The show, which has already veered from Asimov’s work in intriguing ways, still uses massive time jumps to structure its storytelling. Season 1 ended with a 138-year leap into the future, while Season 2 focused on the Second Crisis, a turning point for the show in which the first shots are fired for an open war between the Foundation and the Galactic Empire. The Foundation turned on its original mission, weaponizing its religious propaganda for its political ends. Meanwhile, a new mysterious group called the “Mentalics” was introduced, an entire colony of people with powerful psionic powers.

Season 3 will, however, leap even further into the future than that: 152 years after the events of season 2. This sets the season in what’s known in Asimov’s work as the Third Crisis. Apple TV+’s official synopsis suggests the Foundation is now much more established and powerful in this new era than it had been in its early days, while the once-powerful Cleonic Dynasty has begun to show signs of decline. Facing threats both internal and external, these two powers now find themselves reluctantly allied against an enemy capable of obliterating both of them: a warlord with a private military on a galactic scale and the power to directly influence the minds of others. He is known as the Mule.

The trailer offers up what we already know about the Mule, who is played by Pilou Asbæ k. Hari Seldon’s voiceover grimly intones the stakes for Foundation season 3, and the series as a whole: “Centuries ago, when we predicted the end of the galaxy, the Foundation was created to save the human race. But the coming darkness was always the turning point.” Following this, Gaal Dornick, who has emerged as an increasingly important player in the story, proclaims: “We’re out of time.”

The Mule, however, is no normal villain. The trailer introduces his disturbing power to shape human emotion and allegiance. “I can make enemies allies. Hate into love,” the Mule states with a kind of terrifying breeziness. “It only takes a little push.”

The trailer does not hold back on big-budget action sequences of the kind the series has already shown us, with explosions and violence on a huge scale, even entire cities collapsing under his sway.

In addition to Asbæ k’s Mule, we also see series regulars Lee Pace, Cassian Bilton, and Terrence Mann as the three imperial clones Brother Day, Brother Dawn, and Brother Dusk, returning to the series for season 3. Jared Harris also returns to reprise his main role as Hari Seldon, and both Lou Llobell and Laura Birn are back as Gaal Dornick and the powerful and mysterious Eto Demerzel android, respectively.

The cast of season 3, however, grows much larger. The new additions are notable ones: Alexander Siddig will play Dr. Ebling Mis, a zealot for Hari Seldon who is also a self-taught psychohistorian; Troy Kotsur will play Preem Palver, who has led a planet of psychics; and Cherry Jones as Foundation ambassador 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 the bombastic Magnifico Giganticus; Yootha Wong-Loi-Sing as Song; and Leo Bill as Mayor Indbur.

The Fate of Asimov’s Psychohistory

Foundation has, at its heart, always been about Asimov’s concept of “psychohistory,” a fictionalized science that uses mathematics and sociology to predict the overall, macro trends of history. But this season may see that model itself in doubt. With the Mule’s powers upending logic and emotional response in equal measure, this battle may no longer be about predicted probabilities. It’s about survival itself.

The trailer also makes it clear that Foundation is going to continue to deliver on its visual promises. Sweeping vistas of space, intricate civilizations, and high-stakes action fuel the trailer. But what hits here, as in the first two seasons, is the emotional heft of the fight to come. Is there any real way the Empire and Foundation could truly unite against a common foe? Will the series’ central concept of psychohistory be able to withstand the Mule’s attack on logic and reason itself? Is there any future of the galaxy that isn’t already doomed to be consumed by chaos?

Season 3 seems ready to address all of these questions, and with much larger stakes, deeper characters, and more sophisticated world-building. With a weekly release schedule starting on July 11, fans of both speculative fiction and epic-budgeted TV have a lot to get excited about.

Where the first two seasons of the show were about creating the pieces of Seldon’s plan, season 3 seems to be about whether that plan will be able to work against something that feels utterly impossible. The arrival of the Mule could threaten not just galactic peace but even the idea that the future can be predicted at all.
