How Foundation Season 3 Reimagines the Future

Apple TV+ released the official trailer for the upcoming third season of its Foundation, a high-budget, maximalist take on Isaac Asimov’s sprawling sci-fi book series. New episodes will be released every week, with the first airing on July 11, 2025, and the season finale on September 12.

Foundation has taken significant creative liberties with the books but retains their epic structure, with time skips spanning centuries at a time. The first season ended with a 138-year jump, while the second season spanned the events of a Second Crisis: a pivotal point where war loomed between the Foundation and the Galactic Empire. The Foundation had taken a more extreme turn, using weaponized religious rhetoric to expand its influence, and we met a shadowy colony of psionic individuals known as the “Mentalics.”

Season 3 leaps ahead by 152 years after the events of the second season and plants itself in what fans of Asimov’s Foundation trilogy know as the Third Crisis. The series’ description, courtesy of Apple TV+, notes that “the Foundation has grown in power and influence since its inception, while the galaxy-spanning Cleonic Dynasty struggles to maintain its authority.” Both of these formidable forces face a growing threat, both from within and without. They will be forced to ally against all odds, for an impending threat that might undo all they’ve built: the invasion of The Mule.

In the trailer, the voice of Hari Seldon (Jared Harris) echoes: “Centuries ago, when we predicted the end of the galaxy, the Foundation was founded to save the human race. But the coming darkness was always the turning point.” He is followed by Gaal Dornick (Lou Llobell), who has grown in power and influence over the first two seasons: “We’re out of time.”

The new antagonist, a warlord by the name of The Mule (Pilou Asbæk), is no ordinary villain, with disturbing power over human wills and emotions. “I can turn enemies into allies. Hate into love,” he says, as if reading your mind. “It only takes a little nudge.”

His origin is only hinted at, with explosions, battles, and cities in ruin in a montage that shows just how far The Mule’s influence has spread.

Lee Pace (Brother Day), Cassian Bilton (Brother Dawn), and Terrence Mann (Brother Dusk) return as the three cloned emperors, and Jared Harris (Hari Seldon) returns to his role as the title character. Lou Llobell reprises her role as Gaal Dornick, and Laura Birn returns as powerful and mysterious android Eto Demerzel.

A number of other actors have joined the cast, some to be recurring characters and others to join the main cast. Alexander Siddig joins the cast as the deeply devoted Dr. Ebling Mis, a self-taught psychohistorian and follower of Hari Seldon. Siddig has played several similar roles over his career, and may be best known for his role as the space medical doctor, Julian Bashir, in Star Trek: Deep Space Nine. Troy Kotsur is also joining the cast as Preem Palver, who will take the leadership of an entire planet of psychics. Cherry Jones has also joined the cast as Foundation ambassador Quent. Brandon P. Bell has joined the cast as Han Pritcher, Synnøve Karlsen is Bayta Mallow, Cody Fern is Toran Mallow, Tómas Lemarquis is flamboyant Magnifico Giganticus, Yootha Wong-Loi-Sing is Song, and Leo Bill is Mayor Indbur.

The Future is Frighteningly Uncertain

At the heart of Foundation is Asimov’s idea of “psychohistory”—a made-up science that employs mathematics and sociology to predict the long arc of history. This season, even that discipline may not be enough. With the Mule’s powers disrupting logical and emotional predictions, the fight may come down to not who has the most followers or resources, but who can just outlast the other.

Visually, the trailer is as big and ambitious as you’d expect from a series this high-budget. Space vistas, opulent civilizations, and high-stakes action define the look. But what sticks, after the big spaceships and explosions, is how it feels. The intensity of an alliance between arch enemies Empire and the Foundation. Will psychohistory survive the Mule’s attack on the very concept of reason? Is there any possible future where the galaxy does not descend into chaos?

Season 3 appears to have the stakes, character depth, and world-building to give those questions some fresh answers. With weekly new episodes beginning on July 11, fans of science fiction and TV on the big side of the budget are in for a treat.

Foundation has shown a will to take on big ideas, and the Mule’s arrival may pose a threat not just to the galaxy but to the very idea of predictability. If seasons 1 and 2 were about setting the pieces for Seldon’s plan in motion, this one may very well ask whether that plan can hold up in the face of the impossible.
