Season 3's biggest hook is the full arrival of the Mule, the saga's most anticipated antagonist, played by Pilou Asbaek of Game of Thrones after only fleeting teases in earlier seasons.
The season leaps roughly a century and a half ahead, waking Gaal Dornick from cryo-sleep into a transformed galaxy, and brings in Oscar winner Troy Kotsur of CODA as the Mentalic leader Preem Palver.
Production weathered serious upheaval, including a pause and relocation and a change in day-to-day showrunning as creator David S. Goyer stepped back to an executive-producer role amid budget clashes. Even so, the season opened at a perfect Rotten Tomatoes score and was renewed for a fourth run.
Foundation Season 3 continues Apple TV+'s sweeping science-fiction epic, loosely adapted from Isaac Asimov's landmark novels about the fall of a galactic empire and the small band of scientists trying to shorten the dark age that follows. Developed by David S. Goyer, the series is one of Apple's most visually ambitious productions, spanning centuries and civilizations.
The season makes the show's largest time jump yet, leaping well over a century forward as Gaal Dornick (Lou Llobell) confronts the rise of the Mule, the saga's most fearsome villain, played by Pilou Asbaek. Jared Harris and Lee Pace return as Hari Seldon and the cloned Brother Day, with new additions including Cherry Jones and Oscar winner Troy Kotsur as the Mentalic leader Preem Palver.
Premiering in July 2025, the season became the best-reviewed of the series, opening to a perfect score on Rotten Tomatoes before settling around 91%, and a global streaming hit that earned the show a fourth-season renewal even after well-publicized creative and budget turmoil behind the scenes. Streaming on Apple TV+.
