The upcoming third season of Foundation, set to premiere on July 11, 2025, continues the epic narrative established in the previous seasons, taking place 152 years after Season 2.

This new season will explore the growth of the Foundation alongside the decline of the Cleonic Dynasty, introducing a formidable new antagonist, The Mule, a warlord who seeks to dominate the galaxy through force and mind control.

The series will consist of 10 episodes, with new episodes released weekly on Fridays until September 12, 2025.

Foundation is part of Apple TV+'s growing lineup of successful sci-fi shows, which also includes titles like Severance and Silo, and has been praised for its world-building, visuals, and storytelling.

A teaser trailer released on May 7, 2025, showcases The Mule, a telepathic mutant central to the storyline, hinting at a shift towards more action-oriented sequences.

The teaser promises explosive scenes, including spaceship battles and planetary bombardments, marking a departure from the series' previous focus on philosophical themes.

Returning cast members include Emmy Award-nominated actors Jared Harris, Lee Pace, and Lou Llobell, along with new additions like Cherry Jones and Troy Kotsur, enhancing the series' expansive narrative.

Pilou Asbæk will portray The Mule, taking over the role from Mikael Persbrandt, while Laura Birn reprises her role as the immortal robot Demerzel.

With an overall user rating of 7.6 out of 10 on IMDb, the series has captivated audiences and established a dedicated global fanbase since its debut.

Despite changes in leadership, including David S. Goyer stepping back as showrunner, the series continues to maintain its ambitious scope and vision.

Filming for Season 3 began in May 2023 but faced interruptions due to Hollywood strikes, ultimately completing production despite these challenges.

Foundation, based on Isaac Asimov's acclaimed novels, has helped redefine expectations for science fiction television, combining epic storytelling with complex themes.
