Lee Pace Confirms Foundation Season 4

Production on "Foundation" Season 4 is currently in full swing in Prague, Czech Republic, as confirmed by star Lee Pace. The actor revealed he is on set, shooting a season that introduces "a whole new dimension" and expands the story significantly. Filming commenced around January 5, 2026, with an extensive schedule planned for over 120 days, all within the Czech Republic. This marks the first time an entire season will be shot exclusively in the country.

Pace, who portrays Brother Day, is also taking on a producer role for Season 4, allowing him creative input. The series, based on Isaac Asimov's novels, chronicles the fall of a Galactic Empire and the efforts to shorten a coming dark age. It has garnered acclaim for its scale and intricate plotting, becoming a flagship original for Apple TV+.

The renewal for Season 4, announced before the Season 3 finale in September 2025, underscores Apple's dedication to the ambitious project. Co-showrunners Ian Goldberg and David Kob are leading the new season, with original creator David S. Goyer remaining as an executive producer. Key cast members like Jared Harris and Lou Llobell are expected to return.

Filming in Prague utilizes local studios and locations to depict various worlds and settings. The extended 120-plus-day schedule allows for detailed visual effects work, contributing to the series' distinctive look. While Apple TV+ has not announced a release date, with principal photography likely concluding around May 2026, a 2027 premiere is anticipated, following the typical two-year cycle between recent seasons.

The decision to base the entire Season 4 shoot in the Czech Republic reflects logistical efficiency and Apple's commitment to high production values. The ongoing filming in Prague continues to bolster the city's film industry, reinforcing its status as a key European production hub. Pace's confirmation has generated significant excitement among fans speculating about future plot directions.
