Foundation season 3: release date, trailer, cast, plot and everything we know
The sci-fi epic is about to return

One of the next major sci-fi shows to hit screens is Foundation season 3, which has a release date creeping up on us, and thanks to recent announcements we know a lot about the show.
Foundation is an epic Apple TV Plus series about a powerful galactic empire whose demise is imminent, and the scientists, adventurers and colonists who try to create a faction (the Foundation) that'll outlast the oncoming dark age.
Foundation season 2 came out in 2023 and delays like the 2023 writers' strike, the departure of its showrunner during post-production and budget issues slowed down the return of its third season, which was at least greenlit. And soon it'll be here.
Here's how to watch Foundation if you haven't seen it, and we'd recommend doing so, as it's an exciting and twisty series. Sci-fi fans will enjoy the varied worlds, creatures and spaceships of the franchise, and you can appreciate them more through an interview we conducted with the show's visual effects supervisor here.
And once you're caught up on your watching and your reading, here's what we know about Foundation season 3.
Foundation season 3 release date
Apple has confirmed that Foundation season 3 will premiere on Friday, July 11.
Only one episode will release on that day, and new ones will release weekly all the way until Friday, September 12.
Foundation season 3 trailer
One month ahead of the Foundation season 3 premiere, Apple released a two-minute trailer for the new season:
This shows some interesting parts of the new season, like the powers of the Mule, some battle scenes and a team-up between the Foundation and the Empire.
Foundation season 3 plot
Apple has confirmed the plot and setting of Foundation season 3.
The show will take place 152 years after the Foundation season 2 finale. In this time the Foundation has become a powerful force in the galaxy, while the Cleon's empire has dwindled.
However these two powers have to put aside their differences and forge an alliance to put up a resistance to a dangerous new enemy: mind-controlling warlord The Mule, introduced in season 2.
Apple has teased that major characters could die in The Mule's campaign to dominate the empire.
Foundation season 3 cast
Certain characters are present in first-look imagery for Foundation season 3, so we know they'll be back:
- Jared Harris as Dr. Hari Soldon
- Lou Llobell as Gaal Dornick
- Lee Pace as Brother Day
- Terrence Mann as Brother Dusk
- Cassian Bilton as Brother Dawn
- Laura Birn as Demerzel
- Pilou Asbaek as The Mule
Mikael Persbrandt played The Mule in season 2 but Pilou Asbaek plays the role for season 3.
Beyond that list, we'll likely have to wait until the series comes out to meet any new characters.
And what about other recurring characters from past seasons? Given the time jump and certain deaths, it's unlikely.
