Season 3 of The Lord of the Rings: Rings of Power — Confirmation, Cast and Everything to Know

Premiere Dates and Episodes

Season 3 is scheduled to begin on Prime Video on November 11, 2026. Four episodes are due to arrive on that date. The next two episodes are slated for November 18, with the final pair following on November 25. The season will have eight episodes in total.

New Faces Join the Cast

Jamie Campbell Bower, known for Stranger Things, will play Celeborn, Galadriel’s husband. Season 1 had suggested that Celeborn was dead, although the article notes this conflicts with the established Lord of the Rings story.

Eddie Marsan, whose credits include Ray Donovan, is set to portray Thráin. He is Prince Durin IV’s older brother and is reported to return to Khazad-dûm after their father dies.

War Shapes the New Season

The story moves forward five years from season 2, placing the War of the Elves and Sauron at its height. Sauron seeks to forge the One Ring as he pursues victory and control of Middle-earth.

Morfydd Clarke is expected to return as Galadriel, and Maxim Baldry is likely to reprise Isildur. Season 2 also confirmed the deaths of Waldreg and Bronwyn, played by Geoff Morrell and Nazanin Boniadi.

Renewal After Viewership Decline

The showrunners confirmed season 3 in late 2024, and Prime Video announced its development in February 2025. The renewal followed concerns that the series might not continue. Both earlier seasons received positive reviews, but reported viewership fell from 150 million to 55 million between seasons. The article says the series’ future remains uncertain until its numbers improve, despite the third season being confirmed.
