Production updates from November 2024 confirm that filming is progressing well, with a tentative release window in late 2025.

1. Daniel Diemer as Tyson

The biggest new addition is the casting of Canadian actor Daniel Diemer as Tyson, Percy's cyclops half-brother and son of Poseidon. Diemer's casting was officially announced at San Diego Comic-Con (SDCC) 2025, where a first look at the character was revealed.

3. Vance as Zeus

Following the tragic passing of Lance Reddick, who portrayed the King of the Gods in Season 1, the role of Zeus has been recast for Season 2. Vance, a talented actor known for his stage work and television appearances, will take over the Olympian role. This recasting is significant as Zeus remains a powerful, often antagonistic, figure to Percy, the son of his brother Poseidon, throughout the series' overarching mythology.

The Returning Demigods and Olympians

A successful adaptation relies on the strength of its supporting cast, and many fan-favorite actors from Season 1 are confirmed to return, continuing their roles as fellow demigods and powerful Olympians. Their presence ensures continuity and deepens the topical authority of the series.

The Returning Camp Half-Blood Demigods

• Charlie Bushnell as Luke Castellan: The son of Hermes, whose betrayal was the shocking climax of The Lightning Thief. His role will be crucial in *The Sea of Monsters* as he continues his service to the Titan Lord Kronos.
• Dior Goodjohn as Clarisse La Rue: The aggressive but ultimately loyal daughter of Ares. Clarisse is a central figure in the quest to retrieve the Golden Fleece, which is the main objective of Season 2.
• Olive Abercrombie as Clarisse's Cabin Mate: A minor but recurring character who adds flavor to the Camp Half-Blood environment.

The Returning Olympian Gods and Key Figures

While some gods may only appear in flashbacks or brief moments, several key figures are expected to reprise their roles, maintaining the divine presence that is central to the Greek mythology narrative.

The Future of the Demigod Saga: Season 3 and Beyond

The commitment to the source material is strong, with the series already renewed for a third season, which will adapt the third novel, *The Titan's Curse*. This long-term planning is a testament to the show's success and the dedication of the creative team, including author Rick Riordan, who is heavily involved in the production process.

The continuation of the story means more significant characters are yet to be cast. Fans are eagerly awaiting the announcements for key figures from *The Titan's Curse*, such as Thalia Grace (daughter of Zeus), Rachel Elizabeth Dare, and the powerful villain Atlas. The consistency of the main cast—Walker Scobell, Leah Sava Jeffries, and Aryan Simhadri—throughout the first five books of the original series is guaranteed, providing a stable foundation for the entire saga. The updated cast, focusing on the new additions for *The Sea of Monsters*, promises a faithful and exciting chapter in the demigod's journey to save Olympus and the mortal world from the rising threat of Kronos.
