The Definitive List: Every Major Star Cast In Disney+'s Percy Jackson And The Olympians (Season 1, 2, & 3 Updates)
The long-awaited live-action adaptation of Rick Riordan's beloved series, Percy Jackson and the Olympians, has finally secured its place as a massive hit for Disney+, and the casting decisions have been a central part of its success. As of this current date, December 23, 2025, while Season 2 is in production, the most exciting news revolves around the major star power being added to the already announced Season 3, which will adapt the fan-favorite book, The Titan's Curse. This article breaks down the full cast from the iconic main trio to the star-studded lineup of gods and the newest additions that promise to make the upcoming seasons even more epic.
The journey from the original, critically panned movies to this author-approved, highly-anticipated series has been a long one for Demigods worldwide. With author Rick Riordan deeply involved in every step of the production, the casting for the series has been a meticulous process, resulting in a fresh and dynamic ensemble that has captured the spirit of the books, despite initial fan controversy that the author himself shut down.
The Main Trio and Complete Cast Biography (Seasons 1-3)
The core of the Percy Jackson saga rests on the shoulders of the three main heroes: Percy, Annabeth, and Grover. Their casting was the most scrutinized and ultimately, the most celebrated aspect of the first season. Beyond them, a massive ensemble of Hollywood veterans and rising stars fill the roles of the Greek gods, camp staff, and mythical figures.
The Core Demigods: Walker, Leah, and Aryan
- Walker Scobell as Percy Jackson: The titular hero, son of Poseidon. Scobell was already known for his role in the Netflix film The Adam Project, and his casting was praised for capturing Percy's blend of sarcasm and vulnerability.
- Leah Sava Jeffries as Annabeth Chase: Daughter of Athena. Jeffries’ casting was met with initial, regrettable backlash from a small section of the fandom, which author Rick Riordan vehemently and publicly condemned, calling her the perfect Annabeth. She is a rising star known for her work in Beast.
- Aryan Simhadri as Grover Underwood: Percy’s best friend and a satyr. Simhadri is a talented actor who brings the perfect mix of anxiety and loyalty to the role of the nervous but brave protector.
The Olympian Gods and Camp Half-Blood Staff (Season 1 & 2)
The series is packed with A-list talent portraying the gods and key figures from Camp Half-Blood, establishing a high level of topical authority and star power:
- Virginia Kull as Sally Jackson: Percy’s mother, known for her unconditional love and strength.
- Glynn Turman as Chiron: The immortal centaur and activities director at Camp Half-Blood.
- Jason Mantzoukas as Dionysus (Mr. D): The God of Wine and the reluctant camp director.
- Adam Copeland (Edge) as Ares: The God of War, a formidable and arrogant foe for Percy.
- Timothy Omundson as Hephaestus: The God of Fire and Forges.
- Lin-Manuel Miranda as Hermes: The messenger of the gods, known for his work in Hamilton and Encanto.
- Megan Mullally as Alecto (Ms. Dodds): One of the Furies and a substitute algebra teacher.
- Lance Reddick as Zeus: The King of the Gods (Season 1).
- Toby Stephens as Poseidon: The God of the Sea and Percy's father.
The Shocking New Cast Members for Season 3: The Titan's Curse
While Season 2 is set to adapt The Sea of Monsters, the most recent and exciting casting news is for the highly anticipated Season 3, which will tackle the events of The Titan's Curse. These new additions signal a major expansion of the series' scope and star power, focusing on the Hunters of Artemis and the Titan war.
The casting announcements for Season 3 are the freshest updates, confirming that the series is committed to bringing major book characters to life with significant talent. This focus on the third book, which introduces key figures in the war against Kronos, has generated massive buzz in the fandom.
Major Season 3 Additions: New Gods, Hunters, and Titans
- Dafne Keen as Artemis: The Greek Goddess of the Hunt, the Moon, and the Wilderness. Keen is a major casting coup, known globally for her breakout role as X-23 in the movie Logan and her lead role in the HBO/BBC series His Dark Materials. Her casting as the powerful Olympian goddess is a huge win for the series.
- Saara Chaudry as Zoë Nightshade: The fiercely loyal and tragic lieutenant of the Hunters of Artemis. Chaudry is a talented young actress known for her work in The Breadwinner and The Mysterious Benedict Society. Her portrayal of the fan-favorite character is expected to be a highlight of Season 3.
- Holt McCallany as Atlas: The formidable Titan who holds up the sky. McCallany, known for his intense roles in series like Mindhunter, brings a powerful presence to one of the most physically demanding and emotionally complex antagonists in the series.
The Topical Authority: Why This Casting is a Game-Changer
The casting strategy for Percy Jackson and the Olympians has been a masterclass in balancing fan expectations with creative freedom. Unlike the previous movie adaptations, which largely failed to capture the essence of the books, the Disney+ series has succeeded by adhering to two key principles: author involvement and prioritizing talent over strict adherence to physical descriptions.
Rick Riordan’s commitment to the project, serving as a writer and executive producer, ensured that the spirit of the characters—their personalities, humor, and relationships—came first. This approach is what gives the series its inherent topical authority over previous attempts. The author’s strong defense of Leah Jeffries’ casting as Annabeth Chase was a pivotal moment, cementing the show's commitment to finding the best actor for the role, regardless of outdated fan interpretations.
The casting of the gods with established actors like Lin-Manuel Miranda (Hermes), Megan Mullally (Alecto), and the late Lance Reddick (Zeus) serves a dual purpose. It gives the series immediate gravitas and star recognition while also accurately portraying the Olympians as powerful, often temperamental, and occasionally quirky figures who interfere in human affairs.
Looking Ahead: The Future of the Demigod Universe
With Season 2 (adapting The Sea of Monsters) on the horizon and Season 3 (The Titan's Curse) already locking in major new cast members like Dafne Keen and Saara Chaudry, the future of the Percy Jackson universe is brighter than ever. The continued success of the Disney+ series is not only a win for fans of The Lightning Thief but also opens the door for adaptations of Riordan's broader "Camp Half-Blood Chronicles," including the popular Heroes of Olympus sequel series.
The production team’s willingness to cast major roles far in advance, as seen with the Season 3 announcements, demonstrates a long-term commitment to the franchise. This proactive approach ensures a seamless transition between the books, allowing the young main cast to grow into their roles naturally, mirroring the characters' aging process throughout the novels. This dedication to authenticity, led by Riordan and realized through meticulous casting, is the true secret behind the show’s success and its lasting appeal to a new generation of demigods.
