• Lance Reddick as Zeus: The King of the Gods and ruler of Olympus. (Reddick's performance was one of his final roles before his passing).
• Toby Stephens as Poseidon: God of the Sea and Percy’s father.
• Jay Duplass as Hades: God of the Underworld.

The core trio is confirmed to return, but the expansion of the cast for *The Sea of Monsters* introduces fan-favorite characters who will become permanent fixtures in the demigod world.

Topical Authority: Comparing the Disney+ Series vs. The Original Films

When discussing the "Percy Jackson movie cast," it is impossible to ignore the two original films: *Percy Jackson & The Olympians: The Lightning Thief* (2010) and *Percy Jackson: Sea of Monsters* (2013). The new Disney+ series has been universally praised for its casting accuracy, a direct result of Rick Riordan's hands-on involvement.

The core difference lies in the age and faithfulness of the actors to the source material. The original films cast significantly older actors—Logan Lerman, Alexandra Daddario, and Brandon T. Jackson were all in their late teens/early twenties when filming began, whereas the book characters were twelve. The Disney+ series cast, led by Walker Scobell, Leah Sava Jeffries, and Aryan Simhadri, are much closer to the book-accurate age range, allowing for a more authentic portrayal of the demigods growing up in the world of Camp Half-Blood.

Furthermore, the Disney+ series has been able to attract a higher caliber of respected dramatic and comedic actors for the Olympian Gods, including Lance Reddick and Toby Stephens, lending a weight and gravitas to the divine roles that was often missing from the original movie adaptations. This commitment to casting has secured the series' status as the definitive, fresh adaptation of the beloved novels.
