Big casting news for Percy Jackson fans
Disney+ has tapped Holt McCallany to play Atlas, the towering Titan known as the bearer of the heavens, in season 3 of Percy Jackson and the Olympians. The announcement raises the stakes for the series as showrunners move to adapt Rick Riordan's The Titan's Curse, the third book in his bestselling five-book saga. According to reports, McCallany will appear across six episodes and arrives at a pivotal moment: Atlas has recently been freed from his ancient punishment and is poised to rally Kronos' forces in a revenge-driven war.
New guest stars and familiar faces
Alongside McCallany, veteran character actor David Costabile joins season 3 as Dr. Thorn, the authoritarian head of a military academy whose demand for obedience creates immediate tension for Percy and his friends. Jesse L. Martin is also on board in a guest role as Frederick Chase, the brilliant but distractible military historian and father to Annabeth. Returning and continuing cast members who will anchor the season include actors portraying Artemis and Zoe Nightshade, plus the actors who play Nico and Bianca di Angelo.
What The Titan's Curse means for the show
Season 3 will follow the events of The Titan's Curse, where Percy must rescue the kidnapped goddess Artemis and his friend Annabeth after they fall into Atlas' clutches. The story brings darker tones and higher stakes compared with earlier installments, mixing epic battle sequences with emotional reunions and family drama. The show has so far balanced faithful adaptation with modern pacing, and this chapter gives the writers rich material to explore the consequences of war among gods and titans.
Fans of the books will recognize elements like Dr. Thorn's true identity, but showrunners are keeping key surprises under wraps to preserve the viewing experience. Casting choices like McCallany signal a move toward weightier, more menacing antagonists who can carry both physical presence and dramatic subtlety.
Context and creative notes
Percy Jackson's Disney+ reboot has been compared to other high-end YA adaptations that successfully blended faithful source adaptation with cinematic production values, such as His Dark Materials and the recent reinventions of fantasy franchises. The series also benefits from seasoned guest actors — Costabile's knack for playing sharp, intimidating figures in shows like Billions and Breaking Bad makes him a natural fit for a role that has layers beyond the surface menace.
Marko Jensen, cinema historian: 'Bringing a durable character actor like Holt McCallany into a mythic role adds a grounded intensity that CGI alone cannot provide. This season could redefine how YA mythic antagonists are portrayed on streaming TV.'
Production for season 3 is underway in Vancouver while season 2 continues to release weekly on Disney+. With Atlas back in play and new cast additions expanding the world, expectations among viewers and the Percy Jackson community are rising as the series ramps toward a darker, more action-driven arc.
Whether you follow the books closely or are discovering Riordan's universe through the show, season 3 promises a blend of mythic spectacle and character-driven drama that could be the series' most ambitious chapter yet.
