Dafne Keen Joins ‘Percy Jackson and the Olympians’ Season 3: Rising Star Completes Disney Franchise Hat Trick as Artemis

A Monumental Casting Coup for Rick Riordan’s Fantasy Universe

Disney+ has pulled off what fantasy television enthusiasts are already declaring the ultimate franchise casting coup of 2026. As production gears up in Vancouver for the highly anticipated third installment of Percy Jackson and the Olympians, celebrated author and executive producer Rick Riordan has officially confirmed that Dafne Keen will join the series in the pivotal role of Artemis, goddess of the hunt and wild nature. The casting announcement instantly sent shockwaves through global fandoms, marking an unprecedented milestone for the 21-year-old actress as she becomes one of the only stars in modern entertainment history to hold major roles across three flagship Disney mega-franchises.

From Marvel’s X-23 and Star Wars’ Jecki Lon to Olympus

Dafne Keen’s ascent into Hollywood royalty has been nothing short of extraordinary. After breaking out as the ferocious Laura / X-23 alongside Hugh Jackman in Logan and reprising her fan-favorite role in Marvel Studios' mega-hit Deadpool & Wolverine, Keen pivoted to a galaxy far, far away with her standout turn as Padawan Jecki Lon in Lucasfilm’s The Acolyte. Stepping into the shoes of the fierce, moon-reigning protector of young maidens in The Titan's Curse storyline feels like a tailor-made union of actress and mythological role. Keen will share intense, mythical scenes with series lead Walker Scobell (Percy Jackson), alongside co-stars Leah Sava Jeffries (Annabeth Chase) and Aryan Simhadri (Grover Underwood).

Adapting 'The Titan’s Curse' with Darker Stakes and Cinematic Scale

Season 3 tackles one of the darkest, most beloved volumes in Rick Riordan’s literary saga. As Percy and his companions embark on a treacherous winter quest to rescue Artemis and Annabeth from the clutches of the awakening Titan lord Kronos, the series promises a noticeably mature tonal evolution. Disney Branded Television and 20th Television have significantly boosted practical set builds and stunt choreography to bring the mythological monster battles of Mount Tamalpais to life. Keen’s proven prowess in intense action sequences gives the production an immediate edge that has longtime book purists cheering.

The Future of Mythological Television on Disney+

Dafne Keen’s arrival as Artemis injects fierce star power into an already flourishing franchise. With Percy Jackson and the Olympians hitting its stride with faithful storytelling and stellar world-building, Season 3 is shaping up to be an unmissable streaming spectacle when it lands on Disney+.
