Several high-profile fantasy series are in development, with producers aiming to surpass the impact of HBO's Game of Thrones. Projects based on popular books, games, and franchises promise expansive worlds and innovative storytelling. These adaptations span networks like Netflix, Amazon, and HBO, targeting releases in the coming years.
Building on HBO's Game of Thrones—which revolutionized television by proving the viability of big-budget high fantasy—and its spinoffs like House of the Dragon and A Knight of the Seven Kingdoms (previewed earlier in this series), along with projects like Aegon’s Conquest and Corlys Velaryon’s voyages, the Westeros universe continues to expand.
Beyond this franchise, five notable upcoming fantasy TV shows are positioned to potentially exceed Game of Thrones' influence. At number five, Amazon MGM Studios is adapting Rebecca Yarros' novel Fourth Wing into a live-action series. Showrunner Meredith Averill oversees the story of a vulnerable scribe navigating a deadly dragon-rider program at Basgiath War College, produced with Michael B. Jordan’s Outlier Society. It draws from the BookTok community for its blend of survival, romance, and aerial combat.
Netflix's animated Magic: The Gathering adaptation, with showrunner Terry Matalas, has completed scripts for its first season and entered animatics. The CGI format allows depiction of the card game's vast multiverse, featuring interdimensional jumps and mythical creatures.
Also at Netflix, The Forgotten Realms revives a Dungeons & Dragons series with executive producer Shawn Levy and showrunner Drew Crevello. This live-action project crafts an original narrative in the iconic setting, emphasizing optimistic roleplaying adventure over grimdark tones.
Prime Video's The Dark Tower, developed by Mike Flanagan from Stephen King's works, has finished first-season scripts. It follows the Gunslinger's multiverse quest, combining horror, western, and weird fiction across seasons and films.
Topping the list, HBO's Harry Potter reboot targets a 2027 premiere under showrunner Francesca Gardiner and director Mark Mylod. New cast members include Dominic McLaughlin as Harry Potter, Arabella Stanton as Hermione Granger, and Alastair Stout as Ron Weasley, expanding on the Wizarding World's global appeal with deeper exploration of its lore.
