10 Fascinating Fantasy Movies and TV Shows Stuck in Development Hell

10 Fascinating Fantasy Movies and TV Shows Stuck in Development Hell

Hollywood is currently teeming with a myriad of fantasy adaptations, yet many projects remain stagnant, lacking significant updates for years. Transforming popular fantasy literature into compelling film or television narratives presents a complex set of challenges. Following the immense success of Game of Thrones, the early 2020s witnessed a surge of interest from various streaming platforms eager to replicate its triumph. This resulted in the emergence of series like The Wheel of Time and House of the Dragon, alongside fresh expansions on classic titles such as The Lord of the Rings.

While numerous beloved fantasy worlds have been adapted for the screen, few, if any, have matched the critical or cultural resonance of Game of Thrones. Consequently, Hollywood’s willingness to greenlight new fantasy projects has diminished. Notably, Warner Bros. is still pursuing a reboot of the Harry Potter series and new films set in the LOTR universe. In contrast, lesser-known adaptations like Best Served Cold have been stalled amid development struggles exacerbated by the 2023 WGA and SAG-AFTRA strikes.

Brandon Sanderson’s renowned Mistborn series has yet to see a successful film adaptation, despite over a decade of attempts. In 2023, the author indicated that a movie adaptation was closer than ever to realization, featuring well-known actors. However, recent updates from Sanderson’s blog have revealed that the project has returned to its initial stages.

Sanderson’s Cosmere Universe, recognized for its captivating complexity, has the potential to parallel the appeal of the MCU. Nevertheless, its intricate magic systems and diverse world-building may impose a significant budgetary requirement, prompting studios to exercise caution in an era where many fantasy projects are faltering.

The development of The Kingkiller Chronicle has become a symbolic conundrum, intertwined with the status of its final book, which has kept fans waiting since 2011.

Initially announced in 2015, this adaptation caught attention with Lionsgate set to produce. In 2017, acclaimed creator Lin-Manuel Miranda joined as an executive producer, later joined by director Sam Raimi in 2018. However, as of January 2025, updates on this highly anticipated project have been sparse.
