In 2026, news broke that a live-action adaptation of Matt Dinniman’s LitRPG series Dungeon Crawler Carl is in active development, making it one of the most anticipated upcoming fantasy shows based on books. Meanwhile, Prime Video’s animated The Mighty Nein—adapted from a Critical Role Dungeons & Dragons campaign—debuted in 2025 to a perfect 100% Rotten Tomatoes score and has already been renewed for a second season. These two projects, operating in parallel, reveal contrasting strategies for turning indie storytelling phenomena into television franchises.

The Animated Eight-Episode Arc That Already Won Over Critics

According to the report, The Mighty Nein aired an eight-episode first season on Prime Video, featuring voice actors Laura Bailey, Ashley Johnson, and Matt Mercer. its 100% Rotten Tomatoes score places it among the most critically acclaimed fantasy series of the year, regardless of mdeium. As the source notes, the show is set in its own universe separate from official D&D settings, a creative choice that mirrors the source material’s original campaign. The concise episode count provides a manageable entry point into Exandria, building on the earlier hit The Legend of Vox Machina.

Seth MacFarlane and the Uncertain Path from Podcast to Peacock

On the other side of the fantasy adaptation landscape, Dungeon Crawler Carl is being developed for Peacock with executive producers Seth MacFarlane and Chris Yost, with author Matt Dinniman also serving as an executive producer. The project was announced in 2024, but as the report emphasizes, a full series order has not yet been guaranteed. The source describes the logline: a post-apocalyptic scenario where survivors are forced into a brutal intergalactic game show, with Carl partnering with his ex-girlfriend’s cat, Princess Donut, to battle monsters, aliens, and a sadistic AI. Dinniman has stated that the production team will not proceed if the result looks subpar, signaling a cautious approach to budget and creative execution.

Both Shows Reject Official D&D Canon – And That’s the Point

A striking commonality between the two adaptations is their independence from official Dungeons & Dragons lore. The Mighty Nein operates in the homebrew world of Exandria, while Dungeon Crawler Carl has no connection to D&D at all, originating as a self-published LitRPG series. As the source reports, both shows are set in their own unique universes, which allows them to avoid the creative constraints and licensing hurdles of adapting established Wizards of the Coast properties. This trend suggests that studios are increasingly willing to greenlight projects that grow out of tabletop culture rather than the official brand itself.

What We Still Don’t Know About the Cast and Budget

The report leaves several important questions unanswered. No casting announcements have been made for Dungeon Crawler Carl, nor has a production budget or timeline been disclosed. It is also unclear whether the live-action adaptation will retain the darkly comedic tone of the books or pivot toward a broader audience. On The Mighty Nein side, the source does not reveal how much Amazon invested in the second season or whether the full Critical Role cast will return. Given the 100% critical score, the pressure to maintain quality in the sophomore run is high—and the lack of detail on production scale is a notable gap.
