It was recently announced that an Eragon television reboot is coming to Disney+! The show will adapt the first book in the Inheritance Cycle.
Christopher Paolini’s involvement
The show is in early development, so we know very little at this time. However, what we do know is great news for Inheritance Cycle fans: Christopher Paolini will produce and co-write the show! In a statement, Christopher said:
I’m attached to both co-write and produce! And yes, I’m extremely excited for what the future holds. At the moment, I can’t go into details—it’s still early days with regard to this project—but I can say that I’m very pleased with the team I’m working with at 20th Television, Disney Branded Television, and Disney+. These are smart, passionate people, and I’m looking forward to making the best possible Eragon/Inheritance Cycle adaptation with them.
Bert Salke, the show’s executive producer
Bert Salke, who is also working on Disney’s Percy Jackson and the Olympians adaptation, is executive producing the show. He offered a little insight into where development stands:
“Like with Percy Jackson, 20th and D+ are providing a chance for us to translate these stories to film in the way their millions of fans deserve. We’re incredibly excited to find the showrunner/partner who will help us bring the Eragon story to screens around the world.”
From what we know now, it seems that the team is actively seeking a showrunner, who will oversee the entire show’s creation. Additionally, we can speculate that Christopher (and any unannounced co-writers) will be at work writing the first few episodes, or at least the pilot episode (first episode). From there, Disney and 20th Century executives would offer feedback and ultimately approve the scripts, allowing the show to move forward.
We’ll be going into more detail on this process in a future article!
Casting and filming
We’re a ways away from any casting announcements or the beginning of filming. This will come after the studio approves the first script(s) for production. A hunt will begin, and with a huge property like the Eragon series, it’ll be likely that we hear all about the first casting calls!
Christopher has said that while they’re not at the casting stage yet, both he and the people behind the show have specific names in mind for actors they’d like to see join the cast! Of course, he wasn’t ready to share who those people are! 
Filming won’t start until 2023 at the earliest.
