Always felt like that Eragon series could have been good. Too bad they never made a movie for it. Never once. I'm sure it would have been solid if they had. But they didn't.
I think they are making an Eragon adaptation (for the first time, of course). I think Disney+ is making a series, similar to them restarting Percy Jackson.
Ah, it appears you have forgotten or have simply Mandela'd in from a different timeline. Allow me to refresh your memory for you in the kindest way possible:
Eragon was a 2006 dance film featuring Jeremy Irons and Ed Speeler on a ship. Some fighting is involved. And I dunno, a dragon maybe.
I feel the same way about Avatar: The Last Airbender. It would have been such an amazing movie, or perhaps even a series. But alas, they've never attempted it once.
