As of June 2012, there are no reported plans to make a film adaptation of Eldest.
Eldest is the second novel in the four-book fantasy series the Inheritance Cycle by Christopher Paolini, which focuses on a boy named Eragon and his dragon, Saphira. Eldest follows after Eragon, which was made into a film in 2006.
Before the film Eragon came out, Christopher Paolini was asked about the possibility of making a film adaptation of Eldest, and replied “I think we’ll know after opening weekend.” Many fans of the novel were disappointed with the film Eragon as it didn’t stay particularly true to the book, and it wasn’t very popular with those unfamiliar with the Inheritance Cycle series either. It was criticised for being lifeless and for lacking depth. Rotten Tomatoes, the trusted film review website, gave the film a rating of only 16%.
As a result of this largely negative reception of Eragon the movie, it therefore doesn’t seem likely Eldest will be made into a film any time soon.
