It seems unlikely that the sequel to Eragon will ever be made into a movie, particularly as Eragon was released in 2006 and there is still no word that the sequel is being produced. Eragon was released worldwide between December 13 and December 15, 2006 by 20th Century Fox. It was the 10th worst reviewed film of 2006 on Rotten Tomatoes, and the 31st highest grossing film of 2006 in the US.
The sequel to Eragon is Eldest which was first published in hardcover on August 23, 2005, and was released in paperback in September 2006.
Eldest begins following several important events in Eragon. The story is the continued adventures of Eragon and his dragon Saphira, centering around their journey to the realm of the Elves in order to further Eragon's training as a Dragon Rider. Other plots in the story focus on Roran, Eragon's cousin, who leads the inhabitants of Carvahall to Surda to join the Varden, and Nasuada as she takes on her father's role as leader of the Varden. Eldest ends at the Battle of the Burning Plains, where Eragon faces a new Dragon Rider, Murtagh and a new dragon, Thorn. Whether or not the book will be adapted to film remains a matter of speculation. When asked whether there would be a movie adaptation of Eldest at the premiere of Eragon, Christopher Paolini replied, "I think we'll know after opening weekend.”
Since the opening weekend passed, Paolini has not commented. Many critics have considered the possibility of a sequel in their reviews of Eragon. One critic said that 20th Century Fox's plans to adapt Eldest was "jumping the gun" and that "they will have a tough time convincing anyone but the most die-hard fans to return for another helping." Even some critics who gave the film positive reviews were sceptical towards the possibility of a sequel.
