film — specifically, as a warrior who is beheaded in the battle of Farthen Dûr. However, he was unable because of his European book tour. Jeremy Irons, who welcomed the opportunity to reintroduce himself to younger audiences, took on the role although Dungeons & Dragons (a previous fantasy film he had acted in) had flopped, and he said that he thought that Eragon "had been better managed" than that film. Filming In August 2005, Fox began filming Eragon at various locations throughout Hungary and Slovakia, including: Pilisborosjenő, Budapest Metropolitan Area, Hungary Budapest, Hungary Ság-hegy, Hungary Celldömölk, Hungary High Tatras, Slovakia Filming ended a month later in September, beginning the film's post-production stage, with Industrial Light and Magic creating the film's CGI. The decision was made later on in production to add feathers to the standard bat-like wings of the dragon Saphira. The studio had been inspired by the Angel's wings in X-Men: The Last Stand. Jean Bolte, lead viewpaint artist for ILM on the film, calls them "skethers" (half-feathers, half-scales) and was inspired by the scales of the pangolin. It was eventually decided that Saphira's colors scheme should be subdued rather than vibrant in order to be more realistic. Music The score for the film was composed by Patrick Doyle who also created the score of 2005's Harry Potter and the Goblet of Fire. Avril Lavigne also recorded the film's theme song, entitled "Keep Holding On", which was featured in the credits and on the soundtrack. The track was released as a single in 2006 (and later as a track on her 2007 album The Best Damn Thing) and reached 17 on Billboard Hot 100 singles chart in America.
