Film- Carvahall is swarming with soldiers.

Book- Horst is described as a big, hulking, bulky blacksmith with brisky black hair, and a rumbling voice - confident, brave, whole-hearted, and optimistic. His wife Elain is blonde.
Film- Horst is portrayed as somewhat a rather smaller man with a balding head (and it is never mentioned that he is a blacksmith). His voice is not husky. He turns out to be vulnerable, pessimistic, worrying, and broken-hearted. His wife, Elain, is a brunnete.

Book- Horst, his wife Elain, and their sons, Albriech and Baldor, remain in Carvahall up to the end of the book and are seen or mentioned several times. There are many other villagers in Carvahall, including Fisk and Morn.
Film- Horst is seen briefly in two short scenes, Elain and her sons are seen briefly in one, and they do not play the parts they did in the book. Both sons are recruited into the Imperial Army and leave Carvahall early in the story. No villagers besides Horst, Eragon, and Roran are named.

Film- They travel to the Varden within a few minutes of movie time.

Book- Murtagh defeats Durza by shooting him with two arrows. Durza feels immense pain when he is disembodied.

Film- No such desert ever appears in the movie.

Book- Eragon learns how to summon water from the ground in the Hadarac Desert.
Film- No such magic is performed by Eragon.

Book- Farthen Dûr is a tall, hollow, almost invincible mountain with a hole in the top. It is over ten miles high. Tronjheim is a marble city mountain built inside the mountain.
Film- Tronjheim is made of wood and stone, and looks more like Tarnag, a dwarf city visited in Eldest, or a valley, rather than a mountain. The mountain itself is much less than ten miles high.

Book- There are scenes involving Hrothgar's throne room and Isidar Mithrim.
Film- There are no scenes involving Hrothgar's throne room or Isidar Mithrim.

Book- During the Battle under Farthen Dûr, Eragon attacks Durza with his mind and sees the Shade's past as a human named Carsaib, who lost control of his mind when evil spirits entered his body.
Film- Eragon does not attack Durza's mind, and learns nothing of the Shade's past.

Book- The battle between Durza and Eragon takes place on the ground, inside Tronjheim.
Film- Durza flies into battle against Eragon and Saphira on a beast of dark smoke or vapor, presumably created by magic. Durza has no problems creating or sustaining the Beast. This really violates the laws of magic, because not even a Shade has enough strength to conjure a dragon-like monster with a large structure and enough density to support someone's weight.

Book- Eragon defeats Durza when the Shade is distracted by Saphira flying overhead and breathing fire. Isidar Mithrim was shattered during the fight.
Film- Eragon defeats Durza by having Saphira throw him at Durza using her tail. Nothing, besides several wooden structures, was destroyed as a result of the fight.

Book- When Eragon blacks out after killing Durza, the-Cripple-Who-Is-Whole (Oromis) appears to him in a vision and advises him about Ellesméra. Arya remains in Tronjheim at the end of the story, but travels back to Ellesméra in the next book with Eragon and Orik.
Films- Eragon apparently has no vision of Oromis. Arya leaves for Ellesméra afterwards, without Eragon and Orik.

Other Differences:
On two movie posters (as shown above), Saphira is featured with bat-like membrane wings, but the movie features her with feathers.

The movie takes place over a much shorter time than the book. It is had been mentioned in several different sections that the film took place of about three days, while the story in the novel takes place over months. Also, a quote by Arya ("Yesterday, you were a farm boy. Today, you are a hero."), is very misleading. She says "yesterday" and "today" as figures of speech, not actual time periods.

In the book, Eragon is motivated to fight the Urgals because they hurt people. In the movie, he does so only to prove his strength.

In the novel, the story ends with Eragon promising to go to Ellesméra to resume his training with Oromis. But the movie never mentions the fact that he needsfurther training, and it ends with Eragon and Arya going their own ways, and Galbatorix unleashes his black dragon, Shruikan.

At the end of the film, Galbatorix unleashed Shruikan to go and attack Eragon. But that neverhappened in the first book; he is most logically going to have to fight Eragon and Saphira in Book 4!
