Naruto the book starts off at the middle of the second stage of the chunin exams and follows Naruto, Sasuke, and Sakura into the third stage.
Naruto the movie follows the trio throw most of the second stage of the chunin exams.
Naruto the book and Naruto the movie are pretty similar except for the wording. For example in the movie Kakashi says, " Who said Naruto was out of gas?" In the book he says " Trust the ultimate maverick ninja to turn breaking wind into an attack move."
